Overview New Zealand Engineering News (NZEN) has been the industry’s journal of record since 1969. Every month it keeps its 37810 readers in New Zealand abreast of the latest news, products and processes in an increasingly automated and diverse engineering industry. With design and manufacturing driven by CAD/CAM and robotics support, we make sure our readers are kept up to the minute with technical articles and case studies from New Zealand and overseas to provide models for development. The magazine prides itself on its editorial and content independence but recognises the importance of hands-on editorial input from engineering companies and support services. Advertisers in the company’s special features sections are entitled to receive professionally written or edited articles tailored to their needs but providing added value to readers. Every month, well marked sections of the magazine and the online edition will contain valuable insights into related areas such as training and safety programmes, recycling options and the increasing use of plastics and composites to maintain product strength and lose weight. The latest from the backbone of the engineering sectors like welding and CNC machinery are not left out in a rush to new ideas. The latest techniques and products around for steel and metals fabrication, foundry operations and materials and mechanical handling are well covered. In response to trade demand, NZEN introduces, this year, a dedicated section each month on management, banking and finance, recruitment and a monthly section on clean technologies, including preventative maintenance and waste management. All this provided by a team of professional journalists in all major centres around the country.

gearboxes and CNC machined products and therefore need to be using the best available solutions,” says Mr Horsfall. Cubed3 took delivery of its new DMG five-axis machining centre in August last year after visiting the DMG/Mori Seiki stand at Austech, the Australian CNC machine tool fair in Melbourne. Managing director Stephen Horsfall and his wife and business partner Kate identified the need for a flexible and modern CNC machining centre to suit their rapidly growing business. After seeing the capabilities of the DMF180 in person an order was placed with Ben Heywood, the DMG/Mori Seiki area sales manager. Increased demand has lead to recent investment in top class machine tools and CAM software. “We researched the market thoroughly and are delighted with the combination of our DMG five-axis machine and Delcam’s PowerMILL CAM software,” says Mr Horsfall. Ease of programming and reliable toolpaths were key requirements for Cubed3 in selecting a CAM solution.

Mike Bishara – Managing Editor NZ Engineering News

It is the job of the whole team at Engineering News to make sure we

The 2012 version of Delcam’s PowerMILL CAM system for high-speed and five-axis machining includes a number of new strategies, together with more general enhancements to make programming faster and machining more efficient with the best-possible surface finish. The most important new option is flowline machining. With flowline machining, the toolpath is divided between a pair of drive curves in a constant number of passes, rather than having a varying number of passes with a constant

stepover. The toolpath will have its start and end passes on the drive curves, with the intermediate passes blending between them. This approach gives smoother results since it ensures that each pass travels over the full length of the area, rather than leaving the part or making major changes in direction during the pass. It produces a better surface finish on the part and minimises wear on the cutter and the machine tool. Flowline machining can be applied across

The flexibility of the DMF180 was a key factor in Cubed3 machine selection as it would be required to perform a diverse range of functions from product development through to lights out machining. Ease of programming and reliable toolpaths were instrumental in the choice of a CAM solution with Delcam’s PowerMILL “We needed the CAM software to be intuitive, easy to learn and reliable. We are very happy with PowerMILL,” he says. The flexibility of the DMF180 was a key factor in machine selection as it would be required to perform a diverse range of functions from product development through to “lights out machining”. With a travel of X 1800mm, Y 700mm and Z 700mm, Mr Horsfall could immediately see the benefits of the large

stationery table measuring 2100mm x 700mm with the integrated round C axis table in the centre for his changeable and demanding workload. “During the day I can machine large gearbox housings from huge billets and then run lights out at night with multiple small parts mounted vertically on a tombstone fixture on the integrated C axis table as you would on a horizontal machining centre”, he says.

