2.6.2 The Structure, Function and Working Principle of the Main Components

2.6.2.1 Machine Bed

The bed is welded with high-strength steel. The main production process is as follows:

Annealing to eliminate internal stress→rough machining→vibration aging→semi-finishing→ vibration aging→finishing. Through this process, the stress will be eliminated more thoroughly, which reduces the deformation of the machine tool and ensures its long-term accuracy.

The AC servo motor drive is controlled by the CNC system, coaxially driving the beam to reciprocate along the Y direction, realizing fast movement and feeding motion; the rack, pinion and the linear guide rail are equipped with the closed dust-proof device, which is light in weight and reliable in operation; the rack and pinion and the linear guide rail are all imported precision products, which effectively guarantee the accuracy of the transmission; both ends of the stroke are controlled by soft limit switches, together with elastic cushion on each side to effectively ensure the safety of machine tool movement.

2.6.2.2

Beam

The beam is cast with high-strength aluminum alloy as a whole. After solution treatment and artificial aging, it is machined to ensure the overall rigidity and strength. The main production process is as follows:

Rough machining→vibration aging→semi-finishing→vibration aging→finishing. The beam is installed on the supporting guide rail of the bed and high-quality linear guide rails are installed on the beam (There are linear guide rails and flat guide rails). The servo motor drives the gear to rotate through the reducer, so that the Z-axis slide plate can reciprocate in the X direction. During the movement, there is a soft limit switch to control the stroke, at the same time, there are limit switch and elastic buffers at both ends to ensure the safety of the system operation;

The top and both sides of the beam are closed by the outer cover, and a retractable organ-type protective cover is installed between the beam and the horizontal slide plate to ensure that the rack and linear guide rail run in a fully enclosed environment without being affected by the external environment.

2.6.2.3

8) Other precautions

a) During the working of the laser source, please pay attention to the normal operation of the water circuit, gas circuit and electric circuit. Otherwise, please turn off the power to detect and check the cause;

b) If there is any failure during the operation, please record the time, failure phenomenon, and system working status, and then check the cause of the failure. If you have any questions, please contact us.

B. Adjustment of the co-axiality between the nozzle hole and the laser beam

The steps are as follows:

1) Apply ink paste (usually red is better) on the outlet end of the nozzle, and stick the self-adhesive tape there, as the picture shows.

4.3.1-1. Step 1

2) Use 10~20 watts of power to punch holes manually.

3) Remove the self-adhesive paper. Pay attention to maintaining its orientation, so that it can be compared with the nozzle.

4) Under normal circumstances, there will be a black spot on the self-adhesive paper, which is burned by the laser. But the black spot will not be visible (the laser beam hit the wall of the nozzle) if the center of the nozzle deviates too much from the center of the laser beam.

Figure

Figure 4.3.1-2. Nozzle deviation is too much

Please pay attention to whether the conditions are consistent and whether the focusing lens is loose if the sizes of the center points are inconsistent.

Figure 4.3.1-3. Focusing lens is loose

Pay attention to the direction where the black dot deviates from the center of the nozzle, and adjust the position of the nozzle.

Figure 4.3.1-4 Adjust the nozzle to be coaxial with laser beam

5) Nozzle aperture

Aperture size has a critical impact on cutting quality and piercing quality.

If the nozzle hole diameter is too large, the melt splashed around during cutting may pass through the nozzle hole, thereby splashing the lens. The larger the aperture, the higher the probability, the worse the protection of the focusing lens, and the shorter the lens life.

4.3.2 Function and Adjustment of Nozzle

4.3.2.1 Nozzle

The nozzle is a consumable product: the design, the flow of the jet air and the manufacturing accuracy directly affect the cutting quality. Its main functions are:

Prevent debris such as cutting melt from bouncing up into the cutting head and damaging the focusing lens.

The nozzle can change the state of the cutting gas ejection, and can control the area and size of the gas diffusion, thus affecting the cutting quality. The picture below shows the gas ejection situation when the nozzle is installed and not installed.

4.3.2.2

Figure 4.3.2.1-1. The cutting gas situation with or without nozzle

Influence of Nozzle on Cutting Quality and Selection of Nozzle Aperture

The relationship between nozzle and cutting quality:

When the center of the nozzle and the laser are not coaxial, the impact on the cutting quality:

It affects the cutting section. When the cutting gas is ejected, the gas volume is uneven, so that the cutting section is more likely to have melted stains on one side and not on the other side. It has little influence on cutting thin sheet below 3mm. But its impact will be serious when cutting sheet above 3mm, and sometimes the sheet cannot be cut.

It affects the cutting quality of sharp corners. When cutting workpieces with sharp corners or small angles, local over-melting is prone to occur. In this case, it may not be able to cut thick sheet.

It affects the perforation. It is unstable during the perforation and the time is not easy to control. The penetration of the thick plate will cause over-melting and the penetration condition is

not easy to grasp. But it has little effect on the perforation of thin sheet.

To sum up, the concentricity between the center of the nozzle and the laser is one of the most important factors that affect cutting quality. Especially when the workpiece to be cut is thicker, its influence will be greater. Therefore, the concentricity between them must be adjusted to obtain a better cutting section.

Note: When the nozzle is deformed or there are melted stains on it, its impact on the cutting quality is the same as that described above. Therefore, the nozzle should be placed carefully, and it should not be damaged to avoid deformation. The melted stains on the nozzle should be cleanedup in time. It has high precision requirements during manufacture and correct installation. If the cutting conditions are changed due to the poor quality of the nozzle, it should be replaced in time.

Choice of nozzle aperture

The cutting conditions of nozzles with different apertures are shown in the table below.

Table 4.3.2.2-1. Relationship between aperture and auxiliary gas flow rate

The larger the nozzle hole diameter, the worse the lens protection. Melt may splash upward during cutting, shortening the life of the lens.

4.3.3 Adjustment of Beam Focus

4.3.3.1 Introduction

It is very important to adjust the focus position correctly. During cutting, the relative position of the beam focus and the surface of the cutting sheet has a great influence on the cutting quality. Generally, the best focus cutting position can be directly obtained by changing the focus and performing the trial cutting, and it can be adjusted by rotating the nut on the laser head.

4.3.3.2

Relationship between Focus Position and Cutting Section

The table below lists the positions of the laser cutting focus, its impact on the piercing and cutting section, and the selection of the focus position when cutting different sheets.

Name and location of focus

Zero focal length: The laser focus is on the surface of the cutting workpiece.

Cutting materials and section characteristics

SPC, SPH, SS41 and other workpieces.

The focus is on the surface of the workpiece. The upper surface is smooth and the lower surface is not smooth.

Carbon steel, aluminum and other workpieces.

Positive focal length: The laser focus is on the upper surface of the cutting workpiece.

Negative focal length: The laser focus is on the lower surface of the cutting workpiece.

The focal point is in the center, so the range of the smooth surface is larger, the cutting width is wider than that of zero focal length, the gas flow rate is larger during cutting,and the piercing time is longer than that of zero focal length.

Stainless steel sheet.

When cutting stainless steel, high-pressure nitrogen is used to blow off the slag and protect the section, and the cutting width increases as the thickness of the workpiece increases.

Table 4.3.3.2-1. Relationship between focal point and cutting materials

4.3.4 Set the Distance between Nozzle and Workpiece

4.3.4-1. Distance between nozzle and workpiece

After adjusting the sensor adjustment box, the Follow distance between the nozzle and the workpiece is mainly determined by the technic parameters. Please refer to the technic parameter table for details.

4.3.5

Selection of Laser Cutting Speed

Cutting speed is determined according to the material and thickness of the cutting sheet. It has a great impact on the cutting quality. With an appropriate cutting speed, you can not only improve the cutting efficiency, but also get good cutting quality. The influence of different cutting speeds on cutting quality is discussed below:

Its impact on the cutting quality if the speed is too fast:

It may cause the cutting to fail and sparks to fly.

Some areas can be cut off, but some cannot.

The entire cutting section is rough, but there is no melting stain.

Figure

As shown in the figure, the cutting speed is too fast, so that the sheet cannot be cut in time. The cut section shows oblique stripes, and the lower half of the sheet is melted.

Influence of too slow speed on cutting quality:

It may cause the cutting sheet to be over-melted with rough cutting section.

The cutting gap will widen accordingly, causing the melt at smaller rounded corners or sharp corners, and the ideal cutting effect cannot be obtained.

The cutting efficiency is low.

Speed selection:

The speed can be judged from the cutting sparks: Generally, the cutting sparks diffuse from top to bottom. The speed is too fast if the sparks are inclined; the speed is too slow if the sparks do not spread and the number is small. Appropriate cutting speed is as shown in the figure below: the cutting surface has smooth lines, and there is no melting stain on the lower half.

Figure 4.3.5-1. Cutting effect

Figure 4.3.5-2. Relationship between cutting speed and sparks

4.3.6 Selection of Laser Cutting Gas and Pressure

During laser cutting, different cutting gases should be selected according to the material of the cutting sheet. Cutting gas and its pressure has a great influence on the quality of laser cutting.The main functions of the cutting gas are: combustion-supporting and heat dissipation, timely blowing off the molten stains generated during cutting, preventing the cutting molten stains from rebounding upwards into the nozzle, protecting the focusing lens, etc.

1. The influence of cutting gas and pressure on cutting quality:

The cutting gas helps to dissipate heat and support combustion, and blow off the molten stains, so as to obtain a better cutting section.

A. When the pressure of the cutting gas is insufficient, it will have the following effects on the cutting quality: melting stains will occur during cutting, and the cutting speed cannot meet the production efficiency.

B. When the pressure of the cutting gas is too high, its impact on the cutting quality: the cutting surface is rough, and the cutting gap is wide; at the same time, it will cause partial melting of the cutting surface, and a good cutting section cannot be obtained.

2. The influence of cutting gas pressure on piercing:

A. When the gas pressure is too low, the laser is not easy to pierce the cutting sheet, so that the piercing time increases, resulting in low productivity.

B. When the gas pressure is too high, it will cause the piercing point to melt and form a larger melting point, which will affect the cutting quality.

When piercing, generally higher gas pressure is used for thin sheet, while lower gas pressure for thick one.

When cutting ordinary carbon steel, the thicker the sheet, the lower the pressure of the cutting gas. When cutting stainless steel with nitrogen, the cutting gas pressure increases relatively with the thickness of the sheet, and the cutting gas pressure is always high.

In short, the choice of cutting gas and pressure must be adjusted according to the actual situation. In specific applications, corresponding cutting parameters should be selected.

4.3.7 Effect of Laser Cutting Power on Cutting Quality

During cutting, laser power also has a certain impact on the cutting quality. It needs to be determined according to the material and thickness of the cutting sheet. If the power is too large or too small, a good cutting section cannot be obtained.

1. If the laser power is too small, cutting will not be possible.

2. When the laser power is too high, the entire cutting surface will be melted, and the cutting gap will be too large, so good cutting quality cannot be obtained.

3. When the laser power is insufficient, cutting melt stains will occur, and scars will appear on the cutting section.

Therefore, if the laser power is set appropriately, and with the appropriate cutting gas and pressure, good cutting quality can be obtained without melting spots.

5 Maintenance and Troubleshooting

5.1 Maintenance

5.2 Fault Analysis and Troubleshooting

5.2.1 Fault Analysis of Follow System

 Alarm and abnormal problem analysis

1) The upper/lower limit is valid

This alarm will be generated when the system detects that the upper limit or lower limit photoelectric switch or contact sensor on the Z-axis is valid. At this time, the following situations should be paid attention to:

Whether the limit signal line is connected normally.

Whether the "limit signal " parameter is set correctly, the limit signal can be set as normally open or normally closed.

Whether the upper/lower limit does sense the object and outputs a valid level signal.

Whether the sensor is damaged, or there is oil or dust.

2) Exceeding the Z-axis stroke

This alarm will be generated when the Z-axis coordinate of the system is greater than the set stroke. If a false alarm occurs, please note whether the system is reset correctly, whether the

travel parameters are set correctly, and whether the encoder feedback is normal.

3) The upper limit is always effective

This alarm will be generated when the machine returns to the origin, touches the negative limit, and then goes back, but cannot exit the area of the negative limit.

4) Servo alarm

The system will generate a servo alarm when the ALM signal of the No. 14 interface of the servo interface detects that there is a servo alarm signal input. The following reasons may cause the servo alarm on the height controller:

The servo motor alarms, in this case, check the servo motor drive to see if there is an alarm, if so, power on again.

5) The encoder changes abnormally

This alarm will be generated when the system is in a static state and it is detected that the feedback value of the encoder has changed. Reasons for this alarm include:

The external force causes the shaft to vibrate.

