Upfront Blame Canada Once again, Canada’s productivity (or more accurately, lack of productivity), is in the spotlight.

Many in the manufacturing sector, including Canadian Metalworking, have commented about Canada’s productivity lag when compared to other countries such as the US. The discussion has been ongoing for decades because productivity has been an issue for just as long.

The most recent comments come from Scotia Capital economist Aron Gampel. Commenting in an online Globe and Mail article, he says Canadian productivity “should be a go-go, but still a no-go.” He cites the higher cost structure (labour costs) in the Canadian manufacturing sector as the top culprit.

Others have cited multiple reasons to explain the ongoing productivity gap—the strengthening Canadian dollar, the growing emergence in North America of low-cost offshore competitors from emerging markets in Asia, and poor investment efforts in machinery and equipment and research and development.

The government has attempted to address the gap through varied measures, to no avail. The productivity gap has continued to widen and some suggest realistically, Canada may never be able to close it.

Last year, The Conference Board of Canada noted in its Forecast 2010, “Canada will have a difficult time trying to close the productivity gap with the United States. Evidence has shown that countries with lower levels of productivity not only have to grow faster to catch up, but they have to maintain faster growth for an extended period of time.

“If US productivity grows by its 2008-2009 annual growth rate of 1.67 per cent over the next 15 years, for example, Canada’s productivity growth will have to be 3.22 per cent per year to eventually match the US productivity level. That’s a near-insurmountable four times Canada’s annual productivity growth rate between 2000 and 2008. Closing the productivity gap with the US is essential to closing the income gap, but Canada is going in the wrong direction.”

How can Canada change direction? That’s a question many have attempted to answer, but so far, most of the measures—more investment in new machinery and equipment (think government extensions on the Accelerated Capital Cost Allowance), more investment in research and development and more efforts for training a more technically advanced workforce—have not appeared to work.

If indeed these are the ways to improve productivity in Canada, why haven’t these measures worked? Why is it this country’s productivity has consistently lagged? As far back as the 1970s, labour productivity grew 1.4 per cent annually compared with the US average of 1.5 per cent.

That’s not a huge difference, but US productivity growth has remained relatively stable in recent decades, while Canada’s growth has dropped 0.9 per cent per year on average, according to data from The Conference Board of Canada.

What are your thoughts on productivity in Canada? Do you think something can be done to improve the productivity gap? Do you think the issue has been overblown by industry pundits?

I would welcome your comments on the issue.

News Joint machine tool distributor event returns to Ontario

For the sixth consecutive year, several machine tool distributors will join together for the largest open house of its kind on May 4 and 5.

The Joint Open House has become somewhat of a tradition among Ontario manufacturers searching for machine tools. Six years ago, Ferro Technique, Elliott Matsuura Canada, EMEC Machine Tools and MAG decided to work cooperatively and host a joint open house for customers. The event was a hit with local area manufacturers.

This year, machine tool distributor participants include three of the original companies—Ferro Technique, Mississauga, ON; Elliott Matsuura, Oakville, ON; and EMEC Machine Tools, Mississauga, ON—as well as DMG Canada and SSTCanada, both based in Mississauga, ON. Similar to last year, a total of more than 50 machines, ranging from standard three axis to multitasking, will be under power during the two day event.

Brian Donnelly, vice president of Ferro Technique, says he and his colleagues expect to see 500 to 600 people this year. Last year approximately 350-400 manufacturers attended the event, but given the improving economic climate and the rising machine tool orders he and his colleagues are witnessing, “we should see more people this year.”

Another reason why more people may attend this year is because of the distributors’ plan to offer bus service to and from the far eastern and far western parts of the province.

“From the eastern end, we’ll likely have a bus that goes to Kingston with stops along the way back to the area and in the west, from Windsor, we’ll have stops in Chatham, London and Woodstock,” says Donnelly.

Mori Seiki, Ellison Technologies open new Canadian technical centre

Mori Seiki and its distributor Ellison Technologies will celebrate their Canadian partnership with the grand opening of their technical centre in Mississauga, ON, April 27 and 28.

The event will be used for the Canadian debut of Mori Seiki’s NVX5080 vertical machining centre from the company’s new X-Class. Other machines on display will be the NMV5000

8 | APRIL 2011 | www.canadianmetalworking.com

DCG five axis vertical machining centre, the NT10000/SZM mill turn centre and the NL2500SY CNC lathe.

As part of the two-day event, a lean automation cell will demonstrate how manufacturers can run unattended operation to increase machine utilizaton and machining capacity.

Technical demonstrations will highlight new technologies for automotive and energy markets, and multi-tasking strategies.

The new facility is located at 6497 Edwards Blvd. in Mississauga, L5T 2V2. For event details and registration, visit the event web site at www.ETGrandOpening.com or call 877765-1331.

New metals research lab

Canadian manufacturers involved in research and development now have a new resource for metal technology, a new metals research lab that opened its doors earlier this year in Hamilton, ON.

From left: Dr. Patrick Deane, president of McMaster; Christian Paradis, Minister of Natural Resources; David Sweet, MP, Ancaster-DundasFlamborough-Westdale; and Zach Douglas, president of McMaster Innovation Park.

The CANMET Materials Technology Laboratory (CANMEtMTL), which has relocated from Ottawa to Hamilton, is a $40-million, 145,000 sq ft lab that will operate under the federal government’s Natural Resources Canada department and conduct research into structured metals and alloys, materials design, pilot-scale processing and performance evaluation.

The lab was relocated to Hamilton’s McMaster Innovation Park to be closer to the province’s manufacturing hub.

“CANMET’s move to McMaster Innovation Park represents a huge boost for the region’s and country’s economic development and prosperity,” said Patrick Deane, president of McMaster University. “Its central location in the heart of the manufacturing sector, combined with its proximity to McMaster’s research facilities and expertise, has created a dynamic materials and manufacturing research cluster. Not only will this help to keep Canada’s industries competitive on the global scale, it will ensure that we attract and train the best students and researchers.”

both industry and government.”

While the prevalence of counterfeit parts in the supply chain is difficult to quantify, in fiscal 2009, the US Customs and Border Protection Service seized nearly US$4 million in counterfeit critical technology components, including networking equipment and semiconductor devices that the aerospace industry uses.

Event to give manufacturers leg up in marketplace Mazak Corp. Canada wants to give manufacturers a competitive edge and is holding a special event—Discover Mazak-Canada—to highlight the technologies and technical know-how that it takes to be successful in today’s market.

The event is slated for May 4 at Mazak Canada’s headquarters in Cambridge, ON. In addition to machine tool demos—including Mazak’s “Done-in-One” multi-tasking concept on various machines and five axis simultaneous machining—the event will feature keynote speaker presentations such as “How to do Business with Bombardier.” There will also be presentations on how manufacturers can take advantage of Ontario government grants and financial assistance for capital acquisitions and business expansion.

Aerospace industry says it’s concerned about counterfeit parts in new report

The volume of counterfeit parts in the supply chain is increasing, with potentially catastrophic consequences.

“The use of counterfeit parts in the aerospace industry may have life or death consequences,” says Aerospace Industry Asociation (AIA) president and CEO Marion Blakey.

“Reducing their proliferation and potentially harmful effects requires increased diligence and active control measures from 10 | APRIL 2011 | www.canadianmetalworking.com

A new report by the AIA “Counterfeit Parts: Increasing Awareness and Developing Countermeasures”, seeks to raise awareness of the issues associated with counterfeit parts.

“Regardless of how counterfeit parts enter the aerospace and defense supply chain, the ramifications can be significant,” says Blakey. “They can jeopardize the performance, reliability and safety of our products.”

While profit is the primary incentive for counterfeiting, the long lifecycle of aerospace products also contributes to conditions that make aerospace and defense equipment susceptible to counterfeiting. Aircraft developed in the 1950s, such as the B-52, are still in active inventory while parts from original equipment, component manufacturers or authorized aftermarket manufacturers or distributors may no longer be available.

The report makes more than 20 recommendations for industry and government that encourage further discussion among stakeholders on how to most effectively reduce counterfeit parts in the supply chain. The recommendations were prepared by AIA’s Counterfeit Parts-Integrated Project Team and include: • Scrutinize the purchasing process to limit the use of automated systems, which increases the risk of counterfeit products.

• Develop an Approved Suppliers list for use by government and industry.

• Companies develop a counterfeit parts control plan that documents the processes used for avoidance, detection, risk mitigation, disposition and reporting of counterfeit parts.

• Conduct training for employees in the areas of procurement, detection, reporting and disposition of counterfeit parts.

• Create standards in the area of mechanical parts and materials.

Government coffers flowing: Election time?

A federal election has yet to be called, but if the recent slew of government funding announcements for the manufacturing sector are any indicator, we may be heading into a fall election.

The majority of the funding announcements are for manufacturers in Quebec, an even stronger sign the government is trying to win votes in a province that has not had much love for the Conservative party in the past two decades.

On March 21, the government announced more than $1.6 million in federal funding for two organizations: $915,000 for start-up bus manufacturer Autobus Lion Inc., Saint-Jerome, QC, to build a manufacturing plant; and another $731,250 for Aero Montreal, a public-private partnership think tank (founding member of the organization is Bombardier Inc.’s president and CEO Pierre Beaudoin) with a mission to boost Quebec’s aerospace sector’s competitiveness on the global market.

