On a ‘finer’ note

G

rinding is coming of age and how! From the conventional to super abrasive, and from automotive to aerospace, it has evolved significantly to meet the ever-growing complex needs of user industries. Also, in the race to achieve better finish quality, grinding plays the role of a high value-add differentiator. Ultra high precision machines and special grinding equipment come handy in attaining the much sought-after superior accuracy. At the same time, it is imperative to explore more economical ways in order to improve grinding productivity, part quality and production cost. Going forward, the specific type of manufacturing practices will primarily determine the prospects of grinding wheels. Cases in point are the wheels made of new forms of synthetic abrasives such as seeded gel aluminium oxide and Cubic Boron Nitride (CBN). As the demand for grinding lighter yet stronger concept grows, the use of advanced materials such as polycrystalline super abrasive materials or CBN and aluminium oxide holds the potential to make the grinding wheel a viable option for shaping hard materials. From the viewpoint of India, with a rise in outsourcing of high-end engineering jobs, especially involving advanced materials such as Inox, aluminium alloys, temperature resistant materials, to name a few, there should be a positive ripple-effect on high-end grinding Editor Manas R Bastia Senior Features Writer Hema D Yadav

applications. For more such latest advancements related to grinding, turn to ‘Sector Watch’. Now, let us look at another area that is experiencing some of the mega trends as well. The material handling segment has evolved from wooden planks in cluttered shop-floors to the latest breed of swift forklifts and electric stackers, and from bulky control panels to stateof-the-art & sleek ones. In fact, with the advent of compact designs & small turning radius, multidirectional forklifts and other material handling equipment facilitate better space utilisation. Another significant trend sweeping this sector is the demand for more environment-friendly equipment with less fuel consumption and reduced emissions. However, the material handling segment still depends on import to a sizeable extent and is challenged by high import duties on sourcing of spare parts for the imported equipment. Till this sector attains critical mass in the country and the domestic production base expands significantly, it may remain a concern area. The ‘Industry Update’ offers a detailed perspective. Take a look.

ore industries in India are witnessing significant growth compared to that in the last few years. Various innovative and effective techniques are being implemented by manufacturers to cut cost and stay competitive, while ensuring quality and excellent finish of products at the same time. It is here where grinding industry plays an important role. Grinding, which is a finishing operation on components involving high precision, has become a key area of interest for the metalworking industry because of its high value-addition to achieve quality finished goods. Ultra high precision machines and special grinding equipment are required for attaining accuracy. Coupled with state-of-the-art techniques, availability of skilled manpower and capability to deliver effectively, the manufacturers in Asia now hold the key to grab potential tooling business from around the world.

Propelling growth Today, customers have become more demanding. They expect high precision products at low cost, which has forced manufacturers to constantly improve the performance of machines. Adopting the most advanced technology for grinding is essential for staying competitive in the market. The economic growth of China and India has induced demand for grinding machine manufacturers. Talking about India’s position in global market, Rajesh Khanna, Chief Executive Officer, WENDT (India) Ltd, says, “There are many companies in India that have a good standing in the global market and we also have a big role to play in the global market because of the size, competent labour, good technology, and raw material availability in India.” As China has the fastest growing steel industries globally and India is moving towards becoming the second-largest steel producer in next five years, these

factors indicate a positive sign for roll grinding and cut-off machines in the Asian market in near future. According to Mathew Jacob K, Chief Technical Officer, Pferd India, “Functionally and aesthetically, grinding plays a crucial role in manufacturing, and particularly in today’s world, where things revolve around lighter yet stronger concept, good grinding is even more significant.” India has many steel projects and capacity expansion projects, which provide a great opportunity for grinder manufacturers to grow in the field of metalworking. Grinding machine manufacturers are looking at exploring the huge market potential at this point. Witnessing the boom in the manufacturing sector, grinding machine manufacturing is the right place to be in. Talking about the current demand for grinding, Santosh Prabhu, MD, Tool Grinding Technologies, says, “Indian market for grinding is mainly driven by automotive industry followed by engineering, defence, etc. Auto industry is high volume-based and price sensitive, whereas engineering and defence are special applicationbased. Indian industry still imports grinding machines for high-end applications. Majority of crankshaft, cam shaft, fuel injectors, nozzles in common rail, etc, are the applications where Indian industry depends on imported machines.” Consequently,

India is emerging as one of the best global investment options and as long as industrial investments continue to be made, the demand for capital goods such as industrial grinders will grow.

Role of grinding wheel

Manufacturing industries have a growing interest in finding economical ways to improve grinding productivity, part quality and production cost. Grinding wheels are the most common and important types of grinding elements used in this industry, so having a good understanding of the type of grinding wheel and its proper application becomes important. Grinding wheels come in many different sizes, shapes and abrasives. Their function is to remove material from the workpiece to smoothen, sharpen or polish it. This happens by the abrasive action of the wheel. Each grain of the wheel acts as a cutting tool. The abrasive grains are the actual cutting tools of a grinding wheel. Each cutting grain is sharp and irregular, and they chip off tiny thin flakes of the material while cutting. Abrasive type, abrasive grit size, hardness grade, grain structure and bond type affect wheel performance. By varying the other parameters like work speed, traverse, feed, etc, an operator can make a wheel act one grade softer or harder. According to V S Goindi, Chairman, Goindi Group, “Grinding, as Key factors in selecting the right grinding wheel applicable to the metal cutting industry, is generally a finishing  Material to be ground and its hardness operation on components  Amount of stock removal and finish required especially in industries like  Grinding machine power automotive, aerospace, white  Wheel speed goods, etc, which calls for high  Area of grinding contact precision.

and so on. The prospects of grinding wheels depend upon the type of manufacturing practices that will be adopted in the future. Wheels made of new forms of synthetic abrasives such as the seeded gel aluminium oxide and CBN are also being used. Further, the use of advanced materials such as ceramics and composites will increase demands for new types of grinding wheels. Research and development in making cutting tools out of polycrystalline super abrasive materials or CBN and aluminium oxide will make the

They also find applications in the aerospace industry for turbine blades, root & tip profiles,

grinding wheel a viable option for shaping hard materials.

Simulation in grinding Grinding is one of the most important machining methods for finishing, which is performed by using a large number of abrasive grains with irregular shapes and random distribution. While this feature enables accurate and high quality machining, it makes it difficult to analyse the grinding process. In order to solve this problem, several computer simulations have been developed, which help users to statistically calculate geometric interference between a grain and a workpiece. It gives user flexibility to visualise the result as an animated image using a three-dimensional graphics technique. Prabhu says, “New generation CNC control system uses software and 3D simulation to work out the programs offline, which increases the productivity. Acoustic sensors reduce the idle time while dressing and approaching for the part, thereby increasing productivity. Most of the grinding process works on closed loop measurement system and this helps in high rate of consistent production.” The simulation makes it easy to understand the microscopic grinding phenomena, and makes it possible to analyse the surface generation process quantitatively. It can be used as a practical tool for predicting the grinding results such as surface roughness, and for optimising grinding parameters such as infeed rate. The key advantage to tool grinding simulation software is that users can design and perfect a complete tool grinding process off-line and prior to actual production. Khanna says, “There are new products coming up in the market, which use exotic materials. There are super alloys, hard-to-grind materials, composite materials and these materials can only be dealt with grinding. So there is a growing demand in this segment.”

The manufacturing industry across the world is influenced by globalisation, changing economic environment and ever-changing lifestyle choices. Customers worldwide have more choices than ever before, putting pressure on grinding system manufacturers to deliver quality products as efficiently as possible. This has induced manufacturers to do away with old production systems and adopt new methods of production. The automation used in industries have increased the productivity and reduced human error and time. The new technological developments have reduced the need for human presence, therefore increasing accuracy and efficiency to meet the ever-growing demand from customers. “New product designs are focussed on high precision in high material removal rate. Rigidity of the machine and thermal stability are the design features, which

increase the consistency of grinding quality and wheel life,” says Prabhu. The Indian manufacturing industry is successfully competing in the global marketplace and registering high growth every year, but large sections of the sector still suffers from the technology gap and poor infrastructure. Goindi observes, “Regarding the requirement of Indian industries, it is becoming more dependent on the local suppliers as against imports, as was the case earlier. However, there is still a gap in technology levels in many areas of critical applications when compared to countries like Switzerland, Germany Japan, etc.” He further adds, “There is a great need for higher R&D investments in this vital segment of machine tools as has been done by China. This is particularly important, keeping in view the strategic needs of defence and aerospace industries. It is important that a national policy for

development in this sector is formed soon – with partial financial help from the government.”

Promising business The image of India as a manufacturing hub has created huge opportunities for Indian industry. Since grinding is a widely used method of precision machining, India seems to be the preferred destination for grinding machine and equipment manufacturers. Driven by domestic demand and the cost efficiency advantage of India, the business outlook for industry in the country is expected to grow considerably. Mathew avers, “We expect the grinding for high-end applications to grow at a higher rate, since the awareness level for safer and specialised performance tools are catching up fast in the industry.” The rise of automobile, heavy engineering and cement industry in the country has positively affected the grinding machine segment and this is expected to continue in coming years. “More advanced, aggressive yet stable grinding grits will become the future when it comes to demanding grinding applications. As more high-end engineering jobs are being outsourced to India, especially involving advanced materials like Inox, aluminium alloys, temperature resistant materials, etc, we expect significant increase in high-end grinding applications,” notes Mathew. The challenge for grinding industry is to meet the international standards and yet stay competitive. This can be achieved by more investments in R&D, absorption of technology, research activities with academia, etc. Over a period of time, as the market becomes more mature with increasing volumes, co-operation between industries will increase, which will help grinding equipment manufacturers understand the industry requirements and provide customised solutions, promising a robust future for grinding.