part of a surface, across a complete single surface or across multiple surfaces. In addition, intermediate curves can be added between the boundaries of the area to give even greater control over the toolpaths. These might be needed for particularly complex fillets or when machining gently-curved surfaces to a smooth finish. Another important new option in PowerMILL 2012 is the ability to control the angular point distribution during five-axis machining. This option can be used to keep the machine tool moving smoothly when there is rapid angular change in one of the rotary axes of the machine tool. The problem occurs mainly when moving around sharp corners but is also important when the

machine is operating near a vertical tool axis. If the machine tool is near the gimbal lock position, small movements in the toolaxis vector can result in large movements in one of the axes. In both examples, smoother tool-axis changes can be achieved by increasing the density of the points in these areas. The user can specify the maximum angle that the tool axis can move between points. Extra points are inserted automatically to ensure the specified maximum angle is not exceeded.

“I looked at other machines but none could come close to the DMF 180’s large useable machining envelope combined with a +/- 100 degree swiveling B axis head. “Even with the swiveling B axis head at 90 degrees I still have full useable Z and Y axis travel of 700mm – long tool overhangs and deep hole drilling are no problem”. The DMF180 excels in both heavy and high accuracy machining due to an extremely stable foundation made of polymer concrete. The huge machine base is a mineral casting made of polymer concrete which is

extremely dense, thermally stable and will not twist or bend. Polymer concrete absorbs vibration up to 10 times better than cast iron and is less influenced by fluctuation in workshop temperatures. “The proven effects are a reduction of natural frequencies, quick abating of frequencies, reduction on noise emissions and an improvement in the work piece surface finish and increased cutting tool life of up to 30 percent”, Mr Heywood says. “It’s also ecologically friendly as the mineral casting process uses 30 percent less primary energy when compared with

cast iron – and the polymer concrete is recyclable”. The travelling column achieves 40m per minute in the X, Y and Z axis on large 45mm guide ways. A closed loop measuring system with glass scales maintains 0.01mm positional accuracy anywhere in the machining envelope. Short “chip to chip” times are achieved by fixing the tool magazine to the travelling column so there is no waiting for the machine to return to a home position to perform tool changes. The oil/air lubricated spindle exceeds Mr Horsfall’s requirements for both heavy roughing with 19kW of power and 100Nm of torque, and high-speed machining in aluminum with 14,000RPM. This DMF180 is also equipped with through-spindle coolant and easily switched to external air via M code – a stand-alone coolant tank handles the 600 litres of coolant and keeps it in good condition with 50 micron paper filtration. To further assist Cubed3 with quick set up and maintained accuracy in a production environment the machine was equipped with touch probe, laser tool setting, 3D Quick set and a 3D model for integration into the CAD system. The Blum laser will measure tool length and diameter in seconds to micron accuracy saving huge amounts of time in set up. “We also utilise the laser for tool breakage and wear detection when machining critical parts,” Mr Horsfall says.

“Parameters for tool wear/breakage are easily set by the operator and new tools can be selected from the magazine or machine stopped if they fall outside my preset tolerances preventing scrap components being machined”. To further maintain accuracy, five-axis DMG machines are supplied with hardware and software for checking and calibrating the kinematics of the machine. “The machine kinematics can be checked and automatically adjusted by the operator running a simple measuring cycle using the 3D Quick Set which takes less than a couple of minutes to complete,” says Mr Heywood. In the past this was a time consuming job for a skilled engineer – DMG have eliminated the need for an engineer to call and the downtime which would be required”. As many of Cubed3’s clients are at the cutting edge of their respective industries such as aerospace and international marine, the company looked to partner with a machine-tool supplier which reflected these same values of quality design and technology. “We support Cubed3 to achieve its goals and the company supports us in return – an order for CTX510 eco-CNC lathe has since been placed and will be exhibited at EMEX in May before delivery to Cubed3”. “Another DMF180 will be on display at EMEX this year, so please visit EMEX in May and see this machine in action,” says Mr Heywood.