The line is in poor contact, and the zero-speed clamp signal is invalid.

The encoder line is disturbed, in this case, confirm whether the machine is connected to the ground correctly.

6) The encoder does not respond

This alarm will be generated when the system sends out the analog value and detects no

change in the encoder signal. Reasons for this alarm include:

The line is not in good contact, the analog signal is not sent to the servo, or the zero-speed clamping signal is always in effect, or the feedback signal of the encoder is not correctly sent to the height controller.

7) The position deviation is too large

This alarm will be generated when the system detects that the difference between the feedback position and the target position is too large. This alarm generally indicates that the servosystem cannot normally follow the position loop command of the height controller. Reasons for this alarm include:

The direction of the encoder is reversed. The position loop of the system does not form negative feedback. In this case, the parameters need to be modified.

Wiring, interference, etc. lead to abnormal encoder feedback.

The Z-axis is mechanically stuck. The torque of the system increases instantaneously, but the Z-axis is not in place in time.

8) Capacitance becomes 0

The capacitance value will become 0 when the system cannot measure the capacitance correctly. Reasons are as follows:

The cutting head touches the surface of the sheet.

The cutting head is flooded with water.

The local capacitance of the cutting head is too large and exceeds the detection range.

The amplifier is damaged.

Poor contact in amplifier/cutting head wiring.

Inside the cutting head, the positive pole (nozzle) and negative pole (machine shell) of the induction capacitor are short-circuited.

9) The local capacitance becomes smaller

This alarm is caused when the system detects that the local capacitance becomes smaller than a certain range. The reasons include:

The alarm may also be caused by changing accessories, or changing connections, or random changes in the characteristics of analog components. At this point, re-calibration needs to be done.

The laser scatters onto the nozzle, causing the temperature of the nozzle to rise sharply, resulting in temperature drift.

Blowing air causes the gap between the positive electrode (nozzle) and negative electrode (cutting head housing) to change.

Poor contact of the connecting wires of the amplifier and nozzles.

It may also cause this alarm if the calibration distance is set too small (less than 10mm in 3D and less than 15mm in 2D).

10) The capacitance becomes larger

When the system is enabled to Follow, the Follow action will go up all the time because the capacitance becomes larger, and this alarm will be generated. Reasons for this alarm include:

The alarm may also be caused by changing accessories, or changing connections, or random changes in the characteristics of analog components. At this point re-calibration needs to be done.

The laser scatters onto the nozzle, causing the temperature of the nozzle to rise sharply, resulting in temperature drift.

Blowing air causes the gap between the positive electrode (nozzle) and negative electrode (cutting head housing) to change.

Poor contact of the connecting wires of the amplifier and nozzles.

11) The capacitance becomes abnormally large

This alarm is caused when the system detects that the capacitance exceeds the maximum value during calibration, or the set hit board capacitance. Reasons for this alarm include:

The cutting head touches the surface of the sheet.

A small amount of water has entered the cutting head.

The laser scatters onto the nozzle, causing the temperature of the nozzle to rise sharply, resulting in temperature drift.

Blowing air causes the gap between the positive electrode (nozzle) and negative electrode (cutting head housing) to change.

12) The Follow error is too large

This alarm will be generated when it detects that the distance from the sheet becomes abnormally large instantaneously when the system is in the Follow state. Reasons for this alarm include:

Cutting beyond the scope of the sheet, and there is no object under the cutting head to follow.

The board vibrates considerably.

13) The usage time has expired

The set time is up.

 FAQ Analysis

1) There are obvious jitters and mechanical shocks when following.

The amplifier housing or the controller FG foot is in poor contact with the machine housing.

The machine housing is the negative pole of the tested capacitance. When the amplifier housing and the machine housing have poor electrical conductivity, the AC impedance between the positive and negative poles of the capacitance will be larger. This will cause changes in the measurement circuit load, resulting in significant measurement errors. If it is not possible to achieve a good mechanical connection, an additional wire should be added between the amplifier and the machine metal housings to reduce the AC impedance. However, the AC impedance using this singlepoint connection method is larger than that of a good mechanical connection. The specific index should be less than 10 ohms of DC impedance.

The levels of follow motion are set too high.

It will cause shaking during movement if the levels of follow motion are set too high. It is recommended to use 10~18 levels.

Poor calibration of the cutting head

Jitter will occur during motion when the stability and smoothness of the capacitance and position data stored in BCS100 are poor. At this time, please redo the capacitance calibration until the stability and smoothness are good or excellent.

The "following gain coefficient" can be appropriately reduced since there is a lot of interference present in the field.

2) There are collisions with the surface during following motion.

The calibration range is set too small or the Z-axis speed is set too large

A small calibration range means a small deceleration distance during following. The speed may not reach 0 when the Z-axis moves to the target if Z-axis speed is set too high, causing overshooting. The larger the Z-axis speed when reaching the target, the larger the overshoot. It is recommended to set the calibration range to 15mm when the Z-axis speed is greater than 100mm/s. 20-25mm when greater than 250mm/s.

The servo rigidity is set too small

Setting the servo rigidity too low can cause servo response to lag behind the controller's signal, resulting in collisions with the surface.

Capacitance calibration

When there is a significant deviation between the capacitance stored in BCS100 and the actual capacitance being measured, it may cause collision with the plate during movement. The reason may be that the nozzle temperature rises abnormally high or the connection is not firm. At this time, first find the cause of the problem and solve it, then recalibrate the capacitance.

Locking nut of the ceramic body is not tightened

It may cause the capacitance to be unstable if the nut is not tightened.

3) The follow height is inconsistent with the actual set height.

Calibration issue

The above phenomena may occur if the capacitance calibration of the cutting head is not redone after replacing the nozzle.

Laser scattering onto the nozzle, abnormal blowing, etc. may cause the nozzle temperature to rise abnormally (above 100℃), which changes the local capacitance of the cutting head.

During intelligent calibration, the plate is not touched and the actual follow height is higher than the set value.

4) The lifting height is abnormal

When cutting, the lifting height is getting lower and lower. At this time, pay attention to whether the machine is slipping or the mechanical connection is not normal.

5) When upgrading, it prompts "verification error, ARM upgrade failed"

The file to-be-upgraded may be infected by a virus.

6) When the cutting head is calibrated, it lifts up without touching the board surface

The hit-board capacitance setting is incorrect. Be sure to set the hit-board capacitance to 0 when calibrating metal materials.

The latter one is the fine-tuning distance parameter, which can move the graphs quickly by using direction keys. The final show is the type of control card.

The rectangular area at the right of the interface is called “Console”, and most common operations related to control will be done here. From top to bottom are choices of coordinate system, manual control, work control, processing options and processing count.

7.3.3

Toolbar

The toolbar of CypCut adopts a style called Ribbon. It puts the common functions by column and area, and also applies many large-size buttons for easy operation. The photo below will help

you to understand this new toolbar:

The whole toolbar is divided into four “pages”, which can be selected by four menus “Home”, “Draw”, “CNC” , "Nest" and “View”. The related page will appear when selecting one menu. Furthermore, the page “Being Processed” will appear during processing and it cannot be switched to other pages before stopping.

The toolbar of each page will be arranged again in multiple “Columns” according to the functions, such as “Base operation” and “Geometric transformation” and so on. Generally, the first buttons of the columns are all in large size, and there is a small button“ ” at the lower right corners of some columns, which is called “Extending Button”, and a related dialog box can be opened by clicking this button.

Note: there are small triangles below some large-size buttons, which are called “Drop-down Buttons”, a related “Drop-down Menu” will appear after pressing the button, and the menu can offer richer operation options. When the mouse is moved to the top of the button, two obviously different rectangles will appear, the corresponding function of the button can be directly executed by pressing the upper part of the button, while a menu can be opened by pressing the lower part of the button.

You may have been very familiar with this arrangement if you have used Office 2007, Windows 7 or other procedures which use the Ribbon style before. It does not matter even if you use it for the first time, and we are sure that you will like this style soon.

7.3.4 File Menu

There is a special menu called “File” at the upper left corner of the toolbar, and it contains some menu items related to the files. The menu can be opened by clicking the button “ ” as shown below:

Please note that at the right of the menu the recently used files are listed. While the files saved by CypCut are marked with the icon“ ”, and in this way it is convenient for you to find the designed documents of last time.

The "Save as" in the menu can be used to save the file in LXD or DXF format.

The “Import” in the menu can be used to import another document to the drawing board without clearing the existing graphics. Please directly use “Open” if you just would like to open an external file.

CypCut V712.6 and later version can be used to open files in NRP and NRP2 formats exported by CypNest.

The "Report" in the menu can be used to export processing report, nest report and machine operation report.

The menu “User Parameters” is used to set some parameters related to the using habits; and the menu “Backup Params” is used to backup all parameters as a compressed file; and the menu "BCS100 monitor" is used to monitor and display the interface of BCS100 height controller in the software; while the menu “Diagnosis” is used for program diagnosis and monitoring.

You can see the detailed version information of CypCut software by clicking “About” at the lower right corner.

7.4 Operation Process for CypCut

draw pictures with the buttons of the drawing toolbar at the left. See the details in related chapters.

7.4.2

Preprocessing

When importing the graphics, CypCut will automatically remove trivial and duplication, combine near as well as automatically smooth, sort and de-group. Generally, you can set technicalparameters without other handlings. If the automatic processing cannot meet your requirements, open the menu “File”-“User Parameters” for setting.

Generally， the graphics to be processed are closed curves. Therefore, if the files opened include unclosed curves, the software will prompt and the unclosed curves will be displayed in red. However, this function may be closed. Thus, if you would like to look over the unclosed curves in the drawing board, click the buttons “ ” and “ ”under menu “View” in the toolbar to highlight them. You can also click the big button “Select” at the leftmost side of the toolbar, and then click “Select Unclosed Curve” to choose all of them.

In some cases, you need split the graphics manually, please click the button“ ” under “Optimize” in the commonly used menu and then click the mouse in the position where you need to split. To merge the graphics, please select them and then click the button " Combine near".

7.4.3

Technical Design

In this step you may use most of the functions in “Technical Design” in the commonly used

menu, including lead lines, compensation and so on. Big size button “ ” can be used to set lead lines, and the button “ ” is used to set lead seal over, lead seal gap or lead seal parameters. The button“ ”is used for cutting compensation; the button “ ” can insert micro joint of not cutting into the graphics; the button“ ” can reverse a single graph; and the button " " is for setting a cooling point in the graph. Click the button“ ” and then click the position where you hope to set as the start of the graphics, in this way you can change its start; if click outside the graphics, and then click on it again, you can draw a lead manually.

Press Ctrl+A to select all the graphics, then click the button “Lead” and set the parameters of the lead lines, and then click OK. In this way the software can search suitable positions to add the lead automatically according to your settings. You can conduct the "Lead Lines Check" by clicking the small triangle below the button “Lead” and selecting “Check lead lines”. When select “Distinguish inner and outer mold”, lead can be automatically optimized according to inner and outer mold. Set detailed cutting technical parameters by clicking the button “ ” in the toolbar at the right. The dialog box “Layer Parameter Settings” contains almost all the parameters related to the

cutting effect.

7.4.4

Lead Planning

In this step the graphics will be sorted as required. You can conduct automatic sorting by clicking the button “ ” under the “Home” or “Nest” menu, while you can select the ways of sorting and whether it is allowed to change the direction of the graphics and automatically distinguish inner and outer mold during the automatic sorting by clicking the small triangle under the button.

If the automatic sorting cannot meet the requirements, click the button“ ” in the toolbar at the left to enter the manual sorting mode, and click the graphics with mouse one by one, and in this way you can set the working order . You can specify the order between these two graphics through pressing the mouse and drawing a line from one graph to another.

You can fix the order of sorted graphics by selecting them and then clicking “ ” button under “Home” or “Nest” menu. The following automatic sorting and manual sorting will not influence the graphics inside the “Group”, and the “Group” will always work as a whole.

You can conduct automatic sorting for the graphics within the group by selecting a “Group” and then clicking the right key with selecting “Group Sort”.

7.4.5

Inspection before Processing

Before actual cutting, check the working route. You can align graphics by clicking align button; view the processing order quickly by dragging the interactive preview progress bar under “Draw”

menu as shown below; and view the processing order of the graphics by clicking the interactive preview button.

You can simulate process by clicking the button “ ” on the console, and adjust the speed of the simulation processing through the function “simulation speed” on the page“ ”.

7.4.6

Actual Processing

Please note that this step must be done on the actual machine with the support of dongle and the control card.

Before formal processing, match the graphics on the screen with the machine. You can find the positional relationship between the upcoming processing graphics and the machine breadth on the screen by clicking the left button“ ” above the “Console”.