And in Rouyn-Noranda, QC, MBI Produits Dimantes Group, a manufacturer of large diameter drill stems for the diamond drilling sector, received $107,153 in repayable funding (through the government’s Community Adjustment Fund) for the acquisition of specialized equipment. Specifically, the company plans to purchase a digitally-controlled lathe to expand production.

Soudure Saint-Gabriel, Saint-Gabriel-de-Brandon, QC, a manufacturer of steel dump bodies for trucks, plans to use its $198,000 repayable funds to expand its manufacturing plant with the purchase of new production equipment and the addition of a paint finishing operation.

Abmast Inc., Saint-Hyacinthe, QC, a manufacturer of bonded grinding wheels for machining centres, received $400,000 (the company is investing an additional $1,160,000) to improve its production operation. It plans to automate its production of grinding wheels with the purchase of new automation machinery.

In Saint-Claire, QC, Laforo Iron Foundry will soon be expanding its operation with the purchase of new equipment after it received $330,000 in repayable financial assistance through the federal government’s Business and Regional Growth program.

Not all the funding announcements were for the Quebec manufacturing sector. Earlier this month, Manitoba’s manufacturing sector got a $5.9 million dollar boost when the federal government announced funding for Red River College, Winnipeg, MB, to expand testing facilities for the province’s aerospace, transportation and general manufacturing sectors.

And in Belledune, NB, the government announced it would provide $1.5 million to the Port of Belledune to help fund the construction of a metal fabrication facility for producing and storing pre-assembled steel units. The new building will be equipped with 20 ton overhead cranes, welding equipment and other metal fabricating equipment.

There are likely to be more federal government funding announcements in the coming months as the government continues to establish goodwill among voters in Canada’s manufacturing sector.

Exports spur growth: RBC Economic Outlook At press time, the federal government had announced it would be providing funding for another manufacturer, Produits Metalliques Bussieres, Saint-Henri, QC, a metalworking job shop profiled by Canadian Metalworking last year.

Another big recipient of government funding is Technologie InovaWeld Inc., La Pocatiere, QC, a laser welding and laser cutting manufacturer of stainless steel and aluminum products.

The company received $450,00 in repayable funding under the government’s Business and Regional Growth program to acquire new equipment. It received an additional $200,000 from Canada Economic Development through the Kamouraska Community Futures Development Corp. The company plans to expand into the aerospace, transportation and agri-food markets.

12 | APRIL 2011 | www.canadianmetalworking.com

In yet another sign the economic downturn is fully behind us, a new economic outlook report released today by RBC conomics says Canada’s economy finished the year with stronger than expected gains and will continue to grow through 2011 and 2012.

The most significant gain came from net exports, which added 4.5 per cent to the 2010 fourth quarter gain. RBC says consumer spending also helped spur growth in GDP, “marking the fastest increase in spending since late 2007,” it notes in the report.

RBC expects real GDP to increase 3.2 per cent in 2011 as US demand for Canadian exports increases. Growth in 2010 is forecast to rise by 3.1 per cent. “We expect net exports to continue to bolster economic growth in 2011 and 2012, as long as demand for motor vehicles and commodity-related

News products remains robust. These industries account for two thirds of Canadian goods sold abroad,” says Craig Wright, senior vice president and chief economist at RBC. He expects to see the Canadian dollar remain strong throughout 2011, due in part to a rise in commodity prices and adds that the strong dollar will “support Canadian businesses importing capital equipment to improve productivity growth.”

RBC Economics expects labour market conditions to remain firm in 2011 with disposable income expected to post a 4.1 per cent gain, providing support to consumer spending.

“Consumers’ earlier confidence in taking on increasing amounts of debt was based on a combination of lower interest rates, a strengthening labour market and a 4.6 per cent rise in disposable income,” says Wright. “An expected slowing in the housing market, rising interest rates and tightening mortgage lending standards all add up to a leveling out in consumer debt relative to income.”

RBC has remained optimistic on the US economy, projecting growth of 3.4 per cent in 2011 and 3.6 per cent in 2012. The expectations reflect the passage in that country of a tax cut package in December, continued labour market improvements, low interest rates and “tame underlying inflation (when measured in consumer prices).”

Japan crisis: Special online report

The earthquake and subsequent tsunami that hit Japan on March 11 devastated parts of the country, but most Japanese suppliers to the North American metalworking industry were fortunate and experienced few production disruptions.

Many of the world’s major machine tool builders—Mazak, Makino, Matsuura, Mitsui Seiki, Mori Seiki and Okuma—and some cutting suppliers—Mitsubishi Materials, Sumitomo Electric Carbide and Tungaloy—have corporate headquarters and production facilities in Japan.

Canadian Metalworking Online contacted many of these suppliers to learn what impact the crisis was having on suppliers and the long term effects.

News Floor Space Have you ever used email to send a quote to a potential customer or do you always phone?

“I only use email to send potential customers quotations as this allows both parties to have something to refer to.”

-Renny Husada, vice president, Yess Products, Surrey, BC

“We email 90 per cent of our quotes to our clients. We sometimes call to see if there are any questions from the 10 per cent of our clients who don’t use email.”

-Steve Cotton, president, Micro Precision Parts Manufacturing Ltd., Vancouver Island, BC

“Quotes are prepared for “potential” customers using our internal E2 Shop System and sent to them via email.

However, our practice is to make a personal connection with a potential customer and discuss their needs to ensure that we fully understand their requirements and expectations. Like all business transactions, there is an element of relationship building that requires personal contact. The quote is always negotiable.”

-Ron Marks, president, Techtronics Machine Works Ltd., Musquodoboit Harbour, Nova Scotia

“We always use email.”

-Jason Bannerman, president, Xakt Komponents, Brampton, ON

“Most our quotes are done by email, but if it’s a potential new customer, we always phone first to make sure we understand the requirements, chat them up, etc.”

-Soren Holm, president, Soren Holm Inc., Mississauga, ON

“We try to use different avenues. What we used to send by fax, today we send roughly 50 per cent fax, 50 per cent emails. Some customers prefer emails, while others still want fax. Nothing beats face-to-face discussion when possible.”

-Marco Gagnon, co-owner, Gagnon Ornamental Works, Grand Falls, NB

“Most of our quotations are by email with the occasional fax.”

-Peter Alden, co-owner, Wessex Precision Machining Ltd., Ayr, ON

“About 80 per cent of our quotes are sent to us via email then followed up with CAD sent via FTP or email but almost all of the time quotes are sent to customers via email. Only once every so often, a customer requests to have us send the quote with the good old fax machine. As paper is easily lost and is difficult to track, not to mention killing trees, most of our clients prefer the email method. No quotes are sent by phone unless it is an “unofficial” estimate.”

-Adriano Oppio, vice president, Classic Tool & Die, Oldcastle, ON

“We predominantly use email to quote. It is a quick and easy way to get the information to your customer. A follow-up phone call is made to ensure that the customer has received the quote and then we answer any questions he/she may have. We have found it to be very effective.”

-Debbie Blowe, systems manager, Vibra Finish, Mississauga, ON

“We only use email.

Most people send us a drawing [via email] ... we reply back to that same address with pricing and delivery.

This way we have the quote in writing and the customer has time to review. This works very well for us and our customers seem to be very comfortable with it as well.”

-Larry Stuyt, president, Ontario Laser Cutting, Tillsonburg, ON

“Always email,”

-Rob Muru, president, A-Line Precision Tool, Toronto, ON

“Email is our primary method of delivering significant quotes. We do quote a lot of small stuff over the phone.

Aerospace takes off

30,900 new planes; a $3 trillion-plus global market over next two decades

By Nate Hendley ..................................................................................................................................................

In mid-February 2011, officials from the Aerospace Industries Association of Canada (AIAC) and various aviation firms went on a seven-city, cross-country tour. The assorted group met with the media and local boards of trade and economic development in each city they hit in the first-of-itskind campaign.

“Our objective is to inform Canadians about our industry.

We need to do a better job letting Canadians know that [aerospace] is an industry that’s good for the whole country,” says Maryse Harvey, vice president public affairs at the Ottawa-based AIAC, which represents some 400 firms.

Touring aerospace officials also hope to impart a message of hope about their sector.

“The future looks bright,” insists Harvey.

Boeing’s annual market forecast—echo this view. Both acknowledge the recent recession has wrecked havoc with the industry (global passenger air travel declined two per cent in 2009, says Boeing). The same reports, however, paint a rosy future, with dramatic increases in air travel, plane orders and aerospace revenues.

As commissioned by the AIAC, the Deloitte and Touche study, entitled The Strategic and Economic Impact of the Canadian Aerospace Industry, was released October 2010.

The report puts Canadian aerospace revenues at $22.2 billion in 2009 (last year for which numbers are available) and employment at 78,965 people. This represents a decline from 2008 when revenues were $23.6 billion and employment stood at 83,000. Deloitte and Touche predicts a quick turnaround, however, and forecast revenues of $24.1 billion with employment at 82,956 in 2010.