The main requirements from the tool include lifetime, the surface quality of the roll and the grinding time. As many roll grinding machines are fully automatic, great importance is attached to consistent quality, ie, the reproducibility of the grinding tools.

Initial situation: Quality assurance All raw materials used at Tyrolit are subject to strict and exact quality standards, which naturally undergo inspection at the stage of ‘incoming goods’. Resin-bonded grinding tools are subject to grade variations, which influence the stock removal rate and wheel lifetime (G-ratio). Certain specifications are manufactured with

a variation. The reasons for these deviations are quality variations in the raw materials and the production process of the grinding wheels. In most cases, the technical specification is defined together with the individual suppliers and matched to our needs. In the past years, the tolerances for the individual quality characteristics have been narrowed down as far as it is meaningful and able to be executed according to the present state-of-the-art. This means that those variations of our products on account of raw materials have been reduced dramatically. To be able to examine the stability of the product quality more closely, the production process has to be more exactly analysed.

New grinding solutions by Tyrolit making way for change in the industry

58

MODERN MACHINE TOOLS - June 2011

At considerable expense, an examination was made of the extent to which the raw materials or production processes influenced the variations. At the same time, the critical production steps for the product quality control were defined. Manufacturers of resin-bonded grinding tools have to accurately inspect every individual production step, in order to guarantee maximum reproduction. However, positive findings are also to be gained from the achieved result:  The exact definition and inspection of the production sequence constitutes know-how & decisively influences the product quality  A quantification of the variations makes the specification finding easier  In future, bonds will be developed, which react even more robustly against raw material variations, production variations and environmental influences

Solution The already mentioned knowledge has served as the basis for the development work in the area of roll grinding wheels. Two projects were carried out in 2004 namely ‘Technical application support with roll grinding’; and ‘New systems – conventional resin’. The former was started in order to establish the reproduction of the mechanical strength. Figure 1 shows the reproducibility of two specifications by repeated production lots. The mechanical strength serves as inspection dimension for the quantification, which correlates well with the G-ratio. In order to be able to carry out the follow-up tests, it is helpful to know the mechanical strength of the samples. The new inspection method will not only be used with sample wheels but carried out accompanying production so that product quality is guaranteed.

MATERIAL HANDLING EQUIPMENT

NextGen mechanisation With the manufacturing sector charting an uninterrupted growth path and every industry fast donning a more modernised avatar, it is possibly the best time for the material handling equipment sector to explore new avenues. A couple of decades back, this industry had started with the most basic equipment, but now it is all set to experiment and go beyond the conventional.

Indian manufacturers are also looking at having swanky shop-floors, with the latest material handling equipment adorning their facilities.

Back on track After witnessing a major setback from the global recession, the material handling systems industry has come


Industry Update back on track. Most experts in the industry feel that after the dip in production, the industry is up for a significant growth in the near future. “The first quarter of 2008 was good, but from the second quarter up till early 2010, the industry was in a recession mode. Material handling equipment come under capital goods, and most capital goods purchases were in a suspension mode in most industries. The business started recovering slowly in 2010 and registered a growth of 20 per cent. The growth of the industry is certainly poised in the right direction,” says an elated S A Mohan, CEO, Maini Material Movement.

Changing milestones Manufacturers spanning various sectors, including aerospace and automotive, are looking to implement automation solutions at their shop-floor. While dock lifters and scissor lifts are fast replacing wooden planks and scores of labour force, the material handling equipment presently coming into the market is complete with high level of automation. There is a huge shift in the technological aspect as well. From the initial equipment categories with huge bulky control panels, it has now evolved to become more sophisticated and sleek. According to industry experts, at present over 80 per cent of the manufacturers are in the unorganised sector. And this is where the industry envisages a change. Various material handling equipment manufacturers have come up with some of the latest technologies in the Indian market. An array of electric and semi-electric stackers throng the market with compact designs & small turning radius, which facilitates the use of material handling equipment with the least possible space requirement. The Indian market also offers a gamut of lift tables with the capacity to hold weight of up to 5,000 kg and more. Multi-directional forklifts are now entering the market,

It is a matter of education so that people start adopting such material handling equipment, and we feel that in the next three to five years, things will significantly change. In India, the trend has been more inclined towards adapting to new technologies. And as that happens, the material handling system industry will also have its share of growth.

S A Mohan, CEO, Maini Material Movement which allows companies to utilise space better and not worry about turning radius. “The cost of real estate is going up, which makes optimal use of space a necessity. Moreover, the trends are changing in every area, for instance the construction of warehouses. Earlier, warehouses were around 6 metre high. Today, warehouses over 16 metre high are built. This calls for appropriate material handling equipment, which can store and retrieve materials kept so high. The aisle space is also reduced so that more number of racks can be placed in the available space. We have come up with equipment, which has small turning radius, so that it can move around the narrow aisle space with ease,” notes Mohan. According to D S Sekhar, Managing Director, SFS Equipments Pvt Ltd, productivity can be enhanced by selecting the right equipment and there are many innovations in the market today.

Trendsetters Even as most industries are moving towards modernisation, material handling equipment is finding its way across all sectors. The Indian market is also trying to be in sync with the global market. While tow tractors are catching up with the

trend in the automotive industry, the same are also widely becoming popular in airports, railways and various other places. Apart from the regular industries, material handling equipment is also paving towards new sectors like wind energy parks, paper manufacturing, among others. Also, as the shop-floors of most industries are dramatically seeing a change, the material handling machinery manufacturers are working with the customers to provide customised solutions as per the shop-floor requirements. There is an upcoming trend in the area of equipment used for loading and unloading of heavy materials from ships wherein such activity can be done accurately in minimum possible time, without causing much damage. With the advancements in machines, operator comfort is also being given high importance, and innovations such as joysticks in forklifts replacing steering wheels are some of the latest product offerings. “The material handling equipment industry is growing because materials are getting heavier. For example, coils are much bigger than it used to be earlier. For customers, it is important to rationalise material handling during the manufacturing process. They want equipment, which would

As the material handling equipment industry is still in a nascent stage, the initial challenge faced by the industry is to create a demand for the high-end products available in the market. Even as quite a number of organisations are revamping their shop-floors to accommodate the latest material handling equipment, this sector has a long way to go. “It is a matter of education so that people start adopting such equipment, and we feel that in the next three to five years, things will significantly change. In India, the trend has been more inclined towards adapting to new technologies. And as

that happens, the material handling system industry will also have its share of growth,” believes Mohan. Besides the fact that most industries still depend on the unorganised sector, thereby posing a problem for material handling equipment industry, this sector also faces the challenge of sourcing spare parts for imported equipment at lower cost due to high import duties. But things are changing fast, and companies in India are working towards improving efficiency & productivity rather than being labourintensive in their operations. In the logistics industry, where speed and efficiency are the key, it is imperative to have material handling equipment. While such equipment is seen as a cost-adding activity, it is essential that there is an emphasis on speed when it comes to delivery of products in the market. “From a manufacturing and logistics operation scenario, material handling equipment is becoming unavoidable these days, irrespective of the cost of labour and it is seen as a value-addition rather than a pure cost. The material handling equipment industry is set to boom in the Indian market in the coming five years, with a projection of 20,000 new equipment requirements annually from the current figure of 4,000,” points out Sekhar.

While the material handling system industry is still trying to tap the domestic market, a global reach is a long way to go. “In the Western world, the market is organised, so the size of the industry is also huge, whereas, in case of China, the economics is different. There is huge amount of local consumption and export as well. So the combined demand is high. In India, we are mostly manufacturing it for the domestic consumption, and therefore the demand is still low and the industry size per se, in terms of volumes, is small. For example, in India, we manufacture 5,000 forklifts a year; whereas in Western countries, it is around 200,000-300,000. In China, the figure comes to over 200,000,” states Mohan. But the industry is optimistic about the growth in this sector. “India is a growing market and it is a good option to do business in this region. The steel and automobile industries are witnessing growth. I think it is important to deliver high quality products. We cannot deliver ‘off-the-peg’ products to this market, but devices specially designed for individual fields of operation. In almost all cases, we collaborate with our customers in order to elaborate the best possible solution for the task required,” feels Moraru.

Green solutions Making green movement a part of the industry is a constant effort. There has been a significant demand for making material handling equipment more eco-friendly. There is a preference for electric-driven instruments, which would save fuel, reduce emissions and produce less noise. The industry is conducting indepth research to come up with new technology and pave way for more environmentfriendly equipment in the future. “The industry needs to make more efforts towards going green with the use of battery operated equipment,” concludes Sekhar.

Market Insights

INDIAN CRANE INDUSTRY

Scaling new heights Having started as simple machines used to carry up and bring down materials, cranes and hoists have come a long way. These have become more sophisticated with time, and simplified various processes in manufacturing. Material handling equipment have greatly reduced human efforts and also brought down the process timing, thereby increasing the output. Tushar Mehendale

ith India pulling out all the stops in building world-class infrastructure, crane manufacturers are looking at exploiting the emerging market potential this presents. Witnessing the boom in the manufacturing sector, crane manufacturing offers huge opportunities. Thus, this segment is treding on the growth trajectory.