This corresponding relationship is calculated in accordance with the dock point markers on the screen and the position matches of the machine laser head. Some common coordinatemarkers on the screen are shown in the photo below. Click “Preview”, the “Dock Point” will be moved to the “Laser Head Position” and visually parallel move occurs in the graphics on the whole.

Please check whether the position of the machine origin is correct if the “Laser Head Position” shown by the red cross cursor does not match the actual laser head position of the machine, and it can be corrected through “Numerical Control” “Go Origin”. After previewing, if you find that the graphics are outside the machine breadth wholly or partially, it means that it may exceed the range of travel during processing.

You can change the relative relationship between the graphics and the dock points by clicking the button “ ” under “Home” menu. For example, if the laser head is at the lower left corner of the upcoming processing workpiece, you can set the lower left corner as the dock point and so forth.

If there is no error on the screen after checking, click the button “ ” on the “Console”, and the software will control the machine to go around the outer frame of the upcoming processing graphics so that you can check whether the working positions are correct. You can also click the button“ ”, and the machine will run completely without laser along the graphics which will be processed so that you can check more carefully whether there may be any

impropriety in the processing.

Finally, please click the button “ ” to start the formal processing, and click the button“ ”to suspend the processing. During the suspension, you can control the laser head to go up and down manually, and switch the laser, gas and so on manually, besides, you can also trace back along the working route through the buttons “ ”. You can continue to work by clicking the button “ ”.

Click the button “ ” to stop the processing and the laser head can automatically return to the point according to your setting. As long as you do not change graphics or start new processing, when click the button “ ”, the system will locate to the position stopped last time; when click the button “ ”, the system will continue the processing from the position of last stopping.

8 Graphic Operation

8.1 Graphical Display

“View" in the first column under “Home” menu has multiple buttons which can help to control the display effect, as shown below:

After clicking the buttons in the figure above, the display will take effect immediately and then you can find the changes in the display effect in the drawing board. Please pay attention to the display changes of the buttons themselves, if the ground color is light yellow, it shows that the corresponding effect has started; otherwise, it indicates that the display effect does not start yet.

For example, in the on- state “ ”, the arrow will show the graphical processing path in the drawing board; while in the off state “ ”, the arrow will disappear.

You can clearly see the location of micro joints (white rectangular marks) on the graph by turning on "Show micro joint marks", as shown below:

When a graph is selected, click the button “ ”, and the graph will be shown in the center of the screen. If no graphs are chosen, click the button directly, and the whole graphs will be displayed in the center.

After clicking the button “ ” in the lower right corner of the column, a dialog box will be opened, and you can conduct more detailed control for the drawing board, including turning on and off the auto attach key-points, turning on and off the ruler and controlling the pick precision of mouse.

The views can be zoomed by scrolling the mouse wheel in the drawing board. By clicking F3, all the graphs will be shown in the center of the screen. By clicking F4, the machine breadth rangewill be displayed in the center. The above operations can be enabled by right-clicking the mouse with selecting “Zoom” in the drawing board.

8.2 Selection of Graphics

CypCut offers a variety of graphical selection methods. The basic operation is “Click Selection”, and the graphs will be selected just by clicking the mouse on the graph. Another one is “Box Selection”; by this way, a translucent box can be formed by dragging the mouse in the screento select the graphs. There are two kinds of box selection. When dragging the mouse from left to right, it shows a blue translucent rectangle with solid line and only the graphs covered completely

in the rectangle box can be selected; when dragging the mouse from right to left, a cyan translucent rectangle with dotted line will appear and as long as any part of the graph is in the box, the graph will be selected.

The schematic diagram of these two options is shown below. The left one is the option from left to right and BC will be selected; while the right one is from right to left, and ABCD all will be selected. Flexible use of these two methods can help you to choose the graphs in a more convenient way.

No matter it is “Click Selection” or “Box Selection”, if you press “Shift” while selecting, you can add or cancel selected graphics without clearing the original selection. Click the "Select" button, and a drop-down menu will appear, which allows for advanced selection, including:

1. Basic operations: Select All (Ctrl+A), Invert Selection, Copy (Ctrl+C), Paste (Ctrl+V), Cut (Ctrl+X), Cancel Selection (click on the blank area), Copy with Base Point (select a point, when pasting, the position relationship between the graphic and the cursor is the same as the relationship between the base point and the original graphic).

2. Graphic operations: Select unclosed graphic, select similar graphic, select all outer or inner mold, select all graphics smaller than the specified size (need to enter the size in the

drawing information bar).

3. Layer operations: Select layer (used to select all graphics within a layer), lock background.

4. After selecting "Disable quick drag and copy", users will no longer be able to drag, copy, or rotate graphics, thus avoiding the misplacement of graphics that have already been arranged due to accidental operations.

Among them, “Select similar curve” allows you to select all the graphics which looks close to each other on the drawing board. For example, you may select all the circles with a diameter of 5mmm by selecting a circle with a diameter of 5mm and then clicking “Select similar curve”.

8.3 Geometric Transformation

The column “Geometric Transformation” under “Home” menu provides abundant geometric transformation functions. Select wanted transformation graphics before applying. Most of the commonly used geometric transformations can be completed only by clicking the drop-down triangle under “Transform”, for examples: Mirror, Rotate, Align and Scale.

8.3.1

Size Modification

CypCut provides 7 fast size transformations, which can be completed by the drop-down menu below the button “Scale”. Click the small triangle under "Scale" button, you can open a drop-down menu, which provides selected graph operations of size transformation, as shown below.

For example, "100mm" will scale the graphics proportionately to a width of 100mm, and "2" will proportionally enlarge the graphics to 2 times its size.

If you want to input precise dimensions, simply click the "Size" button, and the following dialogue box will appear. Input the new dimensions and click "OK" to complete the size transformation.

When the status of lock on the interface is , the length and width are locked as the proportion of the original graphics. If you want to separately input length and width, cancel the lock status by clicking the button , and then the button will become

“Zoom Center” can determine the location relations between the new graphics and original graphics after being zoomed. For example, when you select “Upper Left”, it means that the new graphics and original graphics are aligned in accordance with the upper left corner after the transformation, and other parts are zoomed by taking the upper left as a basis.

Note: The lead and slotted compensation set for graphics cannot be transformed at the same

time, and the numerical value of lead and slotted compensation will not change after the size is changed.

8.3.2 Interactive Geometric Transformation

CypCut provides 3 kinds of interactive geometric transformation, including interactive zooming, rotation and mirror, by which you can achieve more detailed geometric transformation. Before doing these operations, firstly select the graphics, click the corresponding menu or button, and then conduct operations in accordance with the tips at the bottom of the screen.

For example, if you want to rotate a rectangle 45° by taking its lower left corner as a basis, operations are as follows:

1. Firstly, select the rectangle;

2. Click the small triangle below the “Transform”, open the drop-down menu, and select “Rotate”, and then there will be a prompt “Please Specify Base Point” in the lower part of the screen;

3. Move the mouse to the lower left corner, and then the mouse will be automatically absorbed to the lower left corner. As shown below:

4. Click the mouse, and then there will be a prompt “Specify Start Point of Rotation or Input Rotation Angle” at the bottom of the screen;

5. Input 45 and then click Enter.

If you do not know the angle but want to rotate the rectangle to the position aligning with another graphic, then the first four steps are the same as above, please conduct the following operations from step 5:

6. Move the mouse to the lower right corner of the rectangle, click to form a horizontal line and take it as the start line of rotation.

7. The screen shall prompt “Please Specify End Point of Rotation”. Then the graphics will rotate with the mouse, and you can complete the operations by clicking the mouse at the expected end point of rotation. As shown below:

The operations of interactive zooming and mirror are similar with this, so there is no further explanation.

8.3.3 Quick Translation and Copy

CypCut software allows you to use the arrow keys to quickly pan the graphics. To use this

function, click the "Move Distance" button in the lower right corner of the software interface to change from state to state. Only in the lighted state can the box on the right be edited.

After "Move Distance" button is turned on, select the graph and press any direction key, the graph will translate a distance in the corresponding direction. The distance parameter is input in the number box on the right side of the "Move Distance " button.

This function can help you temporarily move a graphic quickly, and then focus on the design of other graphics, and then quickly move back to the original place. Since the fine-tuning distance can be precisely controlled, there is no worry about the deviation of the graphic position. Press thearrow key while pressing Ctrl, the selected graphics will be copied. For example, pressing "Ctrl+Right" will copy the selected graphic at 100mm from the right.

8.4 Input of Coordinates and Parameters

In some cases, drawing with precise coordinates is needed. CypCut allows you to input the coordinates directly and its input format is as follows: <X coordinate><comma,><Y coordinate>. For example, to input the coordinates (100, 100), input “100, 100”. And the inputted coordinates and parameters will be shown in blue.

Most of the drawing operations allow both mouse operation and inputting coordinates directly.

Below is an illustration for drawing a rounded rectangle with a length of 300mm, a width of 200mm and a fillet of 50mm.

1. Click the icon “ ” on the left toolbar, and then “Please Specify Start Point” will be prompted.

2. Input the coordinates “0, 0” and press Enter, and then “Please Specify Cross Point” will be shown on the screen.

3. Input the coordinates “300, 200” and press Enter, and then “Please Specify Corner Radius or [Fillet (F)]” will be shown on the screen.

4. Input 50 and press Enter. All the operations are completed, as shown below

8.5 Automatic Adsorption

CypCut provides automatic adsorption during drawing, including automatic adsorption to the grids, adsorption to the critic points of the graphics, adsorption to the borders of the graphics and so on.

To close automatic adsorption, click the menu “ ”, select “User Parameters”, then select the tab “Drawing Board” in the opened dialog box, and finally cancel the option“ ”. The precision of automatic adsorption can also be set in the above dialog box.

8.6 Graphic Drawing

CypCut provides graphics drawing functions, in the left toolbar, from top to bottom: isolated point, straight line, polyline, circle, arc, rectangle, polygon, text, standard parts, also appearing in the drawing module of the upper menu bar. Among them, the last 2 are removed, and the first 7 functions are standard graphics drawing, which are similar to CAD functions.

8.6.1 Standard Graphics Drawing

The operations of isolated point, straight line, polyline, circle, and rectangle are simple and clear, and will not be repeated here. There are 2 functions in the drop-down menu of "Circle" in the "Drawing" column: "Replace circular positioning holes with isolated points" and "Replace with circles". The former can turn smaller circles into isolated points, and the latter can convert graphics similar to circles into circles, which is convenient for subsequent fly cutting.

Click the triangle below the polygon function for rounded rectangle, polygon and star. For rounded rectangle, draw a rectangle first, and then determine the rounded corner radius by moving the cursor, or directly enter the rounded corner radius in the drawing information bar. Both polygon and star need to specify the number of sides (3 to 100). The polygon is a regular polygon which can be rotated. The number of sides of the star is the number of its vertices. For example, the six sides are the six-pointed star. In addition, in the drawing module, in the drop-down menu of "Rectangle", there is an additional "Raceway Shape" function, which is the same as the drawing method of a rectangle. You can add semicircles to the left and right sides of the rectangle to generate a runway shape.

8.6.2

Text Input

CypCut supports text input and text conversion to curve. After clicking the button “ ” on the drawing toolbar at the left, insert text in the desired position by clicking the mouse and the newly inserted text will be selected automatically.

After selecting the text at any moment, a new page “Text” will appear in the toolbar, in which you can modify the content, the style and the size of the text. As shown below:

Please note that once the text is converted to the curves, the above option cannot be used any longer. To design a text with specific font and special effect, please convert it to curves after you design it well.

8.6.3

Draw Standard Part

CypCut provides drawing of standard parts. Click the " " button on the drawing toolbar on the left to draw commonly used parts. After selecting the part type, set related parameters on the next page. As shown below:

8.7 Measurement

CypCut provides tools for measuring the distance between two points. Click the "Measurement" button in the "Tools" column, then select a point on the drawing, drag to display a guide line, and then select another point, and the drawing information column will display the positional relationship between the two points.

8.8 Graphical Optimization

When importing the external graphics, CypCut can optimize it automatically. To optimize them manually, use the "Optimize" functions in the toolbar. As shown below:

Select the graphics to be processed and then operate according to the prompts.

8.8.1

Smooth

Select the polylines to be optimized, then click " " button, a prompt “Smooth the selected curve according to a given precision” will be shown on the dialog box. Please input the expected curve smoothing precision and then click OK.

The contrast between the original curve and the smoothed curve is as shown below. In order to facilitate the observed effect, the curve smoothing precision value entered here is greater. Please use the actual value according to required processing precision.

8.8.2

Split

Split is to divide the closed graphic into two graphics and the user can edit these two graphics separately. Please click the button “ ”, and then click the mouse in the position where you need to split. The process of curve split can be carried out continuously as far as click ESC to

cancel the command or it is switched to other commands.