AEROSPACE & DEFENCE

While JSF is an international effort, SADI is a Canadian government program, launched April 2, 2007 with the aim of pumping funds into aerospace, defence, space and security R&D. In December 2010, Longueuil, QC-headquartered aerospace giant Pratt &Whitney Canada (a division of the US parent firm) announced it was investing $1 billion for R&D on new aircraft engines. Some $300 million of this investment came in the form of a repayable SADI loan.

Industry Minister Tony Clement said Pratt & Whitney’s initiative had the potential to create thousands of jobs over the next few years. Pratt & Whitney’s research will focus on reducing fuel consumption, emissions and noise in engines for business and regional jets and helicopters.

The drive for more fuel efficient, environmentally friendly aircraft technologies is part of a “key technological trend” in the sector, notes the Deloitte and Touche report.

Other aerospace firms have also landed sizeable contracts in recent months.

Montreal-based Bombardier announced a US $446 million deal in December 2010, with SpiceJet, an Indian company.

SpiceJet ordered 15 Q400 NextGen turboprop planes and optioned an additional 15. Should SpiceJet convert the options to firm orders, the deal would rocket up to US $915 million in value.

In February 2011, meanwhile, Bombardier penned a deal worth $175 million with Quebec firm Heroux Devtek to make structural components for airplanes.

CAE, a Montreal company that makes aircraft flight simulators, announced in January 2011 it had landed a recent series of contracts worth a total of $140 million to provide flight simulator and training technology to militaries in 12 countries.

It’s this kind of bustle that prompted a highly favourable conclusion from Deloitte and Touche.

Canada “has the potential to double aerospace employment by 2020,” states the report.

Such optimism is also apparent on the shop floor, among companies that service the aerospace sector.

These firms include A-Line Precision Tool of Toronto where 80 per cent of the workload is aerospace-related, says

INDUSTRY REPORT

company president Rob Muru.

A-Line makes “engine parts for supersonic platforms, engine parts for future development engines, radar invisible engine parts, helicopter gear parts, submarine search equipment on helicopter platforms, etc.,” says Muru.

A-Line’s website (http://www.a-linetool.com) describes the firm as “a proud supplier of critical components for the world’s most advanced [jet] fighters and weapons systems.”

To highlight this commitment, the site contains pictures of Chinook military helicopters, the F-117 Nighthawk fighter and the JSF F-35.

Muru frets about competition from offshore locales: “You are on drugs if you are not concerned about competition from offshore,” he states.

That said, he’s anticipating more aerospace work in the near future.

John Saksun Jr., president of Queensway Machine Products (QMP) in Toronto says much the same. Founded in 1952, the shop has 45 machine operators and roughly half of its business is in aerospace. It manufactures structural aluminum, steel and titanium parts, primarily for tier two aerospace companies.

Saksun Jr. says the aerospace part of his business “has been a bit in neutral in the last couple years ... I believe that it is starting to engage and we are doing more than in the past ...

I do believe that we will get more as things pick up, maybe in the next six months.” CM Nate Hendley is a regular contributor and freelance writer based in Toronto.

AEROSPACE CASE STUDY

30,000 ft High When your machined components are flying 30,000 feet in the air you better have the right equipment for the job

Most components machined in shops around the world call for reliability in the end product, but few demand the absolute confidence of performance as those produced for the aerospace industry. Nowhere is this better understood than at Mesotec Inc., a manufacturer of precision aircraft components based in Sherbrooke, QC. The company, that counts Bombardier Aerospace and other leading aerospace OEMS among its customer base, will take in an estimated $15 million in sales this year.

Alec van Zuiden, Mesotec’s president and CEO, commands the helm of the company with a management strength forged through years of practical experience and tempered with a proactive philosophy toward resource optimization.

The first phase in optimization according to Van Zuiden involves the employees. “It comes down to empowerment,” he says. “Let the people do what they have been hired to do. This is difficult for a lot of managers. People tend to set up little structures around themselves for self-insulation while still making it easy for them to look over everyone’s shoulder and micromanage. You have to make sure they have the proper training for the job and then show them you have confidence in their performance. We have more than a hundred people working here. It’s important that I make it a place where they can grow to meet their personal objectives as well as my corporate objectives, and then we have a winning team environment.”

The second phase in Van Zuiden’s optimization involves the equipment in the hands of Mesotec’s trained and experienced employees to produce the company’s output of precision components. Raw materials coming into the 32,000 sq ft plant are first marked for traceability, an important step for the aircraft industry. Materials then travel either to machining cells dedicated to a particular customer’s parts, or to machines set up to handle specific operations, such as bore milling large components, plunge or wire electrical discharge machining tools and fixtures, or grinding round engine-related parts. The accuracy of parts is verified using a wide range of inspection devices, including two computerized coordinate measuring machines.

THE PRODUCTION OPERATION

To keep up with the aircraft industry’s demand for tighter tolerances on many of the machined components’ dimensions, Mesotec purchased a jig boring machine in August 2009, the 6CN-II jig borer from Mitsui Seiki USA, Franklin Lakes, NJ, an approximate $900,000 investment.

In addition to the jig borer, the company operates a turning manufacturing cell—which is now a Centre of Excellence for the 22 | APRIL 2011 | www.canadianmetalworking.com

This landing gear part has two holes bored to 0.0005 in. diameter and to within 0.001 in. in line of each other on the Mitsui Seiki jig borer.

production of seal runners for Pratt & Whitney—and includes three and four axis Mori Seiki lathes and a cylindrical grinder.

Another cell, used primarily for tooling and development work, includes four, three axis Hurco milling machines. Van Zuiden says the company is looking to add a fifth Hurco machine in this cell.

At the time of publication, the company was in the process of installing two additional cells, one dedicated to the production of aircraft engine parts which will include three, four and five axis milling machines, and the second will be for large (two meters long) structural parts on five axis machining centres.

“We have many of the machines in place, but we’ll probably be purchasing more equipment,” says Van Zuiden. “We have a budget with a capital expenditure of $1.8 million; that’s what we expect to spend on machinery.”

When asked about the new jig borer’s capabilities, Daniel Rheaume, Mesotec’s technical sales manager, referring to one of the parts currently being processed on the machine, says “that part is one of a pair of matching components that hold the landing gear in place on a commercial aircraft. They come in to us as right and left-hand 70-series aluminum forgings.

We do most of the rough and finish machining of the contours and surfaces on a five axis machining center. Then we send them out for shot peening.”

Many of the machining processes required for producing aerospace components can result in tensile stress that can lead to part cracking or stress corrosion, reducing component life. In shot peening, spherical particles of one of several

industry report

media are blasted at the surface of the component, which creates a continuous layer of compressive stress. This replaces the tensile stress and prevents fatigue stress and stress corrosion from starting.

“After shot peening,” explains Rheaume, “we bring them back in-house and put them on the Mitsui Seiki for boring two critical in-line holes. The required tolerance on the drawing is very close, one thousandth of an inch, but we give ourselves even closer tolerance, five ‘tenths,’ to make it easier for us at assembly. The relationship of the two holes to each other requires three thousandths in-line tolerance, but we keep it to within one thousandth so we don’t have to worry about re-machining the bushings when the part gets to assembly.”

After the landing gear components are jig bored on the Mitsui Seiki jig borer, they are sent out to be anodized, primed and top coated. Once back at Mesotec, the bushings are installed and the part is inspected to ensure accuracy conformance. “Since that part holds the landing gear, maintaining precision while machining is very important,” says Rheaume.

Another pair of parts set up on the Mitsui Seiki are large 70-series aluminum forgings, each 30 in. by 48 in., (762 mm x 1, 219 mm) that will constitute two sides of the assembly that hold the front landing gear on a business aircraft. Again, the part is first machined, contours and surfaces, on a five axis machining centre, shot peened and then put on the Mitsui Seiki to have two holes bored. Tolerances are held to 0.001 in. diameter and 0.002 in. true position. It is important that the holes align perfectly for the landing gear shaft that passes through them.

“The new jig borer has become an important piece of equipment for us,” says Reaume. “Before we had it, we might have gone back and forth between a machining center or grinder and a coordinate measuring machine two or three times to make sure the part was good. On the Mitsui Seiki, the part is good the first time, every time. That’s a great advantage of the jig borer on production parts. On some parts where we have to machine multiple holes or slots, as many as 20 or 30 at a time, going back and forth between the machine tool and the CMM is extremely time consuming.

Holes on this landing gear component are machined to within .002 in. true position of each other on the company’s new precision jig borer for perfect shaft alignment in final assembly.

two arc seconds of straightness achieved in all axes. Mitsui Seiki measures ballscrews for “drunkenness,” which is the theoretical path versus the actual ball path. This helps eliminate deviation that could cause wear that results in negative positioning characteristics over time. The machine is also equipped with a patented bearing lubrication system for spindles.

The machine has a work surface of 50 in. x 38 in. (1,270 mm x 965 mm) with X, Y, Z and W travels of 40 in. x 30 in. x 11.81 in. x 29.5 in. (1.016 mm x 300 mm x 749 mm). It can precision bore holes up to 11.8 in. (299 mm) diameter, drill holes up to 2.36 in. (60 mm) diameter and handle face mill cutting diameters up to 5.9 in.