The Indian market The Indian crane industry is split along the lines of organised sector and unorganised sector. Further, it is divided geographically. Hence, there are only a handful of players

in the organised sector who are really active on a pan-India basis. There are around 200 crane manufacturers in India and the industry is all set to grow at 30 per cent annually. The industrial cranes market in India is highly fragmented. The organised sector accounts for almost 30 per cent of the total marketshare, while small crane companies (almost 150) constitute the rest. Interestingly, almost 30 per cent of the crane manufacturers fall under the governmentowned companies and the remaining 70 per cent under the private sector. The latter is the most vibrant part of the Indian economy, which is growing at a high pace and willing to adopt new technologies.

June 2011 - MODERN MACHINE TOOLS

Market Insights Western India contributes 50-55 per cent of the total requirement; southern India follows with 20-25 per cent; northern India with 15-20 per cent; and eastern India with 5-10 per cent.

Growth drivers The industrial crane sector has a strong positive correlation with basic economic indicators. Any fluctuations in the economic indicators reflect immediately on the sector. Keeping in mind the current movements, India has a few key factors in its favour that will ensure the continuing growth of this segment. The resumption of a steady inflow of investments from foreign multinationals, increase in domestic spending on infrastructure construction & power projects, robust domestic growth rates, strong internal fundamentals and a healthy banking system make India an attractive destination for companies that are facing shrinking sales in other economies. Consequently, India is emerging as one of the best global investment options. And as long as industrial investments continue, the demand for capital goods such as industrial cranes will grow. The key driver of the industrial cranes industry currently is the infrastructure industry, closely followed by steel and automobile industries. The Indian infrastructure is under–developed and there is huge potential for improvement. Within the infrastructure industry, construction and power projects are the main drivers. In the next fiscal, the demand for construction equipment will rise as a result of several projects in the areas of road construction, irrigation and power, among others. Demand for industrial cranes would be high, led by ongoing massive investments in industrial and SEZ projects. It would also get a boost from greenfield and brownfield expansion of refinery projects. While the Indian market provides a plethora of opportunities to crane manufacturers, the challenges in this sector cannot be overlooked. Manufacturers face bottlenecks while

68

MODERN MACHINE TOOLS - June 2011

undertaking business development in terms of making the users understand the application and utility of the machinery. Skilled manpower development is yet another issue, which needs to be addressed appropriately to allow optimum utilisation of the equipment.

Customer-focussed approach The Indian industrial cranes industry is getting more customer-oriented, as the Indian customers are ever-evolving. From being exposed to low quality equipment a decade back, today they have an array of high quality equipment. Hence, the demands of the customers are also growing. Initially, the customer used to have a single line focus, ie only on the pricing aspect, without bothering a lot about the technical comparisons among different offerings. However, now the customer goes through the complete technical specifications and ensures that the end-product encompasses all the functional features as well as other aspects like reliability, safety, ease of maintenance, etc. Another remarkable trend in this sector is that with several international tie-ups happening, the industry has started to have considerable global influence in terms of quality and use of better technology. As far as availability of high-end solution goes, the Indian materials handling equipment sector is at par with the global industry when it comes to industrial cranes. Today, the latest and best technology is available in India and Indian industrialists are embracing these products with open arms. Cost-efficiency is definitely important, but the competitive advantage of cranes lies in technological superiority. India is following the international trend of consolidation in the industry; most Indian manufacturers are associating

Potential for foreign investors For international firms looking to enter the Indian market, the time is right with investments soaring in each of the construction segments. Foreign investors can enter the domestic market by setting up marketing companies. This allows them to establish a brand and also, at a later stage, to establish their own manufacturing units. Players with technological know-how can succeed, as technology is the major entry barrier. A foreign investor or manufacturer can have a joint venture with an Indian partner through technology transfer. Any product with better installed technology has greater demand compared to its competition. Potential customers have to be made aware of technological advancements. A foreign investor can also associate with an Indian manufacturer whose processes are good by providing monetary support to establish more manufacturing units.

Future scope India has a vast technical talent base, an established component vendor base and low labour rates, all of which lend it the distinct advantage of becoming an export hub for the Middle East and South-east Asian markets in the area of material handling equipment. India can also be regarded as a future R&D hub for international giants because of low R&D manpower costs. Manufacturers should provide customised solutions by providing additional accessories and specifications geared towards maximising the customers’ productivity. To sum it up, India is an exciting market, and is expected to offer huge opportunities in the material handling equipment segment over the next 20 years.

MODERN MACHINE TOOLS - June 2011

India is witnessing a growth phase, with several global players in various sectors including steel coming to India. Grinding is a crucial part of almost every industry, be it aerospace or automobile. Unlike earlier times, high-speed wire rod steel mills have become order of the day. It in turn calls for using precision grinding tools to improve production. Similarly, other industries have been experiencing intense competition to produce components that are lighter, more exacting, while being harder and tougher. Industries now prefer harder and exotic alloy materials, which are tough-to-grind, necessitating the usage of high performance grinding tools. This is where the grinding industry plays an important role. Moreover, the developed nations are looking at developing countries like India to serve as their manufacturing hub. As a result of which the precision components are getting shifted to Brazil, Russia, India and China. In India, we have seen a healthy growth in excess of three times the country’s Gross Domestic Product (GDP) in the grinding industry.

Q Tell us about the market in India as you

envisage it five years down the line. As mentioned above, we have seen a healthy growth in the grinding industry last year. For instance, we have grown by


Leaders Speak 46 per cent over the last year with the Super Abrasive business growing by 32 per cent and Non-super Abrasive by 138 per cent. We are optimistic of this positive trend continuing over the next five years.

Q Though India is gaining

momentum in the field of technology and research, sophisticated machinery are still being imported. What is the reason behind this and the role of WENDT in changing this trend? There is a big dearth of high-end precision grinding machines in the country, which are traditionally being imported. The Indian psyche is against paying higher price for machines. Customers rather tend to choose low-priced machines than going for a quality precision machine due to price factor. Now with many MNCs coming into India with their pressing demand on quality and precision, the Indian manufacturers have no choice. The

customers are now ready to invest in the precision machines to address their demand and are also willing to pay for the differential. This is where we are trying to bridge the gap. At WENDT, we are now manufacturing high-precision CNC surface grinders, cylindrical grinders, precision profile grinders that would address this growing need. We are using state-of-the-art German technology weaving the price requirement of the Indian industries and offering machines in line with their expectations.

Q What advantages does the

Indian market provide to the customers vis-Ă -vis global competitors? India still has the labour advantage, which is available at lower cost. China too is considered to have an edge when it comes to cheap labour, but I believe the workforce there is now becoming expensive. In India, however, we have committed, hard working populace coupled with relatively cheaper man-

hours and a workforce having good knowledge of English, which is globally accepted. The other competitive edge we have is the high level of IT literacy and computer programming skills. All these put together makes India an upcoming hub for CNC machines. This makes us more versatile and competitive in the global market.

Q What is the demand pattern in

the market? As the industry is going for more toughto-grind materials for components, the demand for super abrasive grinding tools is continuously on its uptrend, and with various global companies looking at the Indian market, the growth in demand is likely to continue. We do not really have a demand-supply gap as we work on the philosophy of building capability, while also ensuring adequate capacity to address spurts in demand. We are capable of producing and supplying as per the customer requirements in terms of both quality and quantity.

Leaders Speak We do not really have a demand-supply gap as we work on the philosophy of building our capability, while also ensuring adequate capacity to address spurts in demand. We are capable of producing and supplying as per the customer requirements in terms of quality and quantity. Q Which latest advancements

the industry would see in the near future? Grinding industry has come a long way. From the conventional abrasive grinding with abrasives like aluminium oxide and silicon carbide, users have graduated to harder super abrasives like diamond and cubic boron nitride in resin, metal, vitrified and electroplated bonded system. The latest trend is towards special bonding system like permanent bonded system or the brazed products where abrasives are chemically bonded to make them more aggressive and long lasting. With super abrasive being expensive, the industry is now looking at faster processes like laser-assisted machining, high performance fine grinding water jet cutting & wire sawing, etc.

government comes up with a clear policy for development of these industries and make them more organised & globally competent, it would give a boost to the grinding industry as well.

Q How does India fare in the

global market? There are a few companies including our parent company M/s Carborundum Universal Ltd in India that have a good standing in the global arena. With CUMI and WENDT GmbH as joint venture partners for technology, WENDT (India) has a big role to play in the global grinding market. The Indian products are technologically competitive and fare very well in the global market in terms of priceperformance ratio.

Q Tell us about your innovative Q What are the major challenges

that the industry faces currently and what is being done to overcome these? The major challenge is that unlike other industries, here one has to be a local regional player. One cannot have a centralised plant at a particular place and conduct business across the world. One needs to be nearer to the customer since it is a service-oriented and technology-driven industry. This is not all. There are several unorganised players in the market who are small time players and may adopt short-term practices for their sustenance, which poses continued nuisance for the organised sector. Further, there is a good market for diamond tools in industries such as stone, gems polishing and diamond jewellery & lapidary, which is mostly dominated by the owner-driven companies. If the

products. Last year, we have formally launched a practice called ‘Innovation@Wendt’ to develop innovative products for the industry taking into consideration the present and latent needs of customer. This year, we plan to introduce two new innovative products to address the price-sensitive segment. Focus is on having sizeable percentage of innovative products, thereby adding to our product basket. We are also into making special purpose machines, tailor-made to customer requirement by incorporating innovative features.