8.8.3 Remove Tiny Objects

Sometimes the imported graphics may include the curves that are visually imperceptible, which causes the display size to become very small, or move to an abnormal position when processing. These graphics can be deleted through the function “Remove trivial”. Click the button “Remove trivial”, set the size range of the graphics, and then confirm the operation. The graphics smaller than this size will be deleted and other curves will be retained.

8.8.4 Remove Duplicated Curves

This function is used to delete the visually overlapping lines and only leave one. You can search and clear all the graphics by clicking “Remove Duplication”.

8.8.5 Combine Near

The graphics drawn with AutoCAD often includes the graphs which connect visually while do not connect actually. Through connecting near, they can be combined. Please select the graphics to be merged, then click “ ”, input merging accuracy, and confirm the operation.

Note: The end points of the graphics in visual may be not the ones in geometric, and the

excess backtrack lines may exist in the end points. These graphics need to be split and deleted firstly through “Split”, and then can be combined.

8.8.6

Cut Up

To prevent material warping and poor machining, you can utilize the "Chop" function to generate white-colored chop lines within the "internal contour" graphics, which is distinct from theregular cutting graphics.

8.8.7 Cutter (Split Drawings)

To adapt to the machine tool, the entire drawing can be divided into several parts for cutting. Divided drawings need to be saved separately, shown in red borders.

8.9 View

The view module can adjust the zoom, display position and order of the graphics, and can also edit the graphics. The function entry is located above the left toolbar, and from top to bottom are selection, node editing, manual sorting, panning view and zooming.

8.9.1

Node Editing

CypCut provides a node editing mode for fine-tuning graphics. Select "Edit Node " and then select the graph to see the distribution of nodes. Drag a node (yellow and blue rectangle points as shown in the figure below) to adjust the graph. Click the "Select " button again to exit the node editing mode.

Yellow represents nodes and start points, blue represents nodes, both are draggable.

9 Technical Design

This chapter describes the functions of technical parameters provided by CypCut. Because most of the technical parameters have direct relations with the materials to be cut, the used laser source and air pressure, you need to set the parameters according to the actual technical requirements. All the parameters mentioned here including the ones in the graphics should only be used as examples rather than being considered as guidance parameters.

Warning! Please set the parameters carefully because the inappropriate or incorrect parameters may result in poor cutting effect or even damage to the machine.

9.1 Lead Lines

9.1.1 Distinguish Inner

and Outer Mold

When opening the external files such as DXF and so on, CypCut can distinguish inner and outer mold automatically. If the graphics are modified during editing and result in the changes in the relationship between inner and outer mold, you can click the button “Auto Sort” to distinguish them again. There are two ways:

Select “Distinguish inner and outer mold when sorting” located at the drop-down menu of “Auto Sort” with default selection.

Click drop-down triangle button of "Lead" and select "Distinguish inner and outer mold".

CypCut distinguishes inner and outer mold in accordance with the surrounded relations, and it always takes the outermost layer as outer mold, while the next one as inner mold, then outer mold and so forth. Besides, an unclosed graphics cannot form a layer. To start outer mold from a certain layer, choose all the graphics from this layer and inside it, group them, and then distinguish inner mold and outer mold through “Group Sort”.

When adding lead lines, the external layer is yang cut, so it will be led in from the outside; the internal layer is inner mold and will be led in from the inside. When set inner and outer mold manually, please select the graphics to be set, and then click the buttons “ ” under “Home” menu.

9.1.2 Automatic Lead Lines

Please select the graphics to be set with lead lines, click the icon “ ” under “Home” menu, then set the lead lines parameters in the popped window. As shown below:

The lead types include Arc, Line and Line + Arc, while the parameters consist of lead type, lead angle, lead length and lead radius. You can also choose whether to add small holes at the starting point of Lead lines.

When you select arc leading, the end of the circular arc needs to keep in tangent with the graphics to be cut (no matter how big the set angle is). As shown below. In fact, the set angle is an included angle between the connecting line of the start point and the end point of the lead line and the graphics to be cut. The lead out line is similar to it.

Please note that when automatically selecting the lead-in position, the system will determine it based on the predefined priority vertices or priority long edge of the graphics. As a result, the previous lead-in position, type, and other parameters of the graphics will be overwritten. If you have specific requirements for the lead-in position, you can set a uniform position based on the total length of the graphics or keep the lead-in position unchanged while only adjusting the type option.

9.1.3 Manual Lead Lines

To modify the lead line manually, click the button “ ” on the toolbar. If click on the graphics, you can change the position of the lead lines. However, the angle and the length can't be modified.

Firstly, please click (point A, yellow point) outside the graphics, then click (point B, red point) on the graphics, in this way you can draw a lead line from point A to point B.

9.1.4 Check the Lead Lines

Click the small triangle below the button "Lead", and then select “Check Lead” to check the validity of the set lead lines. This function can shorten the lead lines with too much length, and thus prevent them from intersecting with other graphics. Click "Distinction inner and outer mold", you can determine the specific lead position according to the set inner and outer mold.

9.1.5 Lead Seal, Gap and Over

There are three buttons, as in “Technical Design” under “Home” menu. Please select the graphics to be set, and then click the corresponding buttons. The size set of “Gap” or “Over” can only be valid when resetting gaps or over cut later, and the size which has been set before will remain unchanged.

9.2 Cutting Compensation

Please select the graphics to be compensated, and then click the button “ ” on the toolbar for cutting compensation.

The cutting width will be obtained in accordance with the actual cutting results. The compensated track will be shown in white on the drawing board and the system will run along the compensated track during processing. The compensated original drawing will not be processed but will be displayed on the drawing board.

The direction of cutting compensation can be selected manually. It can also be judged automatically according to outer mold or inner mold. Outer mold needs outward compensation, while inner mold needs inward compensation.

During cutting compensation, you can translate the corner in the form of round angle or right angle. As shown below:

In the figure the green is the original, the white is the compensated track, and the light yellow is the vertical lines drawn from the corner. The cutting edges can coincide with the original after both sides of the vertical lines are compensated, while the corner needs transition. Usually, round

angle transition can ensure that the cutting edges can still coincide with the original and ensure smooth transition.

You can edit the common compensation value in the general configuration.

To clear compensation, please select the needed graphics, then click the button “Clear” and choose “Clear Compensation”, or directly select the "Cancel Compensation" button under Kerf Compensation.

9.3 Micro Joint

“Micro Joint” is used to insert a micro joint which will not be cut into the track. This function can prevent part warping. When cutting here, the laser will be closed; however, whether closing the gas and the following is determined by the parameters of short-distance moving during cutting. Micro joint is shown as a gap on the drawing board. As shown below:

Click the button “ ” on the toolbar, add a micro joint by clicking at the position in the graphics needed. You can insert multiple micro joints by clicking continuously until pressing ESC to cancel the command or switching it to other commands. You can insert micro joints by clicking on either the graphics or the compensated trajectory.

Please directly enter the length of the micro joint in the drawing window at the bottom of the interface, and the new parameters will be valid for the following operations after setting.

Except adding the micro joints manually, CypCut also can insert micro joints automatically. Click the “ ” button by clicking the small triangle button in the right corner of "MicroJoint", set the parameters in the popped dialog box, and then confirm it. You can select “adding byquantity”, for example, add ten micro joints to each graphic; or “adding by distance”, for example, insert a micro joint every 100mm.

The graphics may be divided into several parts by “Micro joint”. To modify the separated part alone, click the "Explode Micro Joint" button under the "Micro Joint" drop-down menu. Unclosed graphics after “Micro Joint” operation will be regarded as a separate entity for modification. "Explode" the micro joint and then you can add the lead line.

To clear the micro joints, select the needed graphics, then click the “Clear” button and choose “Clear Micro Joint”.

CypCut V731 introduced "fly cutting" for micro joint segments. It involves turning off the laser when moving to the micro joint's starting point, moving without laser until reaching the end, and then turning on the laser. There are no acceleration or deceleration processes, and the Z-axis remains unchanged. This method greatly improves efficiency in cutting micro joint section.

9.4 Cooling Point

Click the " " button in the “Home” menu. Set a cooling point by clicking on the corresponding position in the graphics. When cutting is implemented to the cooling point, laser will be off and blow will be delayed according to cooling point settings in the global parameter. Later,

laser will be on and operate normal cutting. Cooling point is displayed as a white solid point in the drawing board, as shown below:

Multiple cooling points can also be inserted by continuous clicking as well as Micro Joint. Cooling points can still be added after operating micro joint, compensation and so on.

CypCut offers an automatic cooling point feature in addition to manual ones. To use it, click the "Cooling Points" button and select "Automatic Cooling Points" from the dropdown menu. Set the parameters in the dialog box and confirm. Automatic cooling points can be added at lead points and sharp corners. If added at the end of a lead line, they become part of the line and move or delete accordingly. Also, they are not affected by the "Clear Cooling Points" function.

To delete a cooling point, Shift-click on it. To remove all cooling points, click the small triangle next to the "Cooling Points" button and select "Clear Cooling Points".

Cooling points are often used in corner processing to briefly pause and blow air to cool down the corner, preventing it from burning.

9.5 Ring Cut

After selecting the graphic, click the " " button on the toolbar to achieve better sharp corner cutting effect.

9.6 Fillet and Relief

Click the " " button on the toolbar to convert sharp corners into rounded corners.

Click the " " button on the toolbar to generate relief angles, which are helpful for the next bending process.

9.7 Group

In CypCut, "Group" refers to combining multiple shapes or groups into a single group. The grouped elements maintain their fixed order, position, and layering within the group. This allows them to be treated as a cohesive entity, unaffected by sorting or dragging operations.

Select the graphics to be grouped, and then click the button “ ” to combine them to a group. To cancel the group, please click the “Group” button, which has changed to “ ”. To explode all the groups on the drawing board, please click the small triangle below “Group”, and then select “Explode Graphics”.

"Ungroup" does not separate individual curves but only breaks apart grouped elements, while "Explode" breaks a shape into individual line segments.

"Joint Path" connects part contours to minimize piercing. To separate them again, use the "Explode Joint Path" option.

If there is a graphic which contains all the other graphics in the group, it is called the outer contour. The “Group” with outer contour will be regarded as a “Part”.

It is recommended to group the graphics which meet the logical conditions of the “part” although CypCut software can group any graphics and operate them as a whole. From now on we may use these two terms “group” and “part” indiscriminately.

Please note that CypCut software will always group the graphics with “Coedges” to ensure the integrity. Furthermore, the result of bridging one “Group” with other graphics or “Groups” must be a “Group” to ensure the integrity.

9.7.1 Sorting of Group

The part will be regarded as a whole when being sorted, and it will be involved in sorting with the outer contour or the first graphic as the basis. The graphic order within the part will not change during sorting.

To sort the graphics in the group without exploding it, select the group, right-click, and then choose “Sort in Group”.

The operation of “Sort in Group” will not change the graphical order of its sub-group. The order of “Sort in Group” only has the relations with the geometrical properties of the graphics, while no relation with the layer to which it belongs. During the sorting, it will distinguish inner and outer mold automatically according to the geometrical containing relations.

9.7.2 Processing of Group

Groups (parts) are processed as a whole during machining, allowing for continuous processing without inserting other graphics. Even if a group (part) contains graphics from multiple layers, they are processed continuously. This rule also applies to pre-piercing in group.

Please sort before processing, because no matter what the graphical order in the part is, the outer contour of the part will always be processed finally.

9.8 Fly Cut

When the graphics to-be-cut are regular (such as rectangular, full circle, polygon) with a certain regular arrangement, you can connect the cutting line segment with same direction by scanning to conduct flight cutting, which will greatly improve the cutting speed.

It's recommended to sort graphics before scanning, which can optimize the path of scanning and save move time.

Click the " " button under “Home” menu (Note: this button functions as "Circle Fly Cut" when all the graphics in the rule array are circles) or select the "Linear Fly Cut" option from the dropdown menu to set its parameters.

The "Start Position" sets the starting point for scanning cutting. The "Max Smooth Joint" determines that when the turning distance is smaller than the set value, smooth connection can be used. The "Max Spacing" specifies the maximum allowable distance between graphics for flying cutting. If the spacing exceeds this value, flying cutting cannot be set.

For an array consisting entirely of circles, you can click the "Fly Cut" button for the Circular Fly Cut feature. Alternatively, select the "Circular Fly Cut" option from the dropdown menu of the "Fly Cut" button to access the parameter settings.

The "Max Spacing" determines the maximum distance between circles. If the spacing exceeds this value, flying cutting cannot be set.