When we got the jig borer, we said, ‘let’s try those parts on here.’ Since then, every part has come out right on spec with only one inspection at the end to confirm tolerances. It’s what happens when the tools you work with have much greater accuracies than the part accuracies you need to achieve.”

A look at the anatomy of the 6CN-II machine itself bears out Rheaume’s accuracy-in, accuracy-out contention. Mitsui Seiki uses a gas emulsion process for controlling material composition of the beds and major components, creating a thermally-stable platform for machining critical parts. Rather than simple, integral castings, the ways are made of tool steels, hardened and ground to minimize wear. Hand-scraped way mounting surfaces allow the fitting of components by hand to meet specific geometric tolerances, with less than 24 | April 2011 | www.canadianmetalworking.com

Van Zuiden’s third phase of resource optimization— and the reason for being in business in the first place—is customers.

“It is critical that we understand who the customer is and what the customer’s needs are. Many customers have quality programs designed for suppliers like us to follow. It takes a lot of hard work for a supplier to meet the quality standards they set forth. It does not matter whether we are dealing with aerospace or any other industry, people expect the highest quality from us. We like to think we’re a notch above everyone else in who we are and what we do, but the reality is we have to be that good in the eyes of our customers.”

Van Zuiden has a positive outlook for the aerospace sector and is confident manufacturers serving OEMs can compete, but they need to take the right steps to be competitive against offshore manufacturers.

“It’s a global market now and we have been weak in North America but we are fast picking up the ball. We have proven with Pratt & Whitney that we’re able to manufacture critical parts cost effectively, with respect to the Asian market. But it takes investment [in machinery] and planning and that’s what businesses need to do.” CM

GREEN MANUFACTURING

Business Report

Dollars and Sense of Green Companies are rethinking green as a competitive tool

By Tim Wilson ......................................................................................................................................................

The manufacturing sector is showing signs of rebound. And unlike in past recessions, where ecological concerns took a back seat, modern enterprises are reinventing themselves with a close eye to energy efficiency and environmental responsibility. But as with any smart business, manufacturers need to assess the cost-return benefit of going green. The good news: people get it.

“I have been involved in green manufacturing for over ten years, and I don’t have to sell it anymore,” says John Patten, director of Western Michigan University’s (WMU’s) Manufacturing Research Center. “As late as 2005 I had to explain what I meant by green manufacturing; now the awareness is there and I don’t have that stumbling block.”

The result of this increased awareness is that manufacturers are quick to engage in a value-based discussion, both with regard to brand promotion and the return on investment (ROI) that comes from green initiatives. They are also, from a purely practical perspective, responding to demand within the supply chain.

“We have to look at the suppliers as well,” says Bret Lussow, business development manager at Harrington Hoists in Manheim, PA, which has Kitco Canada as a sister company.

“Some of our large customers like General Electric need us to be RoHS compliant.”

RoHS, which stands for Restriction of Hazardous Substances, is a European Union directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment. Harrington Hoist’s Manheim plant, located 60 miles west of

Philadelphia, meets the RoHS requirements.

“Companies like GE are looking for sales opportunities in green energy,” adds Lussow. “As a result, for us to have a green focus ties in to what they are trying to do.”

The challenge is that “green” can be poorly defined – as can the costs associated with the switch to a green manufacturing philosophy. This is where third party certification can come in handy.

“RoHS functions something like an ISO standard,” says Lussow. “You want to work with other companies that can provide RoHS compliant components, and that isn’t necessarily cheaper.”

But it isn’t prohibitively expensive, either. The company’s head office, Kito Corporation in Tokyo, Japan, reports that RoHS compliance ends up costing about 0.5-1 per cent of sales. Specific to the supply chain, Kito estimates that RoHS compliant components might be1 to 1.5 per cent more expensive. However, though RoHS has a clear focus on environmentally hazardous materials such as heavy metals, it doesn’t address the energy side of the equation, which is where manufacturers can find savings.

The whole picture

“Our focus is 50 per cent environment, and 50 per cent energy,” says Patten from WMU. “We try to play both those cards in terms of opportunities in the manufacturing space.”

That blended approach covers off the main areas of environmental concern, while also allowing for a larger view from a cost www.canadianmetalworking.com | april 2011 | 25

Business Report

GREEN MANUFACTURING

perspective. If going green on the materials side costs a per cent or two, but greater savings can be found on the energy side of the equation, then management can argue for the ROI of a comprehensive approach to a truly green manufacturing strategy.

“No one size fits all,” says Patten. “Every plant we walk into for a conversion or assessment is unique. You need to have all your eyes and ears open.”

Patten is interested in addressing environmental concerns in complex manufacturing environments, providing lean assessments and waste and materials reduction—larger manufacturers in particular have issues with waste powder paints and mixed polymers. To help out, Patten can provide an economic analysis to any of the companies he works with. The results can come in either simple, immediate payback, or something longer term.

Usually the manufacturer itself will suggest a threshold.

“ The rule of thumb is for payback on energy at five years.”

“Typically they are looking at 25 to 30 per cent ROI in a two to three year payback period,” says Patten. “We put together a package that reflects a synergy between multiple solutions and projects.”

Individual examples can be presented with ROI attached, with the manufacturer targeting areas that can be packaged together and tackled as one single, larger project. Often, the combined effect reveals savings that are not evident when issues are looked at in isolation.

Going green for the long haul

The two to three year threshold mentioned by Patten represents a definite advantage that manufacturing has over many other industries: its tendency to think and plan over the medium to long term.

“Manufacturers know that investments made today will help them manage volatility in the future,” says Darin Stahl, lead research analyst at Info-Tech Research in London, ON. “They are also more directly sensitive to the cost of power and materials, and this is typically where you will see more activity from a greening perspective.”

26 | April 2011 | www.canadianmetalworking.com

But after the more obvious approaches are taken—the hoses have been checked, the recycling programs ramped up, and the HVAC systems put through an assessment and refresh—it may be time to think of a complete overhaul.

“It can make sense simply to tear the plant down,” says Patten.

“Sometimes being astute means steering people away from preconceived ideas that don’t make sense in the bigger picture.”

From a facilities perspective, the Leadership in Energy & Environmental Design (LEED) green building certification system is gaining traction in industrial environments, and becoming a de facto standard for greenfields construction.

“The LEED system looks at how the building interacts with the site, with water and energy resources, with the materials and their impact,” says Braden Kurczak, division head for green buildings at Enermodal Engineering in Kitchener, ON. “It also looks at how the building functions, such as ventilation, and from the construction side of things it addresses the systems that deal with maintenance and operational issues.”

LEED is based on what is called value engineering, which looks at a standard energy model to assess the embodied components in a building, whether steel or concrete. But when quantifying environmental practices, it’s the money that speaks.

“It is hard to express what a ton of C02 is,” says Kurczak.

“But if I say spend X dollars here, and save Y dollars there, people get it.”

When it comes to having a LEED-certified manufacturing plant, the ROI really depends on the starting point. However, the rule of thumb is for payback on energy at five years.

“Some owners will entertain only three years,” cautions Kurczak, “yet others are willing to consider timeframes that extend seven or nine years.”

For those who want to make a quick buck, or who are going green only for the marketing splash, the value and benefit will be lost, but for those manufacturers who are engaged and interested there is real opportunity. And there is a growing economy supplying to LEED requirements, just as with RoHS. “It can be hard to quantify ROI with LEED,” says Patten from WMU. “But there is a market for manufacturers to supply for LEED requirements, just as General Motors is incorporating green materials into their products.”

The argument for going green then becomes not only about the rationale for changing internal processes, but about participating in a whole new green value chain. Multinational companies like Kito, for example, are active in Canada and looking beyond RoHS to REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) certification, a strict European Union Regulation for regulating chemical substances.

“There are costs associated with this,” says Stahl from Info-Tech. “Fortunately, capital is cheap now in Canada, which means green investments can position manufacturers for ‘hockey stick’ growth.”

As the culture of green certification grows over the next decade, with Canadian manufacturers well positioned to benefit from expansion of a more environmentally responsible economy, the return on investment in going green is easier to argue than ever before.

“We will need to maintain the product performance by finding substitutes with the equivalent quality,” says Lussow, “as well as minimizing the cost rises as much as possible to avoid increasing the price of the product. But it will be worth it in the long run.” CM Tim Wilson is a freelance writer based in Peterborough, ON.

CUTTING TOOLS

TURNING

A New TURN on Multi-tasking Multi-tasking machines present unique challenges for turning tools

By Tim Wilson Getting the right cut is always important, and no less so for a turning application within a multi-tasking machining centre. Yet these machines present unique cutting tool challenges for turning.

“There has been a lot of attention given to milling in turning centres, but turning on machining centres is innovative,” says Chuck Birkle, vice president, sales and marketing for Mazak Corp., Florence, KY (Mazak Canada is based in Cambridge, ON).

Mazak has a range of machining centres, with four having particular applicability to turning: the Integrex i-150 (a high speed, small footprint multi-tasking machine); the Variaxis 630-5X II T (a five axis machine that Birkle says is “the gold standard in machining centres”); the Integrex e-Ramtec (for large cylindrical workpieces); and the Integrex 1-630V (machining harder materials).