Q What are the technological

advancements in the area of diamond grinding that would take the diamond industry to the next level? Irrespective of the fact that there are small unorganised players, we strive hard

to make products, which can still provide a competitive edge to our customers. The diamond processing industry is big in India. A majority of diamonds are being processed in India, China and other developing countries. In India, this industry is using imported products and low-cost tools sourced from countries like China. We are trying to provide these products with the technological edge, which can help the industry in processing the diamonds faster and cheaper, thus at an affordable price.

Q Today, most of the businesses

are incorporating green policies as part of their business plan. What initiatives have been taken by WENDT to be environment-friendly? All activities and practices at WENDT are focussed towards being environment-friendly. We have a unique effluent treatment plant with zero discharge. We have used the natural topographical gradient so that the pumping of water and consumption of power is bare minimum. We also monitor issues, which might possibly cause harm to the ozone layer and have banned the use of items & chemicals like carbon tetra chloride, tri-chloro ethylene, etc, in our plant altogether. Also, while taking up any new process or project, we first check on any impact that it might have on the ecology.

Q Expansion plans of your

company‌ After a modest start with a small unit way back in 1983, we have added facilities over the years. From being a small insignificant player , today we are the most preferred supplier of super abrasive tooling to the industry. A few years back, we started our subsidiary WGTL in Thailand and subsequently added WENDT Middle East in Sharjah. In order to strengthen the regional presence in South East Asia, we are prospecting to set up a subsidiary in Indonesia and service centres in India.

Sidhartha Dhand Director

With all four facilities in Ghaziabad and Bengaluru spanning a total area of 1,50,000 sq ft, and 400 trained workforce, over 200 machines are rolled out every year under the banner. The Bengaluru unit alone has a capacity of manufacturing 120 machines per annum and is on its way towards expansion in the near future.

Manufacturing milestones Over the years, the company has been consistently adding some of the most innovative products to its product catalogue. Right from stroke and length match grinding machines with which it started off, it has added new technologies, keeping pace with time and customer demand. With machines such as heavy duty cylindrical grinding machine, piston ring profile grinding machine, CNC heavy duty cylindrical grinder and compact CNC grinder model, the company has made a mark in its own way. Some of the most recent products rolled out by the company in the market include the Rhino – the 7-axes CNC crank pin grinder, iGrind 50 CNC internal

grinder, eGrind 200 hydraulic cylindrical grinder for tool room applications, universal grinder B-axis machine, crankshaft main journals grinder and heavy duty cylindrical grinding. Catering to smaller industries and making technology more affordable for them, MGT has come up with a simple Grind 50 CNC cylindrical grinder. The latest addition to the company’s product line is Stallion SH 63 STAT CNC grinder equipped with hydrostatic guide ways. MGT also specialises in a unique process called scraping. To add value to its available technology, it has employed human resources who have received special training in the up scraping and down scraping process from Switzerland. “Every year at MGT, we push our boundaries, innovate and come up with something new. We have successfully created a technology that allows us to completely automate the grinding of ceramic components in our grinding machines,” avers Sidhartha Dhand, Director, Micromatic Grinding Technologies Ltd.

Recently, MGT added its first European branch in Grenchen, Switzerland. With this office, the company aims to make an impact in the European market and head towards its mission to become a global player. Among its numerous other undertakings, a joint venture with JTEKT Corporation, Japan, is a feather in the cap for the company. The collaboration took place in 2008 under the name Toyoda Micromatic Machinery India Ltd, and since then, with their expertise in CAM grinding technology, they have jointly come up with four new machines, including a new cost-effective small cam lobe grinding machine, which adds greater value to the existing product line. The company exports to Europe, Middle East, Australia, the US and South East Asia, besides providing services to almost all major automotive companies in India. MGT exports three to four per cent of its production every year to the global market. “Grinding is all about super finish and accuracy. It is a surface finishing operation. We give great importance to transparency in pricing and machine building activities. This is the way we try and add value to our services,” says Narayan Muramatti, CEO, Micromatic Grinding Technologies Ltd.

Innovation and research Unique products are the result of in-depth research and knowledge of customer need. MGT is heavily engaged in Research and Development (R&D) programmes to bring out new and competitive products for the market. The R&D centre at the company is recognised by the Government of India, and it is constantly engaged in developing new technologies to improve existing machines and create new ones. In 2010, the centre witnessed a breakthrough in its R&D. For easy setup change and reducing setup change time, the company has come

The technology is easy to understand and operate, making it easy for beginners to readily create and edit programs and run the production. Last year, the company set up its Information Technology (IT) infrastructure to be able to meet all business needs, even before they arise. The company has 23 servers, with VMware (Virtualisation) as the driver of its IT technologies. The deployment will be completed this year, making the infrastructure at MGT more reliable and future-ready than before. “Precision is the quality of exactness. And at MGT, we try to understand, create and deliver precision that is more economical,” avers Dhand.

Employee-friendly campus Great care is taken to ensure employee satisfaction at MGT. While numerous activities are conducted at the facility to keep the employees’ spirits high, care is taken about their safety. Most machines used in the unit come with full enclosure and mist collectors to keep a check on possible health hazards to operators of the machines. Apart from safety, the company offers equal opportunity to its employees to express their views and

ideas across all grades of workers, thus making them feel that they are an important part of the entire process. “We have not just built a skilled labour force in our company, but also integrate collaborative thinking across all levels sans hierarchy, and this helps us to innovate better. So, for most of the new products, we have ideas coming in from every quarter of the company,” ascertains Dhand. Recently, the company was featured as one of the three Indian companies in the book series Humanism in Business by a Switzerland based international organisation ‘Humanistic Network’. This book is a collection of business case studies from all corners of the globe. What unites this group of businesses is that all of them are highly successful market actors in a competitive environment and yet they consider their ultimate aim as the generation of societal benefit rather than maximum profit. “At MGT, we encourage every individual to communicate freely and openly, as this is an effective way of showing respect to individuals. In addition, it avoids all difficulties related to inevitable loss of communication down the line, which often results in distorting the facts and unfortunate interpretations at all levels,” affirms Dhand.

The company also gives high consideration to being environment friendly.

As part of its eco-friendly efforts, the company uses re-usable pallets for transportation from its Ghaziabad to the Bengaluru factory, thus saving on a large number of trees on an annual basis. The company has also deployed a Vapour Absorption Machine (VAM) since 1997 at the Ghaziabad unit, for Chlorofluorocarbon (CFC) free air conditioning. Here, powder coating technology is being used in place of spray painting to reduce air pollution. “Every company exists in the context of its ecosystem and while most of the effort is directed towards business goals, it is important that the ecosystem of the company is protected and enhanced over the years. The negative impact of mindless resource utilisation, with no efforts at environmental enhancement, has given rise to huge global problems. We, on our part, always seek to enhance the environment in a multitude of ways,” reflects Dhand.

Future plans With this high rate of growth in the industry, MGT has achieved a turnaround of ` 56 crore. The company further aims to reach its target of ` 100 crore this year. “We are in the process of adding more machines and manpower to our facility in order to increase productivity. We are currently producing 120 machines per year and have a target to roll out over 300 machines at the Bengaluru unit, with the expansion in place. And while we are trying to understand the need of our customers, we are simultaneously strengthening our vendor base, as most of our business happens through the vendors,” concludes Muramatti.

INDIAN OFFSET POLICIES

Smoothening the runway for future growth Ranked as the second largest aviation industry in the world, India is flying high with a robust economic growth. The burgeoning Indian middle class coupled with an increasing number of air travellers will further strengthen the country’s aviation industry. Also, the rising need to enhance/modify existing fleet and include new ones has resulted in increasing opportunities and potential for national as well as international companies. Hema Yadav

T

he growing Indian defence quota has initiated a fierce competition among the defence suppliers from US, Russia and Europe. The country’s soaring aerospace industry has created opportunities for manufacturers and Global Service Providers (GSP) in India. The rising demand from the defence and civil aviation sector combined with the State’s procurement offset policy has resulted in participation and

alliances. The offset policy drafted by the State, which is related to defence procurements has been extended to buy state-owned carriers also such as Air India.