The "Sort Orders" option enables sorting of circular arcs before flying cutting. When "Fly Cut by Part" is also selected, the sorting rules are applied for flying cutting within each part.

If you only select "Sort Orders," the shapes will be sorted as a whole before the flying cut is performed.

You can set the overcut distance in the global parameters for better part detachment during the flying cut.

9.9 Coedge

It can greatly save processing length and improve efficiency by merging the workpieces with the same edges. In CypCut, when the boundary distance between two graphics is less than 0.1mm, they can use the same edge. Automatic adsorption will drag these two graphics together for

coedge.

Select two or more graphics to be coedged, and then click the button “ ” on the toolbar to perform coedging If they cannot meet the conditions of coedge, the window “Draw” at the lower left corner of the interface will prompt a message.

At present, CypCut can only coedge the four sides of the graphics, and it cannot coedge the straight lines of the recesses in the graphics.

The graphics involved in coedge will form a “Group” after coedge. If they include other graphics such as small holes, please combine the graphics and all the interior graphics together toform a group firstly, then coedge them; otherwise, the relationship between the interior graphics and the coedged group will become meaningless, and it will be difficult to determine the

processing order and the relations of the internal and external contours.

9.9.1 Coedge Automatic Adsorption

When you drag a shape close to another shape that can be coedged, CypCut will automatically snap them together and provide prompts. This feature allows for easy positioning when dragging two shapes or a group of shapes together.

Once two graphics are dragged together and have the same edges, you can coedge just by selecting them and clicking the button “Coedge”. To disconnect and continue to edit the coedged “Part”, or set their order, please select “Part”, and then click “Degroup” under “Home” menu. You can combine them again using the button “Group” after editing.

9.9.2 Compensated Coedge

To retain kerf compensation after coedging, apply compensation to the shapes before performing coedging. In any case, “Coedge” will keep the processing track unchanged. If the

coedged graphics contain compensation, the compensated track will be retained after “Coedge” and the original will disappear. As shown below

In fact, in the figure above, the original A cannot be coedged with the graphic B, and only the compensated track P can be coedged with B. Even if you move B to the position near to A, you still cannot coedge them because A is not the track to be processed.

9.10 Bridge

To keep multiple parts of a workpiece connected after cutting and minimize piercing, use the "Bridge" function. By utilizing the "Bridge" feature repeatedly, you can achieve a continuous cutting path for all the shapes.

To bridge two graphics, please click the button “ ”, and then draw a line on the screen. And all the graphics intersected with it will be bridged together two by two. As shown below:

Bridge needs to specify two parameters. The first parameter specifies the maximum distance between two adjacent curves, and you can bridge them when the distance between two graphics is less than the specified parameter. The second parameter specifies the width of bridge.

Please note that the graphics will become a whole after bridging. Maybe any part will not be cut before completing the “One-stroke” cutting, so please pay more attention to the heat affecting.

9.11 Array

"Array" command can be used to copy an object quickly and accurately. CypCut provides four ways of array.

9.11.1

Rectangular Array

Click " " button or "Rectangular Array" under “Array” drop-down menu. Parameter interface appears as shown below.

Set the number of rows, columns, offset and direction to quickly copy the selected graphics, as shown below:

9.11.2 Manual Array

Click "Manual Array", set up the spacing of line and column, and you can designate the area by dragging the mouse to select the graphics for quick array copy. As shown below:

9.11.3 Circular Array

Circular array allows for quick rotation of shape around a central point.

9.11.4

Full Fill Nest

Full fill nest is mainly used for entire board cutting of single graphic, click "Full Fill", the

software will quickly perform Full Fill Nest according to given part, parameters and plate. See plate

setting in "Nest" section. The full fill effect is as shown below:

9.12 Batch Modify

Use the "Batch Modify" feature to streamline the modification of similar shapes. In the example given, select the shapes, enter the batch editing interface, set the lead lines, and apply them to both shapes simultaneously.

9.13 Layer Parameters

CypCut provides 16 layers and every layer can set separately technical parameters such as move speed, laser power, pressure, cut height and so on. The last two layers represent the initial and final processing layers, respectively.

Open the dialog box “Layer Parameter Settings” by clicking the button “ ” under “Home” menu. This dialog box includes almost all the technical parameters required for processing. The

first page is “Global Parameter”, used to control the parameters outside the layers, including motion parameters, default parameters of laser and gas, follow parameters and so on. Other pages in the dialog box display all the current layers. By clicking on each layer, you can individuallyset the process used for that layer.

Note: Different options may be displayed in the dialog “Layer Parameter Setting” due to different laser sources, gas pipeline configurations and height controllers. The above figure is for reference only. Please refer to the actual display in your software for accurate information.

9.13.1

Descriptions of Parameters

The brief descriptions of some parameters in the layers are as follows.

A. Basic Parameters

Cut speed Set the target speed of actual cutting. There are acceleration and deceleration at the first and last sections as well as the corners of cutting track, so the actual cutting speed is often less than this speed.

Lift height

Set the lift height of laser head after cutting a segment of curve. Z-axis will lift to a certain height after suspending the cutting, which is also lift height.

B. Cutting Mode

Standard Cut according to set standard parameters.

Fixed-height cut Cut with laser head at a fixed height.

Extra-plate follow When you select this mode, the knife point can be docked off the board. During actual cutting, portion of the laser head outside the plate will stay in the "Reference height", and follow cutting after detecting in the board, which is commonly used for cutting off metal plate.

The setting pattern of "Reference height" : Save the parameters by the path of "CNC" "BCS100" "save reference height when follow outside plate", when the laser head move to the appropriate height.

C. Cutting Parameters

Cutting height

Set the height from the laser head to the board during cutting.

Cutting gas Set the type of auxiliary gas used in cutting.

Cutting pressure Set the pressure of auxiliary gas during cutting, and use it with proportional valves or multiple valves.

Peak current Set the peak current of laser source, i.e., diode power. Peak power determines the maximum cutting power that machines can reach. As for a cutting machine with a power of 3000W, if its diode current is set to be 80%, the diode power it can reach during cutting is 3000W *80% = 2400W.

Duty ratio

Pulse frequency

Set the duty ratio of PWM modulation signal.

Set the carrier frequency of PWM modulation signal during cutting, i.e., the laser number within one second. The larger the value is, the more continuous the laser is.

Cut focus The distance between the focal point and the tip of the nozzle.

Duration Delay for material penetration in order to achieve more thorough cutting of the board.

Laser off delay Delay for ensuring complete cutting before laser off.

Piercing speed

Set the speed from piercing height slow down to the cutting height during progressive piercing.

Extra puffing Set time for puffing with laser off after piercing, to make the plate cool.

D. Other Parameters

Uncut The layer process is not processed.

Unfollow Height controller is not carried to follow motion when this layer is during cutting.

Keep puffing Keep puffing during cutting.

Short move un-lift After selecting this option, if the move distance between two graphics is less than the value of "Un-lift move distance less than" set in global parameter, then Z axis is not in elevation and directly moves to the beginning point of the next graphics to start processing, after the above graphic completes processing.

Pre-piercing Before actual cutting, piercing in advance at the beginning point of graphics (or lead starting point). CypCut provides auto group prepiercing. You can select this option in the global parameter. Note: This option is not available with "Cut with film".

Cut with film

You can use it to perform one time cut with film along the cutting path, and then perform normal processing according to layer parameters.

Afterselecting this parameter, "film layer" setting page will appear.

Path cool

Start length

After a single graphic normal processing, process one time with laser off and puff on along the original track, to accelerate parts rapid cooling andreduce the impact of thermal expansion and contraction effect on the accuracy of the workpiece. After selecting this parameter, "Cool layer" setting page will appear.

E. Slow Start

Set the length of slow start, to prevent cutting thick plate without completing at the beginning.

Start speed Set the speed of slow start

Adjust power/frequency in real time

F. Power curve

Customize the power/frequency curve. During processing, the system will adjust the laser power (duty ratio of PWM signal) and frequency in real time according to the curve, which is of great help to optimize the cutting quality of corners. Note: If you choose to adjust the frequency in real time, you must also choose to adjust the power in real time.

9.13.2 Dynamic Power and Frequency Adjustment

After selecting “ ”, the duty ratio and frequency will vary with the changes in speed during cutting, and the specific changes are determined by power and frequency curve. You can click “ ”button to edit power and frequency curve.

As shown above, the X-coordinate of power / frequency curve represents cutting speed, while the Y-coordinate represents cutting power / frequency, with a unit in percentage. You can add power points corresponding to the respective speeds and select the curve smoothing pattern. You can also click “ ” to copy the power curve as frequency curve. This table shows the required power/frequency reduction when cornering speed drops to a percentage of the

target speed. Note: Adjusting frequency in real-time makes sense only after selecting “Dynamic Power Adjustment”.

For example, if the laser power is 500W, cutting speed is set to be 100mm/s, peak current to be 90% and cutting power to be 80%, when the actual cutting speed drops down to 29mm/s, the power of laser source is as follows:

Laser power X Peak current (percentage) X Cutting power (percentage) X Speed following power (percentage) =500W X 90% X 80% X 79.00%= 284.4W

However, the power cannot be less than a pre-set minimum value. Generally, it is set to be 10%, i.e., 500W * 10% = 50W.

If “ ” is not selected, the power will remain unchanged in the cutting process. Referring the above example as a reference, the power in the cutting process is as follows: 500W X 90% X 80% = 360W

9.13.3 Layer Setting

You can lock or display a particular layer according to prompt by clicking drop-down triangle button of "Layer" under “Home” menu. If there are multiple layers when import DXF files, please click the "DXF Layer Mapping" to see the number of layers and the corresponding graphics. As shown below:

9.13.4 Lead Slowly

When processing thick stainless steel, perforation generates a plasma cloud that absorbs laser energy and reduces cutting ability. To address this, a special lead-in technique is used. After perforation, the cutting head blows away the plasma cloud at a higher position, while horizontal processing compensates for airflow loss by reducing speed. This ensures the material is cut through.

When cutting thick plates, lead parameters can be set separately in the layer parameters, including cutting speed, lead height and stable distance.

Lead line cutting procedure:

1. Execute a piercing action at the starting point of the lead line.

2. After piercing is completed, raise the tool to the height of the lead line.

3. Gradually lower the Z-axis to the cutting height while using the XY-axis to perform slow-speed cutting at the lead line's stable distance position.

4. Start cutting the desired path after cutting stable distance at the cutting height.

9.14 Nest

Nest function is used for reasonably arranging given parts on the plate. CypCut not only supports nest with one key, but also provides a number of optimization parameters for fine adjustments, such as: Gap, Plate Margin, Rotate Angle, Auto coedge, Create remnant and so on.

Click " " button in “Home” page or “Nest” page to achieve this function.

9.14.1 Nest Operation

After clicking Nest, the software shows a sidebar on the left with part library, plate library, and nested plates.

The part library shows part thumbnails for nesting. You can add parts by right-clicking on a selected shape and choosing "Add to Part Library," or by right-clicking in the left sidebar and selecting "Import Part." The part library supports up to 50 types of parts. Additionally, right-clicking in the left sidebar allows importing standard parts, deleting all parts, and saving un-nested parts.

The plate library shows types and quantities of plates. You can add plates by right-clicking on a selected shape and choosing "Add to Plate Library," or by using standard plates. Also, rightclicking in the left sidebar allows deleting all plates or saving them to a file.

Nested Plates shows the automatic nesting results. It indicates in the thumbnail if a material

has been processed or if the nesting results have been modified. The current algorithm supports a maximum of 20 plates for nesting.

For automatic nesting, parameters need to be set. "Parts Gap" determines the minimum gap between parts. "Plate Margin" specifies the border around the parts on the plate. "Nest Strategy" determines the algorithm used for calculating the nesting results. Currently, only the array strategy is supported.

In detailed settings, you can adjust rotation angle, layout direction, common edge, and remnant settings.

9.14.2 Nesting Report Preview

Right-click on the nested plate in the left sidebar, select "Report Information" to set layout and pricing details. Then, right-click again and choose "Generate Report" to open the process interface. Set basic processing information for price estimation, and view the report. Refer to the image below:

9.14.3 Auto-switch to Next Sheet for Nesting

After opening NRP or NRP2 (processing tasks generated by CypNest nesting software), all the nesting results will be listed on the left side, along with the number of completed and required processing cycles. The completed count increases by one after each processing cycle. Once the required number of cycles is reached, it automatically switches to the next drawing.

Supported version: CypCut V712.6 and above.

9.15 Sorting and Path Planning

Most of the path sorting functions can be found in the "Sort" section of the toolbar. As shown below:

As for the rules of group sort, please see the chapter “Group”. It is recommended to select “Grid Sorting” if there is no special requirement.