THE RIGHT TOOL SYSTEM

The advantage of turning in a multi-tasking centre is that processes are more efficient, reducing production times. However, cutting tools designed for turning within these machines have to be compatible with the technology. Often this means working with quickchange tooling systems that aren’t fully automated. One example is Coromant Capto from Sandvik Coromant, which some studies have shown is the strongest quick change system on the market.

“Coromant Capto has a unique shape at the connection,” says Dave Andrews, product manager for threading, turning, parting, and grooving at Sandvik Coromant Canada. “It’s self-locking, a tapered polygon, with lobes that don’t allow the coupling to twist. It also has face contact on the flange, so it is a very strong connection.”

Switching from a conventional shank to the Capto quick change system means that new cutting heads can be swapped out in less than 30 seconds—a much shorter cycle interruption than would be required when changing inside the machine. Repeatability is within two microns, with the Capto “sister tool” approach keeping a machine running longer than would an insert index. This is a big help, because when 40 | APRIL 2011 | www.canadianmetalworking.com

turning in machining centres, the key to success from a tooling perspective is flexibility.

“You can adapt in different ways,” adds Randy McEachern, product specialist for toolholding and holemaking products at Sandvik Coromant. “Machines with the correct flange holder can adapt to Coromant Capto, and any one of our toolholders can go on the end of that.”

From there, extensions can make a tool longer by putting a male Capto on one end, and a female on the other to build out the assembly and also reduce the adaptor size.

“This offers total control over the length and size of the assembly,” says McEachern. “For internal machining we have an anti-vibration product that can deliver to twelve times the length to diameter on a boring bar, with Capto as the interface.”

BEYOND ISO INSERTS

For general turning applications ISO inserts function as an international standard. Iscar, which provides a full range of carbide inserts, is one company trying to look at ways of advancing tool applicability for turning in multi-axis machining centres.

“We want to look at how to enhance ISO,” says Steve

is “easily possible.” The only risk? If you increase the speeds in the machining centre too aggressively you might throw a part, and downtime in a multi-tasking machine can be expensive. “The newer machines change everything you do,” says Graham. “You have to be conscious of the set-up, because a long, slender shaft with greater depth of cut may require cutting back on spindle speed due to vibration.”

The balancing act has to allow for the fact that when turning in a machining centre the tool will have a heat band that it has to cut within. By applying the right cooling approach, higher cutting speeds are an option without compromise to tool life and chip control. In fact, it then makes low cost, unmanned production a real possibility. CM Inner diameter turning on a Mazak multi-tasking machine.

Geisel, senior product manager at Iscar in Toronto. “Our CNMX and DMNX lines are ISO inserts on steroids.”

These inserts are designed especially for machining stainless steel and high temperature alloys, with cutting force reduced due to helical cutting edges and positive rake angles.

“They can run at a much larger depth of cut and greater spindle speeds,” says Geisel. “It’s often a race between us and the machine supplier, but the end result is the best tools on the best machines.”

Kennametal’s Beyond Blast, which made its debut at IMTS 2010, delivers coolant to the point of contact of the insert.

One example is Iscar’s Heliturn LD (for “lay down”), a helical cutting edge with high metal removal rates. This is an advance in turning, but the process itself would not necessarily be any faster if integrated with a multi-axis machine.

“When it comes to turning, you will still have the same general speeds and feeds as a standard machine,” says 42 | APRIL 2011 | www.canadianmetalworking.com

Tim Wilson is a regular contributor and freelance writer based in Peterborough, ON. Geisel. “But the advantage with a multiaxis machine is the upper and lower turrets—one can be rough turning and the other can be drilling the hole and threading, even finishing behind the first turret.”

STAYING COOL

To get the most out of a turning application within a multi-tasking machine, however, the revolution may be more relevant to coolants than inserts. As cutting methods have improved, heat control has remained a major challenge.

“We have Jetstream Tooling, which I consider a revolutionary new coolant system,” says Don Graham, a manager at Seco Tools, Troy, MI. Graham says Jetstream Tooling can deliver coolant to the optimum position close to the cutting edge, thus lifting the chip away from the rake face and improving chip control and tool life.

Working within a machining centre, Jetstream can remove heat quickly from the cutting zone, and cool chips rapidly.

“We used to see 100 psi to 200 psi, but Jetstream can deliver from 300 psi to 1,000 psi,” says Graham. “The implications for this high pressure coolant on turning is very dramatic. I’ve been in this business for thirty years, and this system is the most revolutionary since the advent of coatings.”

The result is increased cutting speeds for all materials, from hard Inconels at 50 per cent faster, to aluminium at 30 per cent, which Graham says

PRODUCT REPORT Iscar

Iscar has improved its line of Cut-Grip and Heli-Grip groove-turn tools with a new CVD coated substrate that doubles tool life while raising productivity by 15 per cent, claims the company. The cutting tools perform especially well on steel, but also handle other materials effectively.

The inserts are made of Iscar’s grade IC8250, which has proven superior to the familiar grades IC9015, IC9054 and IC9025. The exclusive Sumo Tec surface treatment improves tool performance by an average of 30 per cent as it seals surface micro-cracks in the insert. This treatment reduces friction and built-up edge, improving cutting edge chipping resistance.

The new grade immediately replaces grades IC 9015, IC 9054 and IC 9025 and eventually will become the mainstay grade across the company’s entire groove-turn line. www.iscar.com

Kennametal

Kennametal has introduced the first Beyond inserts for Kennametal’s FixPerfect system, promising improved toughness and wear resistance, resulting in higher turning productivity and safety.

The FixPerfect system features a proprietary shaped pocket that, together with a clamping stud, locking pin, and tangentially mounted precision ground insert, result in high clamping forces and very low cutting forces for excellent chip control and improved process stability. The inserts are shaped to match the pocket, which protects unused cutting edges. Productivity improves as well because the pin simply needs to be loosened, not removed, to index the insert.

The inserts feature micro-polished edges that improve edge toughness, proprietary post-coat treatment that reduces depth-of-cut 44 | APRIL 2011 | www.canadianmetalworking.com

notching, and a fine-grained alumina layer that enhances coating integrity at higher cutting speeds.

“There are five new Beyond grades for FixPerfect with either two, four, or eight cutting edges, depending on your application and needs,” says Alexander Momm, global product manager, turning products.

“With a variety of geometries, lead angles, and rake angles to choose from, metalworking companies can achieve improved chip control and process stability in roughing, medium machining, or finishing tasks, while adding the long tool life and increased performance Beyond provides.” www.kennametal.com

A specially designed adjustment key with integral Bluetooth interface is also part of the system. The display unit and the adjustment key can be used for every MicroKom BluFlex precision adjustment head. This reduces costs when investing in several precision adjustment heads. Another benefit is the ability to use common batteries that can be easily changed in all components, as well as the option to use batteries in the display unit and adjustment key.

The adjustment head also offers improved performance to the integrated balance compensation. It allows greater rotational speeds that are achievable due to the separate display.

The modular Komet ABS interface makes adaptation to different machine spindles much easier. Instead of using two different connection variants (ABS or shank connection on the tool side), in the future there will only be one design with a universal tool interface that is suitable for clamping both. www.komet.com

Sandvik Coromant

Sandvik Coromant’s new ISO S insert program, which features more than 300 inserts, boosts turning of heat resistant super alloys and titanium. According to the company, the inserts come with easy-tochoose guidelines for every machining operation.

Komet

By introducing Bluetooth to the Komet MicroKom BluFlex tool system, tool developers at Komet have separated the display from the tool head making it more convenient to read off the data in a greater variety of ways. When adjusting the precision adjustment head, the user can attach the external display unit in any position within his field of view. The larger numbers and illumination of the display also make it easier to read off the settings.

Used for turning HRSA and titanium alloys for roughing to finishing through continuous to interrupted cuts, these new geometries ensure easy optimization, improved productivity, first rate process security and surface quality demands.

The six different geometries are designed to handle depths of cuts from 0.2 to 10 mm with great chip control and low tool pressure. Four geometries are for moderate to small depths of cuts in light roughing

The Super FF coating (Fine and Flat) on Sumitomo’s new grades AC820P and

AC830P is not only more wear resistant than conventional coatings, it also reduces the possibility of chip adhesion due to its smoothness. Combined with newly developed carbide substrates, the AC800P series offers higher speed capabilities and a greater resistance to breakage than conventional carbide grades when machining steels and stainless steels.

The AC820P excels in general purpose machining and is available in a wide variety of chipbreakers, including the new high efficiency EGE. For interrupted applications, the AC830P is the first choice among P30 grades. Its exceptional toughness can sustain more impacts than conventional P30 grades. www.sumicarbide.com

and others) more cost effective and more reliable than ever. Customer results have yielded tool life improvements of more than 150 per cent, claims the company.

The Sky·tec program has an optimized combination of substrate, coating and geometry working together to minimize crater wear and provide excellent chip control.

The three geometries include NFT, finishing for high accuracy at high cutting speeds, available in periphery ground or as-sintered versions; NMT, medium machining with low cutting forces due to the curved cutting edge

(effectively handles unstable components and internal machining; available with assintered periphery); and NRT, for roughing featuring rigid geometry for high metal removal rates, as sintered periphery.

The inserts are available in the C, D, S and V styles with negative edge geometry.