Background of India’s defence offset policy The growth of the country’s defence industry has been sporadic since independence. It did not follow any definite plan though emphasis was laid on enhancing indigenous defence

Offset was made mandatory in defence contracts of the size and nature as prescribed in the 2005 policy Overseas companies were allowed the flexibility of forming joint ventures with the ones in India A new organisation called the Defence Offset Facilitation Agency (DOFA) was established comprising representatives of all stakeholders - the Services, Defence Public Sector Undertaking (DPSU), Defence and Research Organisation (DRDO), etc

production capability. An attempt to change this was made during the 1962 India-China war. However, this did not derive the desired result due to several factors such as: The Soviet friendship: A major factor in the incapability of India designing a strong military industry was the easy access to defence equipment from the former Soviet Union. Sophisticated defence equipment were transferred to India under the rupee-rouble arrangement and a few license production facilities were also established in India, for example for the MiG-21 aircraft. The prevalent Cold War ensured continuous supply of military equipment to India, alienating it from Western superpowers like the US. However, with the collapse of the Soviet Union, India lost easy access to sophisticated defence equipment at cheap prices. The issue was compounded by the absence of an alternative source of modern defence equipment. The situation became worse with the almost complete disruption in the supply of services and spare parts necessary to maintain the predominantly Sovietequipped Indian armed forces. The navy was particularly affected, as it was dependent on Soviet designs and equipment for some of the ships that were under construction in India. This led to incurring huge expenses and time overruns in the construction programme of naval vessels. This compelled India to seek alternative channels to develop a certain level of indigenous capability. Closed economy: Prior to the liberalisation policy of 1990s, India

86

MODERN MACHINE TOOLS - June 2011

obtained technical knowledge for the repairs and local production of a few critical spare parts. These efforts were mostly case-specific and were not components of any systematic strategy for the comprehensive development of a defence industry. They were also service-driven in the absence of any coherent strategy to achieve selfreliance. However, the liberalisation of the Indian economy that almost coincided with the collapse of Soviet Union harnessed India’s productive capabilities, providing impetus to the goal of developing a domestic military industrial complex.

Defence procurement procedure The year 2005 witnessed the formulation of the country’s first ever defence offset policy to assist in developing the country’s defence industry. The policies were incorporated in the Defence Procurement Procedure (DPP) 2005. The initial policy introduced a 30 per cent offset in contracts valued above ` 3 billion under ‘buy’ and ‘buy and make’ categories. Under the policy, foreign vendors had the liberty to discharge their obligations either through the execution of defence exports of Indian items and services or through investments in India’s defence infrastructure. They also had the option of selecting Indian firms in consultation with an industry associate of their choice to implement their offset obligations. These offsets were non-mandatory, leaving the Services Capital Acquisition Plan Categorisation Committee (SACPCC) to recommend the incorporation

of offset obligation in acquisition proposals. On the flip side, the policies lacked clarity and were not assigned to any designated agency in the Ministry of Defence (MoD) for guiding, overseeing, executing and monitoring the implementation. The prevailing confusion resulted in failure of the policies, which did not yield any dividend or benefit. Building on the disaster of DPP 2005 the Government of India made significant changes in DPP 2006.

Indian aviation industry India is carving a niche for itself as a manufacturing hub due to its technical expertise and cost-efficient environment. The manufacturing segment is projected to be another main beneficiary of the State’s offset policy, and is likely to result in deals cut across the 30 per cent offset limit. A report published by market research firm RNCOS, titled ‘Global Aerospace Market Forecast (2006-2009)’ described Indian aerospace industry witnessing three main trends – fast growth in civil aviation, development in manufacturing (especially in the private sector) and emergence of India as an aerospace technologysourcing centre. Global aerospace players have a preference for services of GSPs from India like Infosys, HCL, Wipro and TCS, where their Global Delivery System (GDS) have been valued on international scale, making it easier for them to meet the current offset requirement of 30 per cent.

DPP 2011 From January this year, a new DPP is in place. However, the more liberal offset policy compared to its predecessors will not be applicable to the country’s largest defence procurement, the Medium MultiRole Combat Aircraft (MMRCA), thus quashing the hopes of many vendors. Programme offsets require foreign vendors to provide work for Indian

Preference will be given to indigenous design, development and manufacture of defence equipment. Therefore, wherever the required arms, ammunition and equipment are possible to be made by the Indian industry within the timelines required

by the Services, procurement will be made from indigenous sources. Whenever the Indian industry is not in a position to make and deliver the equipment as per the Service Quality Regimes (SQRs) in the requisite time frame, procurement from foreign sources would be resorted to, in accordance with the DPP. While examining procurement cases, the time taken in the procurement and delivery from foreign sources vis-Ă vis the time required for making it in the country, along with the urgency and criticality of the requirement will be examined as per the DPP before deciding to proceed with procurements from foreign sources. Based on the approved Long Term Integrated Perspective Plan (LTIPP), equipment/weapon systems/platforms required 10 years and further down the line will by and large be developed/ integrated/made within the country. Sub-systems/equipment/components that are not economically viable or practical to be made within the country may be imported, ensuring their availability at all times. However, as far as possible, the design and integration of the platform/system will be undertaken within the country. The government will endeavour to build up a robust indigenous defence industrial base by proactively encouraging larger involvement of the Indian private sector in design, development and manufacture of defence equipment. Towards this end, efforts would be made in progressively identifying and addressing any issue which impacts; or has the potential of impacting the competitiveness of the Indian defence industry in comparison to foreign companies. To synergise and enhance the national competence in producing state-of-the-art defence equipment/ weapon systems/platforms within the price lines and timelines that are globally competitive, all viable approaches such as formation of consortia, joint ventures and public private partnerships etc within the

government approved framework will be undertaken. The Academia, Research and Development Institutions as well as technical and scientific organisations of repute will be involved for achieving this objective. The government will further simplify the procedures under the ‘MAKE’ category of the DPP in such a manner that it enables the indigenous design and development of the required equipment/weapon systems/ platforms by both public and private industry in a faster timeframe. Service Headquarters (SHQs), while laying down the qualitative requirements for defence equipment/ weapon systems/platforms to be developed/integrated/made, will exercise due diligence at all times to keep in view feasibility and practicability of the QRs. It will be ensured that the systems/platforms designed/developed/integrated in the country provide a competitive edge to our services vis-à-vis our potential adversaries. The government also recognises that development of complex systems is generally a stage process with incremental changes progressing from Mk-I and Mk-II and so on. The stage process will be

90

MODERN MACHINE TOOLS - June 2011

followed. However, at every review of such developmental projects by the Defence Production Board or Defence R&D Board as the case may be, it will be ensured that our equipment, weapons systems and platforms are such that they provide an edge to our forces over our potential adversaries. In case of delays in the realisation of the projects, the corresponding proposal will be processed as per the DPP and the option of ‘Buy’ shall be followed for the necessary numbers till indigenous production capability is established where after indigenous systems shall be procured. Policies will be put in place to encourage the OFB, DPSUs and the private sector to strengthen their research and development wings so that constant upgradation and improvement in systems under manufacture is possible. The government will set up a separate fund to provide necessary resources to public/private sector including Small and Medium Enterprises (SMEs) as well as academic and scientific institutions to support research and development of defence equipment/systems enhancing cutting edge technology.

In all cases of transfer of technology, DDP along with DRDO, HQIDS and SHQs will be involved in identification and evaluation of requisite technology, and subsequently would be responsible to ensure that appropriate absorption of technology takes place in the Indian industry. Thereafter, successive generations of the weapon systems/platforms will be developed in the country. Upgrades will be carried out by the Indian industry as far as possible. DRDO, HQIDS, SHQs, OFB, DPSUs and the private sector will work in close co-ordination for continuous upgradation in systems. The committees set up under the DPP will process the acquisition proposals in accordance with the above policy guidelines. Through the current DPP, the Ministry of Defence is encouraging participation of the Indian industry and supporting them to become self-reliant. The crucial question is how effectively the government will work with the private sector to develop indigenous platforms and systems, given the limitations of time and technology that may be available in the country. The DPP 2011 is aimed at speedy indigenisation and to substantially reduce dependence on foreign suppliers. Under the current policy international companies winning defence contracts in India will no longer be required to invest in direct defence equipment to fulfill offset obligations. However, the government has allowed itself the right to bypass the bidding process if ‘strategic considerations’ dictate. The new DPP for 2011 has broadened the scope of the offset policy to include civil aerospace, internal security and training within the ambit of eligible products for the discharge of offset obligations. The changes brought in by the current DPP will provide a wide range of offset opportunities to defence vendors and encourage building up of indigenous manufacturing capability in crucial areas.

Essential parts and equipment for aerospace machining Aerospace machining is a highprofile industry in machining and manufacturing of precision components/parts, which are critical and high precision in nature, with close geometrical tolerances from bar stocks, billets, forgings and castings required for building aircraft, helicopters, rockets, missiles, spacecrafts, launch vehicles, satellites, etc that operate in space or outer space. It involves extensive deployment of CNC machinery such as CNC machining centres, CNC milling and CNC turning centres supported by grinding, jigboring, honing, broaching and other conventional machines. Non-traditional machining processes can be carried out on CNC wire EDM, chemical milling and waterjet & laser-cutting machines. There has been a major shift in the usage of conventional to CNC machine tools, with simultaneous multi-axes machining capabilities for machining complex & 3D contouring parts, as they have close geometrical dimensional tolerances and stringent quality checks. These adapt high-speed machining technologies, high-end graphics, Computer Aided Design and Manufacturing (CAD/CAM) software/ workstations for generating shop floor drawings, process sheets, 3D solid

and surface modelling of complex contoured components. These are suitable for Numeric Control (NC) tool path simulation & verification, generating NC codes, specially coated cutting tools for hard & dry machining, special cutting fluids for maximising productivity, advancements in workholding systems, for high-precision metrology instruments/ equipment such as 3D CNC Coordinate Measuring Machines (CMM). Further, these latest technologies call for high investments.