9.15.1

Order Preview

You can preview the processing order by dragging the progress bar “Graphical Order Preview” or clicking the button “ ”. The figure below demonstrates a screen when previewing the parts.

The order preview is fully interactive and it can be more easily controlled than simulation processing. You can zoom in and preview the desired location in detail. All the move paths will be shown by clicking the button “ ” under drop-down triangle button of "View" on the common toolbar to look over the whole processing order.

9.15.2

Manual Sorting

To fine-tune the results of the automatic sort, you can use the manual sorting. Firstly, select the graphics to be adjusted, and then click the buttons in the icon “ ”. The functions of the four buttons from left to right are as follows:

Note: no matter how you move the graphics, their order can only change in the layers to which they belong. The overall order between the layers can be adjusted in the dialog box “Layer Parameter Settings”. See the chapter 9.13 “Layer Parameters”.

Click " " to view the previous/next shape in the current sorting order.

Except fine-tuning, the manual sort can be performed more intuitively through “ManualSorting Mode”. Enter the “Manual Sorting Mode” after you click the button “ ” on the left toolbar of the main interface. The move path and the digital display of the graphical order will be opened automatically. Click on the shapes one by one to set the processing sequence. If you click in the wrong place, simply click again or right-click to cancel. To adjust the order between two shapes, click and drag the mouse from one shape to another in a straight line. See the figure below.

9.15.3 Partition Sorting

After completing sorting the order of one part, to fix it, you can select the graphics needed to fix the order and then click “Group”. After that, the order between them will maintain unchanged. Besides, the subsequent manual sorting and automatic sorting will not influence the interior of the

group. After grouping, all shapes within the group will be processed consecutively, without interruption from shapes outside the group.

To perform automatic sort for part of the graphics without influencing other parts, you can also complete it through grouping. Select the graphics to be sorted, right click “Group”, and then select “Sort in Group”.

10 Work Control

CypCut is a software that combines design and machining control. You can prepare all the shapes and parameters separately from the machine. Once the design is complete, you can save the file and open it on the machine for cutting.

10.1 Coordinate System

The “Model Coordinate System” used in the graphical design has no relation with the machine, and its zero point is marked by “ ” on the screen. However, the coordinate system used in the processing is related to the operating status of the machine. The correspondence of these two coordinate systems is shown as below.

The positional relation between the graphics and the machine tool breadth will be displayed on the screen after you click the button “Preview” on the console.

10.1.1 Mechanical Coordinate System

The mechanical coordinate system is uniquely determined by the machine structure and the machine parameters. At any time, all the coordinate systems set through “Go Origin” are consistent with each other. You can reset the mechanical coordinate system by clicking “Go Origin” in the “CNC” page after completing the initial installation or when the mechanical coordinate system deviates abnormally.

No matter which kind of mechanical structure is used, the definitions of CypCut for the coordinate systems are always consistent with each other. All the moves are that of the laser head relative to the workpiece. If the laser head is rightward, it is X positive direction; however, if the laser head is backward, it will be Y positive direction. That is to say, the lower left corner of the workpiece (steel plate) is the minimum coordinate, while the upper right corner is the maximum coordinate.

10.1.2 Program Coordinate System

Because the coordinate system of machine tool is fixed, workpiece coordinate system is needed for convenient use. The direction of each coordinate axis of all the program coordinate systems in CypCut is fully consistent with the machine coordinate system. Only the zero point of the coordinate system is different, which is called Program Zero Point. The program coordinate system is divided into the floating coordinate system and the workpiece coordinate system.

The button at the top of the console can be used to select the program coordinate system, including "Floating Coordinate System", 9 “Workpiece Coordinate Systems” and 1 “External UCS”.

Usually, the floating coordinate system is used for informal processing, and it can be considered that “Where the laser head moves, it will start to work from there”. The zero point of its coordinate system is automatically set as the current position of the laser head when users click “Walk”, “Dry Cut” or “Work”.

When selecting the workpiece coordinates 1~9, its zero point will be set manually through “Set the Current Point as the Zero Point”. Once set, it will be saved until you reset it next time. Thus, the workpiece coordinate system is suitable for bulk production, and its location is generallydecided by the fixture. It can be maintained that every processing will be performed in the same position of the machine by using the workpiece coordinate systems 1~9.

Click status bar " "at the bottom. You can choose to "Show Mechanical or Program Position". You can also set zero here of the two coordinates. If you select "coordinate positioning", laser head will be positioned to a specified coordinate position.

10.1.3

Searching Zero Point after Exception

Case one

You can click directly “ ” to go to the zero point if the processing is interrupted only due to the exception of external equipment such as the laser source and auxiliary gas device without any coordinate system offset.

Case two

If the mechanical coordinate deviates due to suddenly power failure or servo alarm, it is recommended to perform “Go Origin” and reset the mechanical coordinate system, then click “ ” to find the zero point.

Case three

If processing is forcibly interrupted, but the start button was mistakenly pressed, you can find the previous zero point of the last processing by selecting 'Memory Zero Point' from the dropdown menu under the mark coordinates in the control panel, and then clicking 'Go Marker'. Supported in CypCut V731 and above versions.

10.2

Alarm

CypCut will monitor all the parts during the running of the machine. If an alarm is detected, it will display immediately the alarm in red title bar and take measures such as stopping the motion. Before the software alarms are removed, many operations will be forbidden, and please check the machine and operation again after the alarms are canceled. One example of the alarm is as shown

below.

Except the title bar, the “Alarm Window” at the lower left corner of the interface can also display the alarm information. After the alarms are removed, the red display will disappear, however, the information in the “Alarm Window” will be retained. You can look over all the history by double clicking “System Window”.

In addition to alarms, CypCut displays other operational abnormalities in the "System" window with different colors based on their severity, including warnings, reminders, and messages. These won't stop the machine but it's important to promptly check the software for any displayed messages and take necessary actions early on.

Alarms can be automatically or manually cleared. Check the option to manually clear all alarms under "Process-Global Parameters" in the bottom right corner.

Here are some limitations associated with certain alarms:

1. After an emergency stop, the servo enable is cut off to prevent unintended power supply.

2. The alarm of height controller prohibits XY movement (Note: The status of the Z-axis is unclear, and there is a risk of collision during XY movement).

3. After an emergency stop, the Z-axis is also disabled from moving (entering a complete stop state).

4. Z-axis lower limit alarm prevents jogging or rapid movement (similar to point 2, to prevent collision).

5. After the height controller alarm, it can be configured to require manually clicking the 'Allow Axis Movement' button to resume movement

Instructions for use (Version support: CypCut V731 and above):

1. Check the "BCS alarm must be acknowledged" and " Force enable manual reset" options in the "Alarms" tab of the platform configuration tool, and save the settings.

2. If a height controller alarm occurs, you will see " Axis Movement" and " Alarm Reset" buttons at the bottom right corner of the interface. Click the " Axis Movement" button to control the machine movement.

10.3 Manual Testing

The functions of the manual control on the console are shown in the following figure:

The button with the icon“ ”will become“ ”after the corresponding equipment is opened. Press the button “ ”to turn on the laser, and release to turn off. The other buttons toggle on when pressed and do nothing when released. Taking button “ ” as an example, blowing will start after pressing the button, and stop after pressing the button again. According to different laser sources, the" " may become “ ” after pressing the button and this state is read from the laser source. " " activates the laser source to emit red light.

Note: all the button actions need the support of the corresponding parts on the machine. If the machine is not equipped with these parts, or the platform parameter configuration is incorrect, some buttons may become invalid.

The current position of the machine tool can be recorded by clicking “ ”, and the

machine can return to the previously recorded position by clicking “ ” if required later. Six positions can be recorded in total and they will be selected through “ ”.

10.4

Soft Limit Protection

To protect the machine, CypCut is installed internally with the soft limit protection, which can be turned on and off through the option “ ” on the console. It is enabled by default.

After the soft limit protection is enabled, if the software detects that the motion may exceed the travel range, it will prompt “Motion is Out of Range”, and will not issue any motion commands to avoid the possible hits. At this moment, please check the positions of the graphics and the machine to ensure that there is no mistake before operation.

Apart from this, the software will also monitor the machine coordinates in real time during motion. Once they are beyond the soft limits, the software will alarm and then stop all the motions.

Note: the soft limit protection depends on the machine coordinate system. If the coordinate system is not correct, the protection will also be incorrect. Thus, after the operations such as abnormal close of the system and modification of the machine parameters, users need to build the correct machine coordinate system through the operation “Go Origin”.

10.5

Frame

The laser head will dry cut a rectangle along the frame of the graphic to-be-processed by clicking the button “ ” on the console, so that you can determine the approximate size

and position for processing the sheet. The speed of walk can be set in the “Layer Parameter Setting” – “Global Parameters” – “Walk Around Parameters”.

Note: If you operate “Edge Seek” before framing, the software will record the Edge Seek results. The laser head will move along the inclined rectangle during framing. That is to say, move along the actual frame which is corrected by the “Edge Seek”. See the Chapter“Edge Seek” for thedetails.

10.6 Processing and Dry Cut

You can start processing by clicking the button “ ” on the console. During processing, the monitoring screen is displayed as below. It includes the information such as the coordinates, the speed, work time, follow height and so on.

When displaying the screen above, it cannot be switched to other pages of the toolbar, in order to prevent from modifying the graphics during processing. However, the menu “File” can stillbe used.

To modify the parameters during processing, please pause firstly, and then click the button “Layer” on the right toolbar of the interface. In CypCut V731, you can modify Layer parameters during processing, and they will apply to the next trajectory.

You can perform dry cut by clicking the button “ ” on the console. The difference between dry cut and the actual processing lies in that dry cut can select whether to follow without

laser or gas. However, all the running tracks, including the move, speed, process of acceleration and deceleration of “Pre-piercing”, are exactly same to the actual processing. You can also perform the same operations of pause, continue, forward and backward. Besides, the breakpoint memory after stopping is identical to that of the actual processing. Furthermore, you can modify the parameters after pausing, and then continue dry cut. Thus, dry cut can be used for the comprehensive inspection and simulation of the whole processing without cutting.

To open “Follow” during the dry cut, please select “ ” in“Layer Parameter

Settings” – “Global Parameters” – “Follow Parameters”. By default, it will not open “Follow” during the dry cut.

By default, it will return to the zero point automatically after completing the processing. To return to other positions after processing, please select the needed position on the console. The supported positions include zero point, start point, end point, origin point and record point. Cancelling “ ” is equal to returning to the “End Point”, that is to say, the laser head will not move after the processing. If you use the “Floating Coordinate System”, it's recommended to return to the zero point after processing. To return to record point after the

processing, please select “Recording &1” and confirm it.

Every time when the processing is finished, the process count on the console will add 1, and when it reaches the preset times, a dialog box will be popped so that you can control the production.

You can open “Auto Pause” interface to control piece management and auto pause by clicking the button “ ”. For loop work, please click the button “ ” to set corresponding parameters.

10.7 Stop, Pause and Resume

To stop the processing, please click the button “ ” on the toolbar during processing or the button “ ” on the console. After stopping, the machine will return to the zero point. If you do not hope to go back to the zero point, please cancel the selection of option “ ” on the console.

To pause the processing, please click the button “ ” on the toolbar during processing or the button “ ” on the console. After pausing, you can click the "Technic" button on the right toolbar to modify the parameters, and you can also operate the functions of the manual control part on the console, including laser pointing, switching gas, switching follow, etc.

To continue to work, please click the button “ ” on the toolbar during processing or the button “ ” on the console. Click "Non-piercing Rapid Continue" to skip piercing and continue machining.

During the pause, click the button “ ” or the button “ ” so that the machine can move backward or forward along the processing track. The distance and the speed of every motion can be set through the button " " on the console.

10.8 Breakpoint Memory

If the processing stops or suspends due to accidents, the software will memorize the breakpoint. As long as the graphics or the parameters are not modified, if you click “ ”, the software will automatically locate to the position where it stopped last time; If you click “ ”, the software will continue to process from the position where it stopped last time.

If you change the corresponding parameters after stopping, the "*" will appear behind “Start” on the console. When" "appears, functions of “ ” and “ ” can't be used.

10.9 Processing from Any Location

CypCut supports the function to start processing from any specified position. Users can rightclick the location desired, and then select “Processing from Here”. As shown below.

For safety reasons, the software will pop-up a dialog box to reconfirm after selecting “Processing from Here (F)”. After confirmation, the laser head will move to the location you specified and then start processing from there, and the tracks in front of the specified location willnot be processed.

If you want to first position it to the specified location but do not start processing, please select “Positioning Here”, so that the cutting head will move to the specified location and then go into the suspended state.