Two cutting tool grades are available: The uncoated grade WS10, and the PVD aluminum oxide coating (“PVD-Tiger”) WSM20. For the majority of applications, the uncoated WS10 is the first choice for machining titanium alloys.

For CNMG (80° corner angle) inserts in the NFT geometry, Walter offers a special feature: the 80° corner has the NFT finishing geometry, and the 100-degree corner has the NRT roughing geometry. Essentially the user has the added benefit of two inserts in one, thereby further reducing tooling costs. www.walter-tools.com/us

toolholding

A Firm Grip Faulty toolholding systems can wreak costly havoc on tooling and machining processes

By Mary Scianna..................................................................................................................................................

You finally find the dream machine you want for your shop and better yet, the $450,000 price tag fits your budget. There’s only one problem; you forgot to include the cost of tooling in your budget. Now you have to scramble to find a low cost tooling package while your spanking new machine sits idle, not making money for your company.

This, say suppliers, is where many manufacturers go wrong.

“It’s important to consider a tooling budget right from the start when you’re purchasing a new machine,” says Randy McEachern, product and application specialist, hole making and tooling systems for Sandvik Coromant Canada Inc., Mississuaga, ON. “In fact, Sandvik thinks this is so important that we have a group that focuses on toolholding and tooling packages for customers to ensure the right types of systems for the application.”

Unfortunately, many people regard toolholders as commodity products, adds Mike Smith, toolholding product manager for Seco Tools, Troy, MI. “You have to have a high quality tooling package and it’s often an overlooked piece of the equation of machining. Low quality tooling will create run-out, wear down or tool breakage.”

Indeed, Emuge Corp.’s David Ridenour, toolholding expert, sales, OEM manager at Emuge Corp., West Boylston, MA, says using the wrong type of toolholder can create “excessive tap breakage, threads that don’t gauge properly (oversized), torn and ragged finishes, bad thread flanks on the cutting profile, and reduced tool life caused by the one-sided flank abrasion on the threading tool which will lead to material build-up.”

Know your application needs

Knowing what you need seems like an obvious point to make, but industry experts say shops often don’t understand that different machining operations require different tooling packages.

“The insert you’re using for your machining process will determine the type of toolholder you’re going to use,” says Steve Geisel, senior product manager, Iscar Tools, Oakville, ON. “If you’re finishing, it’s a light cut with tight tolerances so your toolholder has to be able to handle this. There’s nothing worse than taking a finishing insert designed for that purpose and putting it into a toolholder that is loose and worn out as you won’t be able to hold the tolerance. For finishing, you want a toolholder that is perfectly round so it fits the insert properly and you want high tolerance inside the toolholder pocket. The better the tolerance on the toolholder, the better the repeabability you’re going to get on insert indexes.”

You should also consider the flexibility of your toolholding system, says Scott Leitch, sales manager, Exsys Tool Inc., San Antonio, FL. “By flexible, I mean a system with different types of attachments that could fit inside the toolholder and the 48 | April 2011 | www.canadianmetalworking.com

standard collet. If a collet is slipping inside the collet pocket while it’s going into the material, it means you need a much more rigid set-up, otherwise the collet will damage the cutting tool and the toolholder. It would be useful to have an adapter or an accessory to the toolholder that would create more rigidity.”

Iscar’s TorqueBeam is used for clamping screws to the correct torque.

A light indicator lets the operator know when he has reached the maximum required torque.

Using the wrong toolholders can lead to a host of costly problems, including tooling (holders and inserts) breakage, and incorrect part tolerances leading to part rejects and lost productivity.

“You have to be aware of the application. If you have an ER collet chuck with a drill, for example, and you’re running that ER collet chuck at 15,000 rpm, the collet will expand and create run-out. In this case, you may want to consider a hydraulic or shrinkfit holder,” advises Seco’s Mike Smith.

In milling applications, “one of the most common problems we see is machine shops using collet type holders for milling and thread milling,” adds Emuge’s David Ridenour. “With side thrust [forces] you really do not want to use an ER collect type holder. Milling and thread milling require something more rigid, like a solid endmill holder, shrinkfit holder or a PowRgrip system.”

David McHenry, product engineer with Rego-Fix, Indianapolis, IN, adds that different toolholding systems are designed for specific applications and “you have to find a system that allows you to get the most of your application needs. It can be extreme rigidity and no forgiveness, or a system with rigidity and some forgiveness and very high clamping forces or a design that can’t be pushed as hard and is forgiving. There are different paths that you can take to

get the tooling system that is going to best fit your machine shop’s needs.”

The right toolholder for the right application is not the only concern; Sandvik Coromant’s Randy McEachern says “you also have to consider the metal properties and the finish that you required to machine.

“Are you machining bar stock, castings, carbon steel, heat resistant super alloys like titanium? If you’re cutting certain materials, lighter tools will work, but with tougher materials, you’ll need a stronger spindle, stronger toolholder and stronger cutting unit.”

Torque: Finding the balance

The single most important piece of advice suppliers concur on is: don’t over torque or under torque retention knobs or screws on toolholding systems.

Indeed, over tightening screws and retention knobs has become such a problem that ASME has established torque specifications for standard toolholders such as CAT systems.

“The biggest thing I see is that shops either drastically over tighten the screws or they completely under tighten them,” says Iscar’s Steve Geisel. “We list the pounds per square foot recommendation for tightening all of our screws and we hope people read this and understand that sometimes an insert doesn’t have to be as tight as you can make it because that can cause problems; you can’t get the screw out because it’s too tight so you may have to break the insert to get that screw out or if you don’t tighten it enough the insert may bounce inside the pocket and you won’t be able to hold size or finish on your workpiece. The insert will vibrate and the screw can unravel itself.”

Sandvik Coromant’s Randy McEachern adds with basic CAT V or ISO taper holders contact is made at the top and bottom of the taper and “they’re supposed to make taper contact all the way and have a taper lock but no taper is that perfect. Customers tend to over torque the retention knob on the back and if they over torque it, it bulges at the bottom end of the taper and now there’s no contact between the top and bottom of the taper and you don’t have a good solid taper lock. This in turn invites vibration into the toolholder and your tools vibrate and the tool always get blamed first but in this case it’s the over torquing of the retention knob.”

While over tightening can be a problem, suppliers have responded in recent years with torque sensitive screwdrivers that indicate when you’ve reached the right tension. A word of advice for manufacturers though: “you use these torque sensitive screwdrivers to tighten the insert only; you don’t use them to remove the insert. Instead you should use a regular screwdriver to take the insert out. The only time you need to be careful is when you’re tightening the knob so you need a high precision tool,” says Iscar’s Steve Geisel.

A debris-free environment

Manufacturers underestimate the importance of shop maintenance and often don’t recognize how poor maintenance can lead to machining process breakdowns.

“Always keep bore, taper, spindle and shanks clean,” advises Tom Hagan, 50 | April 2011 | www.canadianmetalworking.com

TOOLHOLDING

milling product manager, Iscar Tools, Oakville, ON. “Dirt, debris, surface damage such as rust, corrosion, nicks and gouges cause runout and result in costly tool breakages.”

Many manufacturers rough-handle toolholders not realizing how they can quickly become damaged, adds Keith Wiggins, global tooling systems team leader Widia-Erickson toolholders, Latrobe, PA. “As a tooling supplier, we always treat our tools like jewels and have proper receptacles to keep them in. Most manufacturers are good with their tools when they first use them and then they throw them into a drawer and tooling gets scratched.

Top: Exsys Tool’s Preci-Flex Then they don’t understand why toolholder. Below is they’re not getting full accuracy Sandvik Coromant’s Capto toolholders. from their tooling systems.”

RIGIDITY IN HIGH SPEED MACHINING: WHAT WORKS BEST

Nowhere is rigidity more critical than in high speed machining applications. Whether it’s milling, turning, boring or drilling, toolholders play an especially important role in these applications.

“Rigidity in milling is critical,” says Emuge’s David Ridenour, “to eliminate chatter and harmonics and to obtain good tool life.”

CUTTING TOOLS

“If you were to take all three products—HSK, Capto and KM—and look at a cross-section, you would see that the Coromant Capto has the strongest coupling and the strongest interface in a polygon shape; there is full contact in the polygon, shoulder and then we have a taper lock. Other clamping units work on a key-way. There is a key on the face of the spindle and a key on the holder and there’s a little bit of play between the key and key way and this creates what I call a click clack effect, which invites vibrations into the tool.”

Widia’s KN toolholder line also offers three points of contact at the bottom and top of the taper and at the face. “These are full surface contacts, not point contacts. With HSK and BIG Plus systems, you only get contact at the top of the taper and at the face,” explains Widia’s Keith Wiggins.

On the other side of the toolholder equation is the holding mechanisms that actually hold inserts in the toolholder pocket—collets, chucks and clamps.

Rigidity is important and press-in collets such as Rego-Fix’s PowRgrip, the generic Shrinkfit, Sandvik Cormant’s Hydro-Grip HD and Iscar’s R-clamp work well in high speed applications. And while rigidity is key, “you don’t want to have a system that is too rigid; you need to have some forgiveness or the vibration from the cut will vibrate back into your spindle and into your workpiece, making it more difficult to machine a part,” explains RegoFix’s David McHenry.