Compac Sorting Equipment took out the top honour at the New Zealand Hi-Tech Awards in May. Judges described the company as “the Rolls Royce of its industry”, citing its “laser-focused priority on market-driven R&D” as a key reason for its global success. “A world class innovator, delivering 21st century technology that makes its agricultural customers, including those in New Zealand, more competitive.” In 2001 Compac completed the first commercial installation of its market-leading InVision 9000 blemish grading system for a citrus customer in California. And in 2003 the company installed one of the largest sorting lines in the world – a

40 lane by 60 metre long pre-grade line with the InVision 9000 blemish system and a 12-lane by 70 metre packing line – for Sun Pacific in California. This 40 lane line for mandarins and oranges is capable of sorting 400 fruit per

second amounting to around 1.4 million fruit per hour. The latest offshore success for the company is a US$15 million order from the US. “Bigger than a football field, this is a 40 lane, 100 metre long turnkey sorting

system that will handle 20 million mandarins a day,” says R&D manager, director and 16 year veteran of the company, Nigel Beach. “The longest design we have done in the past is 80 metres.”

Modular Conveyor Ltd designs and manufactures a full range of conveyors. Its band driven roller (BDR) conveyors are an optimum solution for the conveying of flat-bottomed products, such as those found in warehousing and distribution, food packaging and parcel handling.


CL’s BDR conveyors are most efficient at speeds of 7 to 60 m/min (23 to 200 ft/ min) under relatively clean, dry, oil-free environments. These conveyors use a rotating drive shaft that runs through the length of the conveyor, which in turn transfers drive to each roller through low friction spools and polyurethane drive bands. The drive method provides a number of significant advantages to BDR conveyors over other types of powered roller conveyors, including economy and efficiency as they are able to drive long lengths of conveyor per motor and to also continue the drive around bends. BDR conveyors are flexible. The rotating drive shaft can be used to power a number of secondary devices such as spurs, 90-degree transfers and wheel diverts. The roller’s rotation can be easily and individu-

ally changed. Modular design allows for easy reconfiguration or additions to meet future needs. The simple drive system makes for a clean operation as it eliminates “pressure rollers� and flat belt surfaces that accumulate dirt and grime in other roller conveyors. A BDR conveyor is quieter than other powered roller conveyors due to its low number of moving parts and the fact that the drive bands exert constant tension on each roller. This eliminates a major source of rattling inherent in other roller conveyor designs. BDR conveyors are safe to use. While there is more than enough drive to move products, each spool driving individual rollers is able to act as a slip clutch. This allows any roller to stall with low pressure if a foreign object becomes caught between rollers or a jam occurs. A full length guard covers the rotating drive shaft on the under-side of

the conveyor. MDL offers a number of standard conveyor modules and secondary devices that enable a system to be configured to provide a solution for most conveying requirements, including: • Straight and bend modules • Spur and merge modules • 90-degree chain or poly-cord transfer devices • Wheel diverts • Product blade stops • Product “drop-stopsâ€? • Carton turn devices • Inline scale units Components used in MCL BDR conveyors are designed for long life and require minimal maintenance. The rollers incorporate sealed precision bearings within moulded anti-static techno-polymer housings. This means that while ensuring quiet running rollers, the conveyors can achieve longer life and higher possible speeds than those from other manufacturers who use non-precision bearings in

pressed steel housings. Conveyor frames and stands can be supplied in a number of finishes, such as powdercoated EG steel, 2-pot epoxy coated EG steel, zinc-plated or stainless steel. Rollers are available in galvanized, stainless steel or PVC tube, and a soft PVC sleeve

can be fitted for the handling of delicate products, or for increased grip in incline or decline situations. BDR conveyors are designed and built to complement other MCL conveyor styles, so for systems that may require gravity or belt conveyors to be integrated into the layout, clients

can be confident the system will not only be fit for purpose but will retain a “family look� for aesthetics.