Right-click the place for many times and select “Positioning Here”, until the operation is confirmed. You can also conduct positioning in a more precise manner through “ ” and “ ”.

10.10 Global Parameters

Some movement control parameters are provided in the tab “Global Parameters” of the dialog box “Layer Parameter Adjustment”. The adjustment of these parameters will influence the smoothness of mechanical running as well as processing effect and efficiency.

Some parameters of tab “Global Parameters” are listed below.

Distance of rollback after pause

Directly follow maximum height

Automatic rollback distance on the machining path after resume

Follow control parameters

Each type of cutting head has a maximum followable height limit. When it is necessary to follow above this height due to piercing or other requirements, the Z-axis movement is divided into two steps: first, it follows to a position close to the surface of the plate, and then it lifts up. This parameter is used to set the maximum followable height.

Frog style lift

Enabling follow mode during non-cutting movements

Disable follow mode during processing

Enable positioning without following

Maximum allowable non-lifting move distance for short distances

The Z-axis is not fully lifted, and the X, Y-axis start to traverse in

order to reduce the travel time during non-cutting movements.

During non-cutting movements, the Z-axis remains stationary by default. However, users can enable follow mode for the Zaxis if desired.

Enable follow mode during regular machining, with the option to disable it if not needed.

Applicable for non-metal cutting. When selected, following is disabled, and it functions solely for positioning purposes.

If the option "no lift on short distance" is selected in the layer parameters, the height controller will not perform raising duringrapid movements when the moving distance is shorter than this value. Instead, it will remain in a follow mode.

Unit selection Choose the units of parameters based on usage habits.

11 NC Auxiliary Function

11.1 Analog Processing

After all the sorting of patterns is completed, you can simulate the processing of entire document through simulation. The simulation process allows not only the visualization of the sequence between graphics but also the visualization of the machining process within each graphic. Click " " button to start simulation, and the toolbar will automatically change to the "CNC" page. You can adjust the analog processing speed in the first column of “CNC" page, as shown below.

11.2 Edge Seek

CypCut software supports “BCS100 edge seek”, “Infrared edge seek” and “Manually edge seeking”. Click the "Edge seek" drop-down triangle button to choose the optimal method for determining the placement position of the sheet material. Seek results will be displayed in the top right of the drawing area, as shown below.

11.2.1 BCS100 Edge Seek (Enabled in Platform Configuration)

Click “ ” button under the "CNC" page or click "BCS100 edge seek" to enter the edge interface.

Width refers to length of plate in the X axis direction. Length refers to length of plate in the Y axis direction. The coordinates of the last two points in the three-point edge seek are automatically calculated based on the sheet material size. Please ensure that this parameter matches the actual size of the sheet material being detected. It is recommended to set it slightly smaller than the actual size to avoid the risk of crashing.

Plate Margin: The edge detection typically identifies points outside the sheet, which are then adjusted inside using the edge correction value. Setting a positive margin distance further offsets the points inside, while a negative value offsets them outside. This prevents jitter during cutting near the sheet edges. If you have already set a margin distance during nesting, you can set this value to 0.

6-Point Find Edge: For thin sheets, it is recommended to use 6 single-point edge detection to avoid interference caused by tooth during edge detection.

To ensure consistent starting points for each edge detection, use the "Start from preset start point" function. Use the controls on the right console to position the cutting head to the starting point and save it. Make sure the cutting head is inside the sheet when setting the starting position.

Start edge detection from the current position of the cutting head. Make sure the cutting head is inside the sheet before initiating edge detection.

If you choose "Automatic Edge Detection before Machining", the software will perform capacitive edge detection based on the graphic docking point before moving or machining begins.

Note: Before performing edge detection, please return to the reference point to correct the machine coordinate system. Also, make sure the cutting head can follow properly before initiating edge detection. The tilt angle of the steel plate should not exceed 10 degrees.

The edge detection interface is shown in the following diagram. You can perform a manual edge detection test after setting the parameters in this interface.

Click on the "Detailed Settings" in the bottom left corner to adjust the relevant default parameters. Please use caution when modifying these values, and it is recommended to use the default settings.

FindEdge speed has an impact on the edge finding accuracy, the recommended value is 100mm/s;

FindEdge height is the height that the cutting head follows during the edge finding process, and the recommended value is 4mm;

Correction is used to correct the edge-seeking result, and a positive number indicates that the laser head will be offset to the inside of the board;

Rack difference is the interval between adjacent racks.

11.2.2 Infrared Edge Seek (Enabled in Platform Configuration)

At present, “Infrared Edge Seeking” function requires matching with Omron E3Z-L61 model switch.

Before the first edge seek, the offset value of the photoelectric switch and laser center should

be determined and set in advanced parameters. Before the actual edge seek, please make sure to move the cutting head to the nearby stopping point (among upper left, lower left, upper right, lower right) as the starting position of edge seek.

“Infrared Edge Seeking” needs to set some parameters. Coarse Locate Speed is the speed of coarse positioning during edge seek, and the recommended value is 100mm/s. Precise Locate Speed is the speed of precise positioning during edge seek, which will affect the accuracy of edge seek, and the recommended value is 10mm/s without exceeding 30mm/s. The smaller the precise positioning speed is, the longer the time of edge seek is and the higher positioning accuracy is. Plate size and correction value is similar to "BCS100 edge seek".

The deviation between the photoelectric switch and the laser head can be corrected, and the rack interference can be filtered by setting advanced parameters.

You can set the following parameters: “Offset Value" is the deviation between photoelectric switch and the laser head position. After setting the "Offset Value", the software will automatically set this parameter without manually modifying. "Brace Bar Thickness" can filter out the interference of rack on Infrared Edge seeking. It is recommended to set the value consistent with the actual rack space.

"Set edge height" applies to the case of the photoelectric switch fixed in the cutting head. Users can adjust the position of the photoelectric switch thorough jogging height controller. You can read this height through "Set as the current height". When the edge seek is opened each time,height controller will move to this height. In addition, it can also move to this height by "positioning". "Fixed height edge seek" applies to the case of the photoelectric switch without being installed in the cutting head.

Note: Plate tilt angle should not exceed 40 degrees.

11.2.3 One-click Cut (Enabled in Platform Configuration)

Enabling it shows the "One-click Cut" option in the edge finding dropdown menu, used for quickly cutting off excess material along the X or Y axis.

Safe Entry Distance: When the motion exceeds the safe entry distance, the Z-axis transitions from fixed-height cutting to follow cutting.

One-click Cut in X Direction (Left-Right): After clicking this button, the X-axis first performs edge finding to the left to locate the board, then cuts into the board up to the cutting starting point. After that, it performs edge finding to the right and cuts into the board again up to the cutting starting point.

Note: When performing the cutting, use the process parameters specified for the green layer.

11.3 PLC Process

Click the " " button under the "CNC" page, you can customize the PLC process and execute them.

Note: Improper modification may lead to serious consequences! Please contact us if necessary.

11.4 Go Origin

11.4.1 Return to Origin

You can click the " " under the "CNC" page or select "All axis" under its drop-down menu to make laser head return to mechanical origin and reset the machine coordinate system.

See " Coordinate System" for details. You can also select "X only" or "Y only" under drop-down menu to make a single axis separately return to origin. If you select "Z axis first" or "Auto-focus included" when returning to origin, the corresponding actions will be performed accordingly.

11.4.2 Gantry Synchronism

During using a dual-drive gantry machine, the beam may become crooked after a period of operation due to various reasons, such as the unparallel installation of two Y axes, friction and load, which will affect machining accuracy. Gantry synchronism function can judge and automatically adjust the vertical position of the beam by recording and monitoring Z signal of Y1 and Y2 axis when go origin.

Click the drop-down triangle of "Go origin" on the "CNC" Page and select "Gantry initialization", as shown below:

Select “Execute gantry synchronism when return to origin" after completing "Gantry initialization", and enter the password. Related compensation information will be displayed in the prompt window.

Note: Make sure re-execute "Gantry initialization" after adjusting machine.

11.5 Optical Adjustment

During processing, if you need to locate the cutting head to a specific point, click " " button on the "CNC" Page and input the coordinate, as shown below.

You can also set the laser interferometer on the adjustment interface of optical path to test error between the movement position given by the software and the actual mechanical, thereby performing mechanical error compensation, also known as pitch compensation.

11.6 Diagnosis

Click the " Diagnosis " button in the File menu and select Control Card Monitoring to check the status of each part during cutting and identify any issues.

Motion axis shows each axis signal and the corresponding encoder feedback value; Pulse test is used to send fixed pulse to single axis, in order to test the accuracy of pulse equivalent. Limit

signal is used for displaying whether the cutting head hits limit. PWM is used to show the situation of laser switch. The valid situation of 8 inputs and 16 outputs are also shown.

"Encoder Detection" verifies the alignment of encoder feedback and motor rotation direction. Functions such as micro-jogging, scanning cutting, edge finding, and one-click cutting rely on consistent encoder feedback and motor rotation.

11.7 BCS100

This function must be used compatible with our height controller BCS100. By clicking "

", you can operate many actions in the software, such as Return to Origin, Follow, Absolute Positioning and One Key Calibration. And you can also operate via BCS100 monitoring interface without needing to manually interact with the physical device, which is convenient and quick.

11.8 QCW

There are two modes of laser source: CW and QCW. CW is continuous laser, and QCW is pulse

laser. By clicking " " button, you can set optical parameters.

11.9 Deviation Measurement

When click " ", the cutting head will move along the graphics to be processed. After that, a blue dotted line will appear to show the trajectory of the servo motor feedback. You can adjust process parameters required for the actual cutting according to this trajectory.

11.10 Clean Nozzle (Enabled in Platform Configuration)

Select "Cleaning Nozzle" from the left side list in the platform configuration tool and check the box . Then, the CNC module will add a "Clean Nozzle" option. Click it to access the Clean Nozzle interface.

Operating instructions:

Jog the Z-axis to a suitable position and click "Brush Top Z." During the nozzle cleaning process, you can choose whether to enable gas and select the gas parameters.

Choose a movement pattern for the nozzle cleaning: straight line, circle, or wavy line. Adjust the parameters below, and save it in the bottom left corner. Click "Start" to begin the nozzle cleaning process.

12 Appendix

12.1 Co-Edge Case

Now we demonstrate edge-shared nesting by taking the actual sample of a customer as an example. The manual drawing of the customer using CAD is as shown below.

In the drawing, unclosed graphic is shown in red. All the graphics in the drawing are straight line requiring co-edge.

It can be seen from the figure that the original drawing consists of 10 narrow parts below 6 large parts and narrow workpieces (9x2=18) at right, exactly occupying the space of a steel plate.

We now first draw 3 parts in the original drawing, and generally the 3 parts are all from the DXF drawings of customers. As shown below:

Step 1: First select all graphics of each part, and respectively implement “Group”. After grouping, the outer contours of parts will be shown in bold.

Select Part 1, and then make an array with 3 rows and 2 columns. As shown below.

Select the 6 arrayed parts, and complete co-edge for the above 6 parts by clicking “Co-edge”.

After dragging Part 2 to the position close to the top right position of the above figure, the parts will be automatically adsorbed to the boundary of Part 1 and become top aligned.

Select Part 2, make an array with 2 rows and 9 columns.

As shown below, you can select all 18 Part 2 by pulling out a pale blue box from the upper left

corner of Part 2 to the lower right corner, while Part 1 will not be selected.

You can complete the co-edge of 18 Part 2 by clicking “Co-edge”. Please note that the processing order of Part 2 must be from right to left, or steel plates will jitter or even deviate due to the lack of support.

Select co-edge Part 2, right click to select the right-to-left sorting from the pop-up menu. As shown below:

Some users may ask why the co-edge needs to be conducted after dragging Part 2 to the boundary of Part 1. They think that it is difficult to conduct selection.

In fact, the order can be exchanged. Here we first co-edge Part 3 and then drag it to the position below Part 1.

Select Part 3, make an array with 10 rows and 1 column, and then get the following figure.

After selecting 10 Part 3 and clicking “Co-edge”, they are co-edged and become a whole. As shown below. Please note that the thickness of the lines is different. Each Part 3 has a bold outline border before co-edge. The whole has a bold outline border after co-edge, and the co-edged line segments in it are all shown in thin lines.

When the mouse is suspending above Part 3, corresponding prompt will be displayed, showing that it is a combination.

Similarly, we need to conduct a sorting for Part 3 from bottom to top, so as to prevent the steel plates from jittering and deviating due to the lack of support.

When selecting the overall Part 3 after co-edge and dragging it to the lower left of Part 1, the parts will be automatically adsorbed to the boundary of Part 1 and become left aligned. As shown below:

Next, select all the graphics to co-edge Part 1, Part 2 and Part 3.