And the need for rigidity calls for more complex toolholding systems, adds Iscar’s Steve Geisel.

“We make simple systems to complex systems depending on the operator’s level of experience, but with the more complex systems, there’s the potential of more going wrong with them. When you get into high end roughing, heavy duty metal removal and high cutting forces, you have to have a very secure clamping tool. If not, the tool pressures and cutting forces have a greater possibility of moving the insert around inside the pock, so in this case you need a rigid clamping system. We have a system called R-Clamp and it’s the most rigid way of holding the insert inside the toolholder, but we’re not the only supplier that makes this; everyone makes these types of more complex tooling.” CM

“Best types of toolholders for high speed and heavy

machining applicatins are dual contact ISO standard systems such as Capto, KM, BIG Plus and HSK.”

Experts concur that the best types of toolholders for high speed and heavy machining applications are typically dual contact ISO standard systems such as Capto (originally a Sandvik Coromant product), KM (originally a Kennametal product), BIG Plus (originally a BIG Kaiser product), HSK and other company branded variations.

“These toolholders are designed to have dual contact, meaning they have contact along the taper and along the face,” says Rego-Fix’s David McHenry, (the company has its BIG Plus version toolholder which it calls Rego-Plus). “So now you have a stopping point when the tool is pulled back into the spindle and this secures the toolholder. Manufacturers are making robust spindles for machine tools so they can take a lot of load and it’s up to us to make sure we can hold the tools properly and dual contact toolholders definitely do that.”

Not all so-called dual contact toolholders are created equal though, according to industry experts.

Sandvik Coromant Canada’s Randy McEachern says the Coromant Capto has the strongest coupling when compared to HSK and KM systems.

toolholding

PRODUCT REPORT Emuge

Emuge Corp. offers a tool clamping system known as the PGR for carbide and HSS cutting tools, taps, thread mills, and endmills.

It achieves the higher mechanical grip and torque transmission required by high speed cutting and high performance cutting applications while achieving the precision and surface quality demanded by customers.

The PGR System solves the problem of clamping shortcomings and runout inconsistencies associated with conventional colletbased toolholders. Hydraulic expansion chucks, while stronger than collets, still have grip

limitations when used in high performance cutting applications.

Compared to shrinkfit toolholders that require heat and cooling cycles to set their grip, the PGR System requires no operator heat shielding or waiting time after setting the desired mechanical grip. Unlike shrinkfit holders, the PGR System generates no heat, a safety issue requiring cooling time and caution when handling shrinkfit tooling.

The tooling system consists of a benchtop press with a quickchange adaptor with a special tapered collet and toolholder.

The cyclindrical cutting tool shank is inserted into the collet and placed in the tool holder.

The holder is designed with a gap between the collet shoulder and the toolholder that creates an interference fit. The benchtop press generates six tons of force to push the collet through the

1 | April 2011 | www.canadianmetalworking.com 52SGS_609_GIE_R2.indd

interference gap, making the toolholder expand slightly and allowing the material’s elasticity to clamp back on the tool.

Assembly requires ten seconds or less. Total indicated runout measured at four times the tool diameter from its tip, is 0.00012 in. or 3 microns.

Since the process generates no heat, the adapter requires no cooling period and is ready for immediate use. www.emuge.com

Exsys Tool

Exsys-Eppinger Preci-Flex tooling system is a unique product that uses a single base holder for collect and multiple other tooling adapters.

The modular system offers precision—a conical and flat face planar interface ensures high accuracy and rigidity—and flexibility—collets, endmill

holders, expanding collet chucks and shrinkfit tooling can all be mounted on a single base holder.

The short design ensures maximum torque transmission and rigidity, which results in increased machining accuracy and improved productivity.

The full Eppinger range of products feature different ratios for ideal cutting conditions. All wear parts are case-hardened and tools are available with internal coolant supply.

The latest addition to the Hydro-Grip product family brings secure tooling performance to the heavy roughing area.

Hydro-Grip Heavy Duty, with unique dampening features offers the high level of power and stability of a hydraulic power chuck. This ensures a good torque transmission to improve the performance of solid carbide end mills, drills and reaming tools.

Rego-Fix

Rego-Fix describes its powRgrip toolholder as a precise and cost effective press fit system for high speed, high performance cutting applications.

It achieves “superior” runout using a toolholder, versatile collect and a compact benchtop hydraulic clamping unit. The collet’s built-in set screw provides precise setting, repeatable to less than 0.0004 in. (10 microns). Its slightly tapered shape, combined with the nine-ton tabletop clamping unit, delivers high clamping force without dangerous heat or hazardous EMF radiation. It has a 10 second clamping cycle and a tool ready for immediate use without the need for cool-down, allowing for complete tool changes in less than 30 seconds.

The collet on the toolholder clamps all types of tool shanks and materials up to 1 in. in diameter in h6 tolerance.

Metallically sealed for coolantthrough capability up to 2000

It securely clamps cylindrical shank tools with a symmetrical force to minimize tool run out and ensure high torque transmission. This performance is repeated over multiple clamping cycles to retain high quality component surfaces and extend tool life, while each chuck is individually balanced to 2.5 G, for high speed capability.

Quick and easy tool set-up, and tool changing, helps to shorten planned machine stoppages. The toolholder is based on a hydraulic tool clamping system, which can be tightened and released quickly with a torque wrench, with tightening to the correct level.

The Hydro-Grip family of high precision toolholders offers secure tool clamping for many applications, from finishing to heavy roughing between 6-32 mm bore diameters. They work to tolerances within microns to improve tool accuracy, component surface and enhance the machining experience. www.sandvik.coromant.com/ca

CMMs

Quality

What you Need to Know Canadian Metalworking’s CMM expert and Metrology Matters blogger Bill Reilly provides insight on CMMs

By Bill Reilly What are the key factors to consider when choosing a CMM?

This is a big question. First, CMMs are very versatile, but you need to be clear about what the CMM’s function will be.

For instance, will it be in a lab inspecting first-off parts or on the shop floor checking production parts 24/7? Will it be checking simple parts or parts with complex geometry? Will it be checking precision machined parts or castings or plastic moulded parts, etc. What are the tightest tolerances you’ll need to inspect and what types of tolerances (i.e. form, position and orientation)? Will the speed of the inspection or cycle time be an important factor? The difference between CMMs has a lot to do with the materials used rather than the basic design, which doesn’t seem to have changed drastically in decades. Modern CMMs are built with lighter materials and smaller, more powerful servo motors allowing them to accelerate to scary speeds (hint: never lean over the bed of your CMM while a program is running to have a closer look at the part. You could end up the victim of a 500mm/sec CMM head-butt, or worse, impaled by the styli.). I’ve personally experienced the head-butt, although not at 500mm/sec, but the styli impaling was a story told by a CMM calibration technician I know.

Materials such as aluminum and ceramic are used to lessen the thermal effect but for different reasons. Ceramic has a very low coefficient of expansion and is therefore very stable throughout temperature fluctuations. Aluminum, while having a much larger coefficient of thermal expansion, reacts to temperature changes rapidly and in a linear manner and therefore can be compensated for accurately and in real time. Having said all that, it still seems the biggest advancements in technology have been made in the area of probing systems and software.

Q

and is one of the most important factors to consider.

A fixed head means you’ll be relying strictly on the probe build-up (you may need to get creative here) to reach the features to be measured whereas an articulating head gives you the flexibility of hundreds or thousands of probe positions, allowing you to reach many different features with a single probe. There are articulating heads that lock every 7.5° and 2.5° and more recently, a head with infinite possibilities. Another key factor to consider is whether to get a manual indexing head or a motorized head. If you’re only measuring 2D parts and a simple “down” probe is all you’ll need, then of course the motorized head may not be necessary, but if you’re measuring more complex 3D geometry, then I would absolutely go for a motorized head. Having a motorized head on a CNC or DCC machine allows you the freedom to run parts completely un-manned.

Take the same CMM and stick a manual indexing head on it, now

&

As far as probing systems go, there are many to choose from so I’ll just touch on the main categories. There are two distinct methods, single point probing systems and scanning systems.

Single point probing systems take individual “hits” on a given surface whereas scanning systems stay in contact with the surface being measured, gathering hundreds or thousands of points in single sweep. The big difference is point density and how much of the surface you can sample. Behind the probing system is the probe head, which can be fixed or articulating,

you’ll need to do some babysitting when running programs that have more than one probe position involved.

Equally as important as the probing system, is the software you choose. Off the top of my head, I can think of at least a dozen different CMM software packages on the market but it seems the lion’s share of the market consists of the big three OEM’s; Browne & Sharpe (Hexagon), Mitutoyo and Zeiss.

I like each software package for different reasons and wouldn’t dare pick a favourite (at least not here).

These days you can mix and match CMM manufacturers and software. For instance, my Mitutoyo CMM also runs with PCDMIS and could potentially run with Calypso if I so desired.

My advice would be to take a couple of sample parts, typical of what you will want to inspect, and have each potential OEM create a short sample program in your presence, so you can witness how user friendly it is. Take a few features you consider to be your biggest inspection challenges and compare how each software package is able to handle them. While all packages do the simple stuff very well, each has their own special features the others may not have and could make all the difference for your application. This should help you conclude which software is the best fit for your application.