hree skilled and enthusiastic young mechanical engineers travel to London this month as part of a 17-strong team of ‘Tool Blacks’ to compete at the 41st WorldSkills International competition. In the August issue we ran an article on WorldSkills competitor William Taylor of Etech Industries, Palmerston North. He was joined by Brad Wood of South Waikato Precision Engineering, Tokoroa, and Mat Pascoe of Lyttelton Port Company, Christchurch. Each represented New Zealand as the best of our best young tradesmen in their respective fields. To get to the competition William Taylor won the Sheet Metal Technology skill category at the National WorldSkills competition in Christchurch late last year to qualify to compete in this trade skill category at the international event in London. His fellow countrymen – Brad Wood and Mat Pascoe took out the welding and polymechanics (fitting and machining) skill categories respectively at the national event to qualify. All three were then selected by WorldSkills NZ chief executive, Peter Spencer, to represent our country as role models for the future of our engineering trade skills. “The NZ WorldSkills competition was definitely challenging,� says Mat. “They

were a bit of a head scratcher and I had to work really hard.� Mat spent time perfecting his polymechanic skills before heading to London with the support of his WorldSkills NZ mentor and Waikato Institute of Technology, Roland Spirig. He also completed two block courses as part of his preparations for the event at the WINTEC campus. “Working with Roland has been great,� says Mat. “He really knows his stuff.� Polymechanics involves repairing and maintaining machines and systems in production plants. Mat will exercise a diverse range of skills, including manufacturing, fitting, milling, drilling and more while working on his competition project. “There’s a diverse range of aspects that Mat needed to be trained in,� says Roland. “It’s a tall order.� With Roland living in Waikato and Mat in Christchurch, meeting was difficult for the pair. However the two also corresponded regularly via email to discuss training strategies and progress. “We worked through previous WorldSkills competition projects to make sure we covered all the skill sets that Mat might need to call on,� says Roland. Brad Wood also followed a strict training schedule in

preparation for the event, with a tremendous amount of support from his assigned WorldSkills NZ mentor, Jason Beals of the NZ Defence Force, and South Waikato Precision Engineering’s production welding manager, John Harris, along with sponsorship support from Weldwell NZ. “It’s been hard, I’ve been doing 25-30 hours of training a week, on top of my normal 40 hour work week,� says Brad. “I’ve been practicing at work and at local businesses – everyone’s been really supportive.� Pressure, says John, was a key focus for Brad’s latter stages of training before departing. “Brad has a natural aptitude for welding – we really needed to challenge him so he can take whatever the judges might throw his way in London.� “Brad definitely put in the hard yards,� adds his mentor, Jason. “He is in a good position to do well – his skills should peak at the right time; some competitors have been training for over two years so they might plateau�. Finally, William Taylor will be pleased he’s now got his chance to see where his skills ‘stack up’ against other qualified young sheet metal fabricators, from all four corners of the globe. Etech Industries’ managing director, Trevor Douglas, says William showed real promise and dedication in learning his

craft right from the start; qualities he continued to display in his work and his WorldSkills preparations. “He has the right attitude to go far in this industry – the quality of his work is really high, and he’s a team player who always puts in extra hours to help us meet some crazy deadlines,� says Trevor. While William was keen to see where his skills placed him on an international scale he isn’t over-awed by the competition, recognising the personal and professional development opportunity it represents. “I never imagined something like this was even possible for me, it’s a really exciting opportunity,� says William. William’s mentor, Competenz industry manager Steve Brooks,

has the added distinction of being a deputy chief judge for the Sheet Metal Technology skill category of the WorldSkills International competition. “His welding and some other skills were already quite strong,� says Steve, “so we focused on his strengthening his CAD skills before he leaves for London. “His haka is getting better too – we encourage the team to share a bit of our culture while they’re away. WorldSkills offers a really rich experience for William, and all our young competitors.� The WorldSkills International event is held every two years, bringing together over 1,000 of the world’s most talented young tradespeople from 50 countries to compete across 46

different trade skill categories. All competitors must be under the age of 23 at the time of the competition. Competitors complete a complex project over an intense four-day competition format, testing their planning, technical knowledge, and skills in a high pressure environment. We wish all three of our engineering Tool Blacks – who each completed their Competenz and ATNZ apprentices within the last 12 months – all the very best for the competition.