If you do not want to co-edge Part 2 and Part 3 with Part 1, this step can be omitted. Of course, Part 2 and Part 3 should be slightly dragged from the boundary of Part 1.

To prevent automatic snapping when dragging the graphics away from the shared boundary, you can temporarily disable it by pressing the spacebar. It will automatically reactivate the next

time you drag.

12.2 Operation Instructions for Gantry Synchronization

12.2.1 Platform Configuration

To enable gantry synchronization, go to the platform configuration tool .

1. Platform Configuration Tool -> Machine -> Check "Dual Drive" option.

2. Platform Configuration Tool -> Go Origin -> Enable "Z-Phase Signal"

3. Platform Configuration Tool -> Alarm -> Enter the value for "Gantry Deviation Tolerance". If the gantry beam is severely impacted or distorted, resulting in a deviation exceeding the specified value, it is important to inspect the mechanical components. Adjust the value accordingly based on the actual condition of the machine tool.

12.2.2 Gantry Initialization and Synchronization

To ensure the proper functioning of the gantry synchronization, please confirm the following before initializing the gantry:

1. The machine tool's gantry beam has been properly aligned and corrected.

2. The machine tool is capable of moving correctly and in the right direction.

3. The configuration of the home position signal is correct and valid, allowing the smooth home position process.

4. Ensure that the Z-phase signal interface of the 15-core cable is correctly soldered (Pin 5 corresponds to Z+ and Pin 13 corresponds to Z-).

5. Verify that the encoder feedback pulse count is set correctly. You can manually send pulses in the diagnostic window to observe the encoder feedback for testing purposes.

Enter the software, click on the "CNC" tab, and then select "Initialize dual-drive gantry" from the dropdown menu under "Go Origin", as shown below:

After entering the password and confirming, the machine tool will return to the home position. Then, the gantry axis will move in the positive direction to locate the two Z-phase signals. Once the action is completed, the system message window at bottom will display the position of the Z-phase signals and the Z-phase signal difference between the two axes (Y2-Y1 offset).

After completing the gantry initialization, check the option "Initialize gantry when return origin" and enter the password to confirm.

When executing the " Go Origin" or "Y-axis (Go Origin)" process with this option selected, the Z-phase signal values of the Y1 and Y2 axes will be detected. The deviation will be calculated and

compensated for. The Z-phase signal and the compensation value (Y2 compensate) will also be displayed in the system message window.

12.2.3 Precautions

1. The Z-phase signal must be enabled in order to use this function.

2. It is essential to perform a reinitialization after adjusting the machine tool mechanics.

3. The gantry synchronization may become inaccurate when the beam experiences a significant collision resulting in a visibly substantial change in verticality. In such cases, it is necessary to adjust the gantry axis mechanics and perform a reinitialization.

12.3 BCS100 Edge Seek

Starting from version CypCut 6.3.712, the BCS100 seek feature has been enhanced. It now includes advanced parameters to mitigate the impact of the rack on edge-finding accuracy, resulting in improved precision. The enhanced BCS100 seek feature requires the use of the HeightController V3.0.3299 or later versions. The older version, Height Controller V2.0, does not support this function.

12.3.1 Platform Configuration

Open the platform configuration tool, click "Edge Seek" on the left side of the interface to enter the parameter setting interface, and check "Enable BCS100 Seek".

12.3.2 Single-point Edge Finding

Leftward edge finding process without using the leapfrog function:

1. The cutting head follows the steel plate and starts leftward edge finding.

2. The cutting head moves up by a lift height.

3. The cutting head moves rightward to the boundary point.

4. The cutting head lifts up to the docking point.

5. The edge finding process ends.

12.3.3 Three-point Edge Finding

Take the docking point at the bottom right as an example:

1. Enter the size of the sheet. The values should be consistent with the actual sheet size or slightly smaller.

2. Move the cutting head to the lower right corner area inside the sheet.

3. The software will determine the edge finding positions A, B, and C based on the current position of the cutting head, sheet dimensions, and other parameters. Position A corresponds to the current location of the cutting head.

4. Perform the first edge finding in the negative Y direction and locate point X1.

5. Move to point B.

6. Perform the second edge finding in the negative Y direction and locate point X2.

7. Move to point C.

8. Perform the third edge finding in the positive X direction and locate point Y1.

9. Complete the edge finding process. Calculate the rotation angle θ and determine the bottom right vertex O of the sheet. Move to vertex O. The edge finding results will be displayed in yellow font on the top right corner of the page.

12.3.4 Edge Seeking Precautions

1. Go origin and correct the machine coordinate system before edge detection.

2. Ensure that the actual number of pulses sent by the diagnostic interface matches the feedback from the encoder. If they don't match, modify the servo-related parameters.

3. Set the values for the length and width of the steel plate to match the actual values.

4. The tilt angle of the steel plate should not exceed 10 degrees.

5. Before edge detection, the docking point for machining needs to be set to the top-left, bottom-left, top-right, or bottom-right. Otherwise, edge detection cannot be performed. The position of the docking point determines the direction of edge detection.

6. Before edge detection, move the cutting head inside the plate as the starting position for edge detection.

7. Before edge detection, ensure that the cutting head can follow the movement accurately.

12.4 Operating Instructions for Photoelectric Edge Seeking

Versions after CypCut 6.3.642.6 have perfected the function of photoelectric edge seeking. This function is available if equipped with the Omron E3Z-L61 photoelectric switch.

12.4.1 Brief Introduction

1. Effective working range: 90±30mm.

2. Mounting thread: M3.

3. Action modes: L indicates that the orange indicator light is on when the photoelectric switch has a signal output, while D indicates that the orange indicator light is off when the photoelectric switch has a signal output.

4. Sensitivity adjustment knob: Rotate this knob to change the sensitivity of the photoelectric switch.

12.4.2

Wiring and Configuration

Open the platform configuration tool, click "Edge Seek" on the left side of the interface to enter the parameter setting interface, and check "Enable Optical".

Connect the brown wire (24V+ power supply) of the photoelectric switch to any thyristor output terminal on the terminal board (corresponding to the switch power supply output terminal in the platform configuration). Connect the blue wire (24V- power supply) to the COM terminal on the terminal board. Connect the black wire to any input terminal on the terminal board (corresponding to the photoelectric signal input terminal in the platform configuration).

The "Switch Logic" in the platform configuration must be consistent with the mode

corresponding to the action switch of the photoelectric switch. It is recommended to use the L mode (indicator light on for active state).

If you have high and low working platforms, please check the option "Separate seeking heigh for pallet ".

12.4.3 Three Point Edge Seeking Process

1. For the initial use of three-point edge seeking, it is necessary to determine the deviation value between the photoelectric switch and the laser head.

2. Move the cutting head (the red light generated by the laser source, not from the photoelectric switch) to the lower right corner area inside the board to determine the initial position.

3. Select "Lower Right" from the dropdown menu under the "Three-Point Edge Seeking" option.

4. According to the initial position, the length of the steel plate, and the width of the steel

plate, two points A and B are determined, among which

a) The coordinates of point A are (X initial - 0.2*steel plate length, Y initial + 0.2*steel plate length)

b) The coordinates of point B are (X initial - 0.6*steel plate width, Y initial + 0.2*steel plate length)

5. Move to point A.

6. Perform the first edge seeking in the negative Y direction, resulting in point X1.

7. Move to point B.

8. Perform the second edge seeking in the negative Y direction, resulting in point X2.

9. Move to point A.

10. Perform the third edge seeking in the positive X direction, resulting in point Y1.

11. Complete the edge seeking process. Calculate the rotation angle θ and determine the bottom-right vertex O of the steel plate. Move to vertex O. The edge seeking results will be displayed in yellow font in the upper-right corner.

12.4.4 Precautions for Photoelectric Edge Seeking

1. Ensure that the actual number of pulses sent by the diagnostic interface matches the feedback from the encoder. If they are not consistent, modify the servo-related parameters.

2. When adjusting the sensitivity of the photoelectric switch, try to keep the green indicator light on during the board exit and entry process.

3. Set the steel plate length and width values to match the actual values.

4. The tilt angle of the steel plate should not exceed 40 degrees.

5. While the edge detection direction can be freely set in the photoelectric edge detection test interface, when using this function, the docking point must be set to one of the top-left, bottom-left, top-right, or bottom-right positions to determine the direction of edge detection.

6. Before the initial edge detection, the deviation between the photoelectric switch and the laser center should be measured.

7. Before the actual edge detection, move the cutting head (the red light of the laser, not from the photoelectric switch) inside the plate as the starting position for edge detection.

12.5 Area Output

In the platform configuration tool's left sidebar, click on "Universal Output" to set up partitioned outputs. Check "Area Output" to configure the number of rows and columns for the partitions. Drag the partition lines to adjust their positions. Each area can be assigned a universal output or no output, allowing for output variations in different areas.

12.6 Motion Parameter Adjustment

12.6.1

Introduction to Motion Control Parameters

CypCut software lets users adjust four motion control parameters: speed, acceleration, filter frequency, and corner/arc precision. Other motion settings are optimized internally. As shown below:

Items

Details

Move speed It is the maximum move speed. You can directly fill in the maximum move speed calculated by the ServoTools software.

Move acceleration It is the maximum move acceleration You can directly fill in the maximum move acceleration calculated by the ServoTools software.

Processing acceleration It is the maximum acceleration during cutting, which directly determines the acceleration and deceleration time of turning motion during cutting. It needs to be adjusted by observing the torque curve of the servo.

Low-pass filter frequency It suppresses machine tool vibrations. A smaller value enhances the vibration suppression effect but increases acceleration and deceleration time.

Arc control accuracy It represents the upper limit of arc machining accuracy. A lower value results in a more pronounced limit on arc speed.

Corner control accuracy It represents the precision of fitting corners with NURBS curves. A lower value makes the corners closer to sharp angles but results in a more significant decrease in speed.

12.6.2 Adjust Processing Acceleration

Set the speed for high-speed jog as high as possible, such as 500mm/s. Ensure that the distance traveled is sufficient for reaching the set speed during acceleration.

Use servo debugging software to monitor the torque curve during the motion. If the maximum torque is below 80%, consider increasing the machining acceleration. If it exceeds 80%, consider reducing the machining acceleration.

Adjust the acceleration until the maximum torque approaches 80%. Typically, the processing acceleration for a lead screw does not exceed 0.5G, while for gear racks, it generally does not exceed 2G.

12.6.3 Adjust Move Acceleration

You can input the maximum acceleration calculated by ServoTools software or increase the move acceleration based on the machining acceleration, such as setting it to 1.5 to 2 times the machining acceleration. The servo should not exceed 150% of its maximum torque during moving, and the mechanical structure should withstand this acceleration without significant deformation or vibration. Typically, the move acceleration for a lead screw is usually below 0.5G, while for gear

racks, it is generally below 2G.

12.6.4 Adjust Low-pass Filter Frequency

When setting the low-pass filter frequency, it is recommended to cut a sample. Start by reducing the laser power and perform marking on a steel plate to observe the accuracy of the marking path. The cutting sample should include various sizes of small circles, regular hexagons, regular dodecagons, stars, rectangles, and so on. Please refer to the image below:

To achieve high low-pass filter frequency without compromising accuracy, when cutting rectangles, polygons, and star patterns, there should be no waves at the front and back of the corners. You can refer to the provided table for recommended values or adjust within a range of two levels after determining the machining acceleration. Make sure the machining acceleration and low-pass filter frequency are matched. Avoid setting one parameter too high and the other too low.

12.6.5 Set Arc Accuracy and Corner Accuracy

It is generally not recommended to modify the parameters of arc precision and corner precision. Only make slight adjustments within the default parameter range in special cases.

To improve arc precision, decrease the arc precision parameter. This may reduce cutting speed. Smaller values result in more noticeable speed limitations. For better corner precision, decrease the corner precision parameter. This will slow down cornering, with a more noticeable effect as the parameter value decreases. Increasing the parameter value will make corners closer to a rounded shape.

To ensure proper operation, an aging test is conducted on new machines before they leave the factory. The process involves File - Diagnostic Tool -Burn-in Test.

The supported aging tests are as follows:

1. X and Y axes move at low, medium, and high speeds in the whole working area with a duration ranging from 2 to 48 hours, to test their motion stability.

2. Long-duration up and down movement of the Z-axis to test the stability of single-axis motion, along with multiple "Go Origin" tests to ensure the reliability of the upper limit switch.

3. Z-axis movement without the cutting head: Disable capacitance alarm during the move from point A to point B.

4. Z-axis movement with the cutting head: Implement a protection mechanism to prevent the cutting head from hitting the work surface during the move from point A to point B.

5. During the XY move for aging test, the Z-axis moves concurrently.