Business outlook The government’s new defence procurement & offset policy regime is undergoing a paradigm shift and is being credited to open business opportunities to the tune of $ 100 billion in the next few years. The Indian aerospace component manufacturers would be the main beneficiaries of this. Also, with Hindustan Aeronautics Ltd (HAL) and Indian Space Research Organisation (ISRO) stepping up their roles in global aerospace businesses and being aggressive in exports business, offset trade policy initiated by the government and Maintenance Repair Overhaul (MRO) facilities in India, growth is likely to be on a rapid pace.

Several companies are working towards AS9100C Quality Management System Certification established by International Aerospace Quality Group (IAQG), as it is now mandatory for exports.

Future of the Indian aerospace industry Aerospace machining market is growing at a reasonable rate and the projections for the next 10-15 years looks positive, which is a good news for the Indian machine tool building industry that was earlier focussing on general engineering, automotive, tool, die, mould, capital goods, consumer durables and intermediate goods

industry has responded positively to this requirement and found it viable to make additional investments to carry out R&D for this sector. Earlier, we were not permitted to import high-precision multi-axes and multi-tasking machine tools due to various sanctions and restrictions. We are glad that now the machine tool industry in the country is technically advanced and is competing with global machine tool suppliers. This leads to a healthy competition and the money stays within the country itself. To capture the aerospace market, the machine tool industry has to carry out more R&D activities, attract additional investments, recruit technical & highly skilled manpower dedicated to this segment, constantly interact with the aerospace machining industry, give additional & adequate training to their workforce, generate innovative ideas within the organisation, bring in awareness among the workforce about the aerospace requirements & quality issues and sustain market competition.

Green design without compromise Companies can gain a sustainable competitive advantage and be environmental stewards – through robust design and optimisation. Thierry Marchal

I

f most companies have considered environmental regulations as a major obstacle to successful business, the leading organisations are now seeing the opportunities and competitive advantages standing behind this apparent constraint. This trend has been recently quantified by a BCG / MIT Sloan survey published in January 2011. Environment-friendly designs are expected to consume less energy and to be less demanding for raw materials. Those could quickly translate into cost reduction, either

operating cost or manufacturing cost, as well as a product price increase to value the green flavour of the product. But this will not succeed if the integrity of the environment-friendly solution is not demonstrated. Designing a sustainable product cost-effectively and quickly does not compromise with product robustness and performance looks like an impossible challenge with traditional technology. Best-in-class companies changed these threats into major opportunities by switching design to the virtual world. Using engineering simulation, they are virtually designing, manufacturing and testing new solutions much faster and more thoroughly than ever before. A much larger number of prototypes are investigated opening the door to green design without compromise with cost, robustness, performance and safety.

Manufacturing Excellence from anywhere, and using a cell phone are routine activities, even in emerging countries. However, the world cannot sustain such exponential growth forever. The planet has received a wake-up call about addressing overconsumption. Many scientists state emphatically that we are putting our planet, and the human species, in danger. The population is rapidly draining the world’s fossil energy sources; at the same time, emissions from these fuels are negatively impacting the environment and its natural evolution. Huge amounts of waste material are being stored with the hope that the Earth can cope with it. Most people are aware that the globe cannot sustain these practices forever. While a growing number of people are urging the world’s population to do something about it, many individuals are unwilling to sacrifice their comfortable lifestyle.

Without a doubt, cars could be more environment-friendly, but if you surveyed the planet, would you find people willing to pay more to achieve this objective? Most would

be reluctant to accept significant reductions in performance, speed or acceleration. Green building is a common aspiration, but will the occupants tolerate being a bit less warm in winter, and a bit more warm in summer? Renewable energy is a ‘must do’ only if the resulting power is less expensive and at least as stable. An admirable goal: Can we reach it without personal compromise? Common sense dictates that we cannot meet such expectations using traditional approaches and technologies. Real breakthroughs may be necessary to achieve sustainability goals in these areas:  Better energy management: Fossil fuels remain an important energy source, but they could be used more effectively and selectively. Sources of renewable energies should be exploited. Transportation, construction and manufacturing must become more energy efficient.  Pollution reduction: Twenty-first century lifestyles result in the release of huge quantities of various materials into the environment, making absorption and recycling of these substances

difficult without a direct impact on the planet. Product lifecycle: After a lifetime of use, products quickly become waste material. Shortened product life increases the amount of waste. processing recycled materials into new products in a cost-effective manner can benefit greatly from modern simulation technology.

Virtual experimentation, virtual testing, virtual prototyping If sustainable products and processes today are merely ‘nice to have’, it is likely green design will become mandatory in the future, legislated and forced by market pressures to develop better solutions. Pioneers and leading companies are already preparing for this evolution by designing sustainable solutions, but the challenge is daunting. Environmental friendly products may require major innovations that could impact both cost and robustness. Innovation usually requires intense experimentation and optimisation. Real breakthrough solutions need systematic testing to ensure that new designs behave properly throughout the entire lifecycle. Experimentation and testing processes are typically time intensive, costly and difficult to manage in a highly competitive world. Best-in-class companies are addressing this issue by switching to the virtual world. Numerous reports and industry studies, suggest that an order of magnitude more experimentation can be done virtually for a smaller cost. Engineering teams can vary numerous parameters to identify the best combination of sustainable design, minimal cost and maximal performance. Leading companies are systematically testing their virtual product prototypes against conditions that would be experienced throughout the lifecycle to ensure that product behaviour will satisfy end users.

Sustainability adds a new dimension that is difficult to handle with standard technology. Designing smart, green products to a high level of product integrity requires investigating a growing number of parameters – such as dimension, materials and operating conditions – to provide designers with enough freedom to meet numerous constraints.

The combination of parametric studies and sensitivity analysis for a

large number of parameters using advanced tools (robust design and optimisation) opens the door to a new era of design.

highlight any prominent female achievers. The entire workforce comprises mostly of males and rarely one can see the ratio tilting the other way. The manufacturing sector is growing at a rapid pace in the country and allied fields are also doing well. At such times, this field should be viewed as one with opportunities by males and females alike. However, due

to lack of sufficient encouragement or prominent names, the demand to pursue a career in this field is lukewarm. The need and growth of this sector is based on large orders from the automobile, defence, aerospace and engineering segments. Thus, opportunities are visible in every sector. Globally, tooling industry seems to be wide and large scale, with 100 per cent contribution of manpower focussed to bring the sector to another level. However, in this regard men continue to outnumber women. But in the near future, can we predict a change in this statistics significantly?

Lack of women in manufacturing Knowledge of Science, Technology, Engineering, and Mathematics (STEM) is widely regarded as critical to be competitive in the current global economy. Due to the unequal ratio of males and females working in this sector, there is a huge disparity in their earnings too. These ratios lead to a less liking for the field in general. In a 2009 survey, only 5 per cent of the girls said they were interested in an engineering career. It should be noted that attracting and retaining more women in the manufacturing workforce will maximise innovation, creativity and competitiveness. Because of our psychological belief that women lack the aptitude to succeed in STEM fields, women in manufacturing careers are considered inappropriate. The idea that girls are

102 MODERN MACHINE TOOLS - June 2011

not good at science is simply floating in the air that we breathe. These false ideas prevent girls and women from pursuing engineering. Such implicit beliefs directly influence parents’ decisions to encourage or discourage their daughters from pursuing science and engineering careers. Hearing or sensing such thoughts and misconceptions in the immediate environment is affecting individual career choices. It simply breaks down a girl’s self-confidence in her abilities. Also, there is lack of female role models in the field of engineering that young females can get inspired from.

Reforms Specific solutions and ways must be implemented to increase the number of women in the tooling industry:  To develop training programmes for girls to focus on machines, technical aspects of programming, and not merely on broader applications  Develop opportunities for women in various departments in tooling industries  Exhibitions or conferences should be held where female employees interact with other engineers

Generating interest Although technology has become more pervasive in the lives of young people, technology as a carrer is

not what they want to pursue when they grow up. According to a recent survey held in the UK, 90 per cent of girls between the ages of 11 and 16 thought computers and cutting edge gadgets are cool, but only 28 per cent of those girls seriously considered careers in the technology industry. Women’s contribution in technology is often taken for granted, merely rolled up as a part of the great tidal wave of innovation surrounding the computer age. The marketing side of technology and services has the potential to become increasingly important in the future. To connect innovative technologies with consumer usages, women will be naturally positioned to be project managers on technology ventures because of experience in other departments and disciplines. Today, if we realise this, we may consider making technology or innovations with a female eye for detail, which would definitely help the society in the long run. While Indian women are making great strides in the field of advertisement, media, education, healthcare, hospitality, etc, surprisingly, until date no Indian woman is at the forefront in the manufacturing sector. Considering that India is emerging as a global manufacturing hub, the issue of skilled manpower needs to be addressed. Hence, courses developed for women will improve the employment potential for women engineers in sectors such as automobile, auto components manufacturing, aerospace, die mould and other industries, thus providing the much required skilled workforce. Women are the real architects of society and the fastest way to change society is to mobilise women of the world. As author Diane Mariechild aptly put, “A woman is the full circle. Within her is the power to create, nurture and transform.”

Cell works the night shift At this aerospace and medical component manufacturer, a Doosan HMC paired with a flexible pallet magazine and cell controller from Fastems has increased production and part quality while eliminating variation throughout the production chain.