The reduced water content of K-Screed provides added strength and durability, eliminating the cracking, curling and debonding that often occurs with standard sand and cement screeds. The superior impact resistance also protects thinner section floor finishes, such as vinyl, for far longer. Drying times for K-Screed are only seven days per 25mm thickness (depending on ambient temperature), whereas standard screeds can take 25 days per 25mm thickness. K-Screed also offers superior compressive strength of +30N/ mm2 as compared to 15-20N/ mm2 achieved by standard screeds. In addition, K-Screed can take foot traffic just 24 hours after being laid. K-Screed is suitable for use with a diverse range of final floor finishes including vinyl, carpet, marble, ceramics and various resin flooring finishes.

Polymer Group, in conjunction with contractors Dean Taylor and Tane Jarrett of 2CK Design and Development Ltd, supplied the Rhino Armafloor decorative quartz floor topping, chosen not only for its attractive non-skid finish, but also because there was an urgency associated with the project having to be installed over one day, commencing on a Saturday evening. The decorative quartz finish was specifically blended by Polymer Group to replicate a sandy ocean floor look, complementing the rock walls and other features created by Dean, which used the Polymer Group foam imitation rock wall products.

ow the third busiest international passenger airport in the world, Hong Kong’s new airport was built between 1992 and 1998 to an innovative design conceived by leading international architects Foster & Partners. In the largest screed contract ever awarded at the time, a total of 250,000 square metres of Isocrete K-Screed was applied. Every day since, the system has stood up to continual high levels of foot and trolley-wheeled traffic in the main passenger terminal building, retail, food and entertainment areas, as well as associated maintenance areas and plant rooms. The Airport Authority has commented that the flooring has certainly stood the test of time and the decision to opt for the high-strength screed back then has paid off with the original floor coverings still looking good today. “Hong kong airport is an excellent example of the longterm durability and integral strength of K-Screed. Because K-Screed forms such a strong and durable sub-surface, final floor finishes last much, much longer. This significantly minimises the need for costly

Despite everything you ever heard about how rare titanium is, in fact it is one of the most common elements on earth. Titanium (Ti) exists naturally in an oxide form predominantly with other elements, as in our iron sands, says the Titanium Industry Development Association (TiDA) chief executive Warwick Downing. “After the iron is removed the remainder is around 40 percent Ti. Extracting Ti is achievable and is done around the world, the majority ending as the white base in paint and in sunblock,� he says. “The difficult part for the metal is extracting the oxygen. It is the oxygen-free metal that we know as having the biocompatibility, high corrosion resistance, and best strength-to-weight ratio of any metal. “It is the extraction of the Ti that creates the cost of the final metal.� The good thing about using Ti powder is that there is almost no waste and it is non corrosive and non toxic. “Couple this with highly efficient manufacturing methods and the ability to use Ti alloys increases,� he says.

TiDA was formed in 2010 to help New Zealand companies add value and develop new products for the international market, while remaining competitive against cheap labour economies. A key part of that brief was to introduce titanium powder technology to New Zealand industry and help companies build up and improve consolidation capability. While receiving strong support from New Zealand Trade and Enterprise, “we encourage customers to come in and see how it is done and what can be done. “New Zealand manufacturers can compete with China on price because our labour component costs, while more expensive, are spent on design and not labour intensive manufacturing,� Mr Downing says. Powder metallurgy is a highly efficient process because labour costs have little impact – the design and materials used are of greater importance. Doctors in the UK have 3D printed a complete jaw which has been produced with composite powders including titanium. “Small numbers or large numbers make

no difference. We can machine sinter 60 differently designed parts at the same time as long as they fit in the 220mm x 220mm build area,� says Mr Downing. The pride and joy at TiDA is a $1.5 million laser sintering unit which it shares with Triodent Ltd in Katikati. “In using the laser sinterer we can take a CAD model and build it up layer by layer, melting the powder only where it is needed. “We prefer a bit of time first time, but we have a fair idea what will work and what will not. Basically in free form manufacturing there are very few boundaries – it is a little more difficult to manufacture parallel to the plate, for example, where we may use a snap-off leg to lift it off the plate. “In CAD design terms, 3D printing titanium and laser sintering can be cheaper than machining using stainless steel – it is lightweight and does not have to be solid,� says Mr Downing. Metal injection moulding can be used for larger volumes and profiles similar to aluminium can be extruded using Ti alloy powder, giving properties similar or

Kiwi growers on the trail of food and beverage fraudsters

Oritain chief executive Helen Darling says natural products absorb the characteristics of the soil, water and vegetation that nourishes them and those characteristics provide the fingerprint

By Les Watkins

Dr Peter Falloon has had enough of cheaters trading on his 20 years of cultivating the best asparagus seeds

Identity theft in the food and beverage industry is more widespread than previously believed. The latest to be found out is Simon Mickleson who used fake labels to transform ordinary wines into vintages supposedly worth $1.3 million. The hunt for a solution often leads to the door of Oritain chief executive Helen Darling. Asparagus specialist Dr Peter Falloon typifies a growing band of Kiwis fighting fraudsters who, in addition to robbing food producers of billions of dollars annually worldwide, are helping to sabotage the excellent international reputation of New Zealand. Dr Falloon is the managing director of Aspara Pacific, this country’s only asparagus seed breeder. He has spent 20 years developing cultivars highly-regarded around the world. But success has made him and other leading New Zealand producers vulnerable to counterfeiters, eager to exploit their reputation, who the OECD estimates are making illegal profits of more than US$250 billion a year and growing. “We export our seed to many countries including the US, Japan and South Africa.

For years, even in the US, there have been a lot of questionable dealings with vegetable seeds,” says Dr Falloon whose base is at Lincoln, near Christchurch. “Inferior F2 seed, which generally gives a yield of 20 to 30 percent less than our F1, is either deliberately wrongly labelled or mixed with top-quality seed. “Growers can’t tell the difference. They tend to look at the price, go for what seems the best buy, and eventually of course, they are disappointed. That has the potential to do us tremendous harm so we decided to be pro-active – and took steps to protect ourselves.” That led him to pioneering foodverification company Oritain Holdings of Dunedin which scientifically identifies the ‘fingerprints’ of products – including those of meat, milk, fruit and vegetables,

which are created by their source of origin. Oritain chief executive Dr Helen Darling explains: “All animals and plants absorb the natural properties of their environment. The adage about being what you eat is true of most natural products. Each absorbs the characteristics of the soil, water and vegetation that nourishes them and those characteristics provide our ‘fingerprint’. “The isotopic composition of rainfall varies from area to area because of environmental differences and factors such as distance from the coast. So distinct differences can be identified between the rain in Central Otago, for instance, and that in Waikato. The soils also have variations in their trace elements which again enable us to establish a product’s origin.

“The counterfeiters use all sorts of tricks – copying genuine labels, re-packaging consignments and so on – but what they cannot do is accurately copy that fingerprint. That can’t be tampered with because it is right there in the product. “So if counterfeiting is suspected, as has often been the case with products from this country, we can prove whether or not they are the genuine article. “This is becoming increasingly important because brand New Zealand is worth a lot – being regarded as superior in terms of production, safety and quality. “Top brands – watches, handbags, apples or whatever – are always targets for counterfeiters and, particularly in times of economic hardship, counterfeiting is a growth industry.” Falloon discovered that truth in February.