E

very night at 12:30 am, the shift manager at Westwood Precision flips off the optional stop toggle on the Doosan cell, makes sure everyone’s gone, turns out the lights and locks the doors. John Landau, production manager at the Everett, Washington-based contract shop, admits it was a bit unsettling at first to leave the Doosan HMC and integrated Fastems pallet magazine running unattended all night. A year and a half after installation, however, he says he’s “amazed” at what the system has done for machine utilisation, which is now close to 94 per cent on a 24-hour clock. In addition to improving productivity, running unattended nearly 24/7 has reduced the time, cost and stress associated with setups while eliminating variation throughout the production chain. The 35-person shop specialises in close-tolerance machining of complex aerospace and The Doosan HP 4000 HMC offers sufficient rigidity to make medical components in heavy cuts at high feeds and speeds small-to-medium lot sizes.

Gordon Nisbet, Company President, attributes the company’s success since its 1982 founding to its commitment to continuous improvement. The decision to purchase the cell – the company’s single most expensive capital investment – last summer in the midst of the recent recession is a testament to that commitment, Nisbet says. “Economic conditions posed a threat, but the slowdown also gave us the time we needed to adapt our company to make it more competitive, more productive, more efficient, more predictable and just all-around better,” he recalls.

Operational Efficiency The company determined that the next step towards meeting those goals was automation. Like those in many other shops, Westwood operators had a long list of steps to check off before hitting the cycle start on any given job. Tearing down the previous setup; switching out the fixtures and subplate; loading and unloading tools; uploading the next program; touching off the first tool; and other, smaller steps in between consumed significant amounts of production

Landau, shown here at the cell controller while Jason Vise works at a setup station, says one of the cell controller’s advantages is remote management. This enables both the company and the three key system suppliers (Doosan, Fastems and the local machine distributor) to upload programs, debug alarms or monitor operations via the Internet

time. Downtime and associated costs were even greater when accounting for shift changes, breaks and the fact that shutting machines down every night essentially amounted to an entire shift of lost production. Work lots, types and sizes all dictated certain basic machine tool and work storage specifications for any new equipment. The targeted work consisted of close-tolerance, prismatic aluminum parts requiring simultaneous X-, Y- and Z-axes movements with anywhere between 20 and 100 tools. Lot sizes ranged from 1 part to 250 or more, but typically between 25 and 100. Typical tolerances were measured in tenths, and surface finish requirements were stringent. Due to the unpredictable nature of its aerospace work, the shop also wanted to be able to set up 30 or more jobs in advance and run any one at a moment’s notice.

Finding the right fit Evaluating these and other requirements led the shop to conclude that it would require a rigid HMC capable of repeating within tenths at heavy cutting depths and high feeds and speeds. That machine would be outfitted with an automated, computer-controlled pallet system. That system would have to be expandable – that is, the shop would

106 MODERN MACHINE TOOLS - June 2011

need the ability to add to the pallet pool when necessary and incorporate new control functionality when available. After careful consideration, the company settled on an HP 4000 HMC from Doosan Infracore (West Caldwell, New Jersey) and an FPM750 Flexible Pallet Magazine (FPM) and cell controller from Fastems (West Chester, Ohio). With a 14,000-rpm spindle, a top feed rate of 1,181 ipm and rapid traverse of 2,362 ipm, the four-axis HMC’s mechanical attributes fit the bill for the shop’s job requirements. On the control side, its Fanuc 31i CNC with AICC Nano Type II high speed software provides 200-block advance position calculation to maintain these high speeds and feeds during simultaneous multi-axis movements. Additionally, the machine’s 30-hp spindle enables it to handle the required roughing chip loads, while its 262-tool ATC has sufficient capacity to minimise tool changes between jobs. The machine was integrated with the three-level, 48-pallet FPM via the combined efforts of engineers from Fastems, Doosan and CNC Machine Service, the local Doosan distributor. The FPM includes a setup station for loading parts and a stacker crane to transport pallets to and from the container. The cell controller offers tool monitoring capability and

stores job packs containing setup sheets, blueprints and other turnkey data for use by employees with password permission. Setup technician Jason Vise was busy prepping jobs for the system long before it arrived. All were alumineum parts because material inconsistencies in ferrous metals could cause problems during lights-out operation, he says. Chosen jobs also consisted of repeat parts with unpredictable schedules. Preparing these parts in advance would enable their quick completion without jeopardising other work. The new cell’s benefits became apparent shortly after production began. Vise says one significant time-saver is the cell controller’s ability to prioritise job scheduling based on key variables, including required delivery, programmed tool life and tool availability. “All of this scheduling is going on in the controller, automatically, based on our entering key variables for each job,” he says. The flexibility that comes with automatic rescheduling based on a complicated set of conditions has reduced inventory and improved cash flow, Landau says. He cites one example in which the control recommended skipping the next job in favour of two different, more urgent jobs. “Based on three job sizes, cycle times and delivery requirements, it determined that we could complete and ship two smaller jobs and still have enough time to run the originally scheduled job without any delay in the required delivery.”

Efficient manufacturing The Doosan HMC offers its own benefits. Landau says the machine’s rigidity facilitates heavier cuts at faster speeds and higher feeds. He recalls one particular job involving close-tolerance housing components that the shop moved from a different machine to the new HMC shortly after it was installed. With the feed-rate override set at

150 per cent, the new machine completed each part in 3 minutes and 45 seconds – 50 per cent less time than the previous machine. Additionally, the ability to run the parts at the higher feeds and speeds recommended for that particular combination of tool and material improved surface finish quality by nearly 50 per cent. Overall cleaner cutting eliminated most of the hand deburring, reducing total cycle time for that secondary operation from more than seven minutes to less than one minute per part. With the previous machine, the shop had to reduce the feed rate to meet tolerances on parts mounted at the top of the tombstone fixture or farthest away from the pallet table. “The cutter was working far enough out from the bearing surface to act like a long lever,” Landau explains. “We had been getting too much deflection between the pallet table and the coupling. On the Doosan, running at a 50 per cent faster feed rate, there was still no deflection.” These gains were particularly notable because the part’s surface included a 3D radius that blends into a straight wall, he says. This required simultaneous X-, Yand Z-axes movements. Much of the cycle time savings were achieved during these moves, which involved toolpath calculations that many CNCs could not handle. In that scenario, he says, the CNC typically suppresses the programmed feed rate. That was a non-issue for the Fanuc CNC and its 200-block look-ahead capability. In addition to improving productivity and part quality, the cell has redefined the company’s notion of what setups should entail, Vise says. Running virtually 24/7 has reduced interruptions and downtime previously associated with change-overs. Landau adds that production control is easier and more effectively executed. “We have eliminated variation at many points in the production chain. We do not see the spikes in production like we used to. We see higher, straighter-line charts, and that is a very good thing.” he concludes

HMCs, turn/mills aid diversification strategy This company had expanded its facility, implemented lean practices and taken other steps to improve efficiency, but breaking into new sectors such as wind energy would require new technology. Two turn/mill machines and two HMCs from Mazak enabled the company to take on new jobs and win suppliers’ confidence for more opportunities in the future.

F

rom the moment of its founding, R&M Mfg has strived to achieve growth through diversification in terms of both services it provides and industries it supplies. Rather than adopting a more conservative posture when revenues dipped in 2009, the company made investments to pursue new business even more aggressively, specifically targeting tough wind energy and aerospace work. Lean implementation, a facility expansion and other such efforts brought the company a long

108 MODERN MACHINE TOOLS - June 2011

way towards reaching its goals, but the true difference-maker was an investment in two turn/mill machines and two large HMCs from Mazak (Florence, Kentucky).

The initiative Based in Milton, Wisconsin, R&M was founded in 2004 when Mark Merk received word that the automated assembly equipment manufacturer where he had worked for 25 years would soon close. Similarly to R&M’s later efforts to invest amid a dire recession, Merk saw opportunity in a situation that would likely cause others to despair. “At age 50, I did not want to have to move my family in pursuit of a job, and I knew that a lot of other people affected by the plant closure felt the same way,” he recalls. Enter R&M, a provider of precision machining, engineered assembly and fabrication services. To start the business, Merk purchased a facility with 20,000 sq ft of floor space and 2,000 sq ft of office space, along with much of the equipment used in the former plant. The company’s first 10 employees were handpicked from the most talented and experienced of those who had recently been laid off from his former employer. Two years later, that initial workforce had doubled amid a steadily increasing revenue and customer base. In 2008, the company

was purchased by a customer, David Underwood, and Merk shifted to the role of Vise President of sales. Thanks in part to an increased emphasis on sales, the company ended that year with $ 11 million in revenue, compared to $ 2 million when it started four years earlier.

Embracing challenges Despite this success, 2009 would bring substantial challenges to further growth. Seeking to offset reduced order quantities resulting from the economic recession, R&M recognised opportunities for new business in wind energy and aerospace. However, breaking into those sectors would be difficult because many of those jobs are shifting toward exotic materials with tight tolerances and complex geometries. Additionally, it seemed customers were moving to shorter and shorter turnaround times. “We used to have seven to ten days to provide a quote, and then the customer would want delivery in eight weeks. Now, they want a quote within two days and delivery in two to three weeks,” Merk recalls.

110 MODERN MACHINE TOOLS - June 2011

In response, the company expanded the facility to 45,000 sq ft - more than double its original size - obtained new ISO certification, and implemented a 5S project and other lean initiatives to reorganise and streamline operations. Despite these efforts, it soon recognised that it would need new machining technology to set itself apart from similar operations by pursuing tough energy and aerospace work. Specifically, the company determined that it required a pair of HMCs to replace outdated models. It would also need a pair of turning centers with milling capabilities that could meet stringent tolerance requirements and combine multiple operations on one platform. All of these machines would need the capacity to handle large parts. In December 2009, the company took delivery of a Mazak Quick-Turn Nexus (QTN) 350 MY turning center. The next month, that machine was followed by a QTN 450 MY turning center and an HCN 6800 HMC with a Palletech automation system. An HCN 10800 HMC completed the quartet in March 2010.

In addition to high precision, Merk says the turning machines’ greatest benefits are their Y axes and live tooling, which enable combining multiple operations on a single platform. The horizontals, which replaced older models at R&M, feature heat compensation features, software packages and other technologies not available even a decade ago. Merk says the machines’ integrated Palletech pallet systems are especially useful for saving time. “One can stage 24 different jobs, hit the cycle start button and walk away,” he notes. Merk cites one project for the Department of Defense as an example for the sort of work the shop has been able to pursue since investing in these machines. The job involves parts made of a special grade of steel that require tolerances ranging to ± 0.0003 inch and 30-Ra surface finishes. In the past, these complex components would have required operations across a series of machines. Now, the company can machine the parts complete with only two: the HCN 6800 and QTN 350 MY. “A lot of that is due to the live tooling and Y-axis capabilities on the QTN 350 MY, which eliminate a substantial amount of set-up time,” Merk explains. As for the company’s foray into wind energy work, Merk cites a family of large bearing sleeves that fit to the main shaft of a system’s generator. The 4140 steel components can be as heavy as 1,500 lbs and as large as 6 feet in length and 15 inches in diameter. Each part’s Inner Diameter (ID) and Outer Diameter (OD) must be machined to within ± 0.0005 inch, and they require 20-Ra surface finishes. The sleeves were previously produced by another manufacturer, which would machine the parts to within 0.01 inch before sending them out for finish grinding to meet stringent OD and ID requirements. “We analysed the cost of these parts and realised that about 50 per cent of it stemmed from the outsourced grinding. If we

could eliminate that we could provide enormous savings to the customer,” Merk recalls.

Viable option The company found that in addition to meeting the tolerance and surface finish demands, which eliminated the need for grinding, the QTN 350 MY could machine each bearing sleeve in a single operation. Demonstrating

this achievement to the wind-systems producer not only won the job, but also started a relationship that continues to pay dividends, Merk says, “We drove a lot of savings to that particular customer, so they took a harder look at us. Since then, the opportunities have not stopped.” Although the new machines were chosen primarily based on the technical capabilities necessary for the jobs R&M wanted to pursue that was not the only reason the company chose Mazak over other builders. “They have made a clear commitment to our success, and that adds a whole other layer to the benefits we receive from the technology,” says Underwood. More specifically, he notes that the builder quickly responds to service calls and works to maintain a relationship with the company. He further adds, “There are a lot of days when I will come in and a Mazak rep will be on the floor. I will go down to see if there was an issue he was

responding to, but it will turn out that he just had some free time and wanted to stop by and do some continuing training with our operators.” The builder’s training services, which R&M has leveraged to crosstrain much of its workforce, are especially valuable, he adds. As a result of this training, every shopfloor employee can run at least two different types of machines, and 75 per cent of the workforce can operate any machine. Broadening employee expertise improves flexibility and makes the company more likely to succeed in machining challenging parts than similar smaller operations, establishing a strong position as the economy continues to recover. “We are in an arena where we are playing with the big boys. There are not too many shops like ours that can quickly and accurately machine extremely high-tolerance parts. Mazak helps us participate in that market,” Underwood concludes.

Long-lasting insert turns around tough Inconel job By changing to a hex-shaped turning insert with a 45-degree lead angle, this shop saved thousands of dollars on a difficult Inconel turning application.

W

hen inserts rupture in Inconel, the typical reaction is to “take the load off” the insert by lightening the cut, says Jim Whitley of cutting tool manufacturer Ingersoll (Rockford, Illinois). However, this reaction may be ill-advised. Shops tend to forget that rupture often begins with an edge going dull, which, in turn, overloads the insert to the point of breaking down. “This can happen within a few seconds, so it is easy to miss wear as the root cause,” he explains. “Assuming that adequate machine horsepower is available, the better answer is to go to a stronger insert with a gentle lead angle and make fewer, deeper passes.”

Following Whitley’s advice paid dividends at Scot Forge, which saved $ 2,400 per part on one tough Inconel turning application after retooling to Ingersoll’s Hex-Turn inserts and adjusting machining parameters accordingly. Based on its success with that job, the company has standardised on Hex-Turn and those same parameters for rough turning a growing variety of Inconel parts. Scot Forge is a diversified, employee-owned forging company that has been in business for more than 100 years. It has plants in Clinton, Wisconsin as well as Franklin Park and Spring Grove, Illinois. By customer preference, most of the company’s output is delivered in the forged and rough-machined condition.

Quest for the best practice

Thanks to a 45-degree lead angle and top-face chipbreaker, the Hex-Turn inserts outlast their predecessors by 69 to 1 while reducing cycle time on the Inconel forging by 15 hours

112 MODERN MACHINE TOOLS - June 2011

Howard Dempsey is supervisor of the machine and saw shop at the Clinton plant, a site that runs 24 hours a day, five days a week and houses 200 employees, 50 of whom are machinists. He says the part that prompted the company’s switch to Hex-Turn is just one of a growing number of jobs involving high-temperature alloys, which management has identified as a trend. “We get about six reorders a year for that part, and orders for other Inconel and titanium forgings are rising,” he notes. “So, we decided it was time to develop the best practice for machining them.” Taking orders on Inconel, titanium and other high-temperature alloys provides a competitive advantage

Scot Forge’s Brandon James indexes a Hex-Turn insert, which will last reliably through the entire machining process on the big Inconel forging. The shop’s previous, square inserts typically failed after just one inch of feed

and a source of pride, since these exotic materials are abrasive to tools and impose high cutting forces. Additionally, they tend to generate hot, stringy chips that can stick to the cutting edge and overheat the tool. As a result, such work can create bottlenecks, tie up machines and increase tooling costs. That was the case with Scot Forge’s problem component, a huge Inconel No 7718 hub used in nuclear turbomachinery. This part requires rough turning and facing to remove about 0.8 inch of material across its entire diameter, primarily for truing up. As forged, it measures 98 inches in diameter, with a step-down to a 93-inch diameter on one end. Previously, machining took 105 hours and 40 passes at a feed rate of 0.02 ipr, a cutting depth of 0.075 inch and a speed of 38 sfm. The turning and facing operations required different inserts, and the job typically ate through 69 inserts per part. In fact, tool failure was so prevalent that inserts required indexing every half inch, and the job had to be run 100-percent attended. Moreover, the main failure mode was edge rupture, which renders the insert useless even if some edges go unused. All the while, the operation tied up a large vertical lathe from MAG Giddings & Lewis (Fond du Lac, Wisconsin) that the company needed for other work.

Future prospects

Ingersoll’s Raymon Avery and Scot Forge’s Howard Dempsey stand amid finished Inconel hubs while discussing how to tackle the next tooling issue. Avery or his colleague Jim Whitley meet regularly with Scot Forge representatives to stay ahead of the curve in production planning

114 MODERN MACHINE TOOLS - June 2011

With an eye toward a better standard practice for turning this class of alloy, Dempsey asked all his tooling vendors for their best ideas and began testing different solutions. Most tools the company tested produced minor improvements at best. The exception was the Hex-Turn, which features a 45-degree lead angle presentation and top-face chipbreakers. Tests showed these inserts could significantly improve cycle time and tool life compared to the square, flat-topped, zero-lead models the shop had been using.

The company standardised parameters for the new tool at an 0.015-ipr feed rate (slightly less than the previous rate), an 0.15-inch cutting depth (double the previous setting) and a speed of 60 sfm (60 per cent higher than the previous setting). Despite more than doubling the cutting rate, each insert lasted through the whole part. Cycle time dropped 15 per cent. “We would have been happy with just the tool life improvement,” says Dempsey. “The throughput gain was an unexpected bonus.” Cutting deeper reduces the number of required passes, which, in turn, reduces the insert’s exposure to the hot, abrasive environment at the cutting edge. However, as Whitley explains, an insert’s ability to withstand a deeper cut depends on its strength. That’s why—true to its name—the Hex-Turn features a hexagonal geometry, a shape that is second only to round inserts in strength, he says. Ingersoll product manager Raymon Avery adds that the other difference-maker is the 45-degree lead angle, which is made intrinsically possible by the insert’s hex shape and chipbreaker top face. This lead angle provides a gentler entry into the work that reduces cutting forces and protects the insert. Meanwhile, the contoured top face breaks up the long, hot, gummy chips characteristic of Inconel alloys and deflects them away from the insert to reduce heat. In all, the drop-in retooling saved $ 1,500 in cycle time and $ 900 in tooling costs—per part. Cost savings aside, having a secure process for such difficult material enables Scot Forge to bid more confidently on Inconel jobs and to compete more effectively in a high-tech niche. “This improvement enables us to maintain competitive costs for machining Inconel,” says Dempsey. “Otherwise, we would have been forced to raise prices to cover the excessive cost of tooling and the resulting sub-par productivity.”