In the end it’s the combination of the machine, the probing system and the software that you’ll base your decision on but it’s a good idea to look at each factor individually as well.

hard collision; they do happen and it’s imperative to know whether it has a negative impact on the accuracy of the CMM. A periodic check can be as simple as running a program on a retained sample part or test block through a program or as involved as something like the Renishaw MCG (Machine Checking Gauge), which checks the volumetric accuracy of the CMM and is sometimes part of the annual calibration process. It’s best to run your periodic check directly following the annual calibration so you can establish a baseline from which you’ll compare the results from subsequent checks.

You could make the argument that running periodic checks

Where is the best place to install your CMM?

In an ideal scenario, your CMM belongs in a separate room that is temperature controlled, free of dust (as much as possible), with a clean and dry compressed air supply, and as far away from the chips, coolant and vibrations of a typical manufacturing floor. Not all scenarios are ideal, which is why CMM manufacturers have answered some of these challenges with such features as real-time temperature compensation and air cushion vibration damping systems, which are extremely important in these less than ideal scenarios. Some pretty rugged shop floor CMM’s exist on the market with completely enclosed air bearings and guideways that can handle the dirt and dust of a manufacturing environment that would ruin a traditional CMM in no time. Some shop floor CMM’s have even done away with air bearings altogether.

In either case, there’s nothing to prevent dirt and oil from collecting on the styli so it’s good practice to regularly clean the styli to ensure reliable measurements.

There’s also a breed of ultra high accuracy CMMs which call for a clean-room type of environment to produce the sub-micron accuracies but these are the exception and not nearly as common.

The value leader just got more productive.

The new CONTURA G2 navigator combines our popular CMM with the superb mechanical properties of the VAST XT Gold sensor and the navigator scanning engine to give it even better throughput and accuracy.

would allow you to extend your CMM’s calibration frequency but there’s more to consider than just maintaining accuracy. In addition to calibrating your CMM, your calibration technician normally performs routine cleaning and preventive maintenance and believe me, I’ve seen CMMs that look like they are cleaned once a year at best, and that’s probably done by the CMM calibration technician. Given the extreme accuracy of modern CMMs and the tight tolerances we rely on them to inspect, choosing to extend your calibration cycle to save money, in my opinion, is a risky proposition.

What key advancements in CMM technology do you expect to see in the next 5 years?

Alright, so don’t get me wrong, I love CMMs and I don’t expect they’ll ever be obsolete, but there have been some extraordinary advancements in technologies such as laser scanning, white light scanning, camera systems and computed tomography (CT).

FABRICATING

PUNCHING

Punching Forces Servo electric drives are being hailed as better alternatives to hydraulics, but are they as good as proponents say?

By Mary Scianna ...................................................................................................................

Energy efficient technologies are not new to the fabricating industry. Servo electric drives in punching machines date back more than a decade. What is new is the big push by industry proponents.

“We see a trend worldwide towards servo electric,” says Lutz Ehrlich, punching and automation product manager for Prima Finn-Power North America Inc., Schaumburg, IL. “One reason is that the cost of electricity isn’t going down and therefore the economics for the servo electric side becomes very attractive, especially in those countries where businesses pay a premium for electricity.”

Prima Finn-Power is one of the early adopters of servo electric drives in punching machines, and developed its first servo electric machine in 1998.

Recent developments in energy conserving technology have reduced the electrical power consumption in LVD Strippit’s hydraulic press drive systems.

Another big adopter of servo electrics is Amada America Inc., Buena Park, CA. (Amada Canada has a head office in Granby, QC, and another facility in Mississauga, ON). In 2004, the company stopped producing its hydraulically driven punching machines and switched to servo electric drives.

“Two fundamental things drove our transition to servo ram drives,” says David Stone, product manager for turret punch presses, stamping and general fabrication for Amada America.

“Even back then we could see the hand writing on the wall for electrical costs and the cost of maintaining hydraulic systems.”

According to Stone, routine maintenance on a hydraulic system typically occurs at 2000 hours. At that point you need to replace and dispose 50 gallons of old oil. “Over a conservative ten-year machine life, you’ll spend $25,000 to $35,000 just on routine maintenance.”

Secondly, hydraulic punching machines have more components than a servo electrically driven unit.

“Our old Vipros series of hydraulic machines have almost 500 components—an oil tank, a pump, valves, hoses, fittings, chillers to cool down hydraulic fluids and many other parts—all of which are shifting, sometimes thousands of times per minute, and with all the seals and packings in these systems there are hundreds of different points of failures,” explains Stone.

Compare that to a servo electrically driven machine that, in Amada’s case, has 64 components, and it’s easy to understand Stone’s rationale about lower maintenance costs on these newer energy efficient punching machines.

Is the hydraulic punching machine then a thing of the past? Not so say some industry experts. Indeed, even some proponents of servo electric machines say hydraulic systems are here to stay, at least for now.

“The servo hydraulic side will continue until we as manufacturers [of fabricating equipment] find a way to produce the newer technology more economically because right now you’re paying a premium for this technology because it is more complex.”

Some industry experts go further and say hydraulics are here to stay not because they’re more economical, but because they offer performance benefits over servo electric models.

“Hydraulic technology has, and always will, serve diverse and demanding industrial applications,” says John Quigley, vice president of marketing for LVD Strippit, Akron, NY. “Recent developments in energy conserving technology have reduced the electrical power consumption in our hydraulic press drive systems. LVD Strippit hydraulic press drive designs offer the best balance of energy consumption, durability and productivity when compared with other press drive systems, such as electric ram designs.”

Can hydraulic systems be energy efficient? Yes, says TRUMPF, which produces “energy efficient hydraulic” machines as well as servo electric machines (launched two years ago).

“The reason we call our hydraulic system ‘energy efficient’ is that we do not use an external chiller to cool down our hydraulic fluid,” explains Mike Kroll, product manager for TRUMPF’s TruPunch and TruMatic machines, based in Farmington, CT. “We use the power of our own machine to cool the hydraulic fluid, so you don’t need the external chiller and we don’t use a lot of energy. Average energy consumption for our typical hydraulic system is about 17 kW of energy per hour.”

How TRUMPF uses the power of its own machine to cool the hydraulic fluid is attributed to its two-circuit system and single head punching technology.

“We engage only one tool in the head at any given time rather than having a turret system machine where you have all your tools in a machine at once; it’s more of a machining style concept www.canadianmetalworking.com | APRIL 2011 | 59

punching

and by doing this, we’re able to contain the hydraulics.”

Modern hydraulic press drives, adds LVD Strippit’s Quigley, are indeed energy efficient.

“We have an installed power of 11 kW and an average power consumption of 6.9 kW, [by comparison, TRUMPF’s servo electric punching machines consume approximately 6 kW of energy per hour] which is slightly higher than the electromechanical press drive. Hydraulic press drives of previous generations had an installed power of 2 kW and consumed 13 kW. Our new VX-Series feature a new technology called Energy Reduction System (ERS) developed to reduce the consumption of energy during periods of low hydraulic pressure or drops in machine activity, and to optimize and minimize power consumption.”

Hydraulic press drives are also more flexible, says Quigley. Electro mechanical press drives are “better applied to lighter tonnage applications due to the effect of shock from the punching process.

Shock has a negative effect on the components [ball screws, encoders and servo motors] of mechanical systems. Hydraulic press drives can span the array of applications from light to heavy punching as they have no mechanical linkages or ball screws that can be impacted by shock.”

Another plus on the hydraulic side according to Quigley is the controlled force this technology offers throughout the entire stroke of the ram. “Electro mechanical systems provide full tonnage only at a certain position above die height and therefore

do not have consistent and full tonnage throughout the full stroke of the ram.”

Accuracy and Speed

When new technologies get launched they’re designed to overcome issues existing in old technologies. In punching machines, proponents of servo electric drives say not only do these machines reduce energy consumption, they also perform better.

“The primary reason for development [of servo electric drives] was [reduced] energy consumption,” says Prima FinnPower’s Lutz Ehrlich. “What we have learned since then is this

punching mechanism, which is now a CNC axis, allows you to control the speed and positioning precisely, so you have better control of the punching process.”

Amada’s David Stone concurs. When his company made the switch to direct drive servo electric motors, “we increased the speed of the machine and increased the accuracy of it because we’re now using direct drive servos that use encoders to communicate with the machine control the exact position of the ram.”

Amada says its machines have higher accuracy due in part to direct drive servo motors.

LVD Strippit’s John Quigley has a different opinion. While he concedes that press drive designs of hydraulic and servo electric drives are different and therefore affect performance differently, it is the hydraulic press drives that offer the higher precision and speed in the movement and control of the punch press and ram.

“A hydraulic press drive in a typical four mm stroke length can produce all movement necessary to punch a hole within 30 milliseconds. In an electro mechanical design, the servo motor must be accelerated and then decelerated. Because of the necessity

of controlling this inertia, the fastest time it can produce for the same stroke length is 50 milliseconds. Consequently, hydraulic press drive machines offer high productivity rates.”

Ultimately, fabricators need to assess which technology best fits their application because both offer advantages and disadvantages. With hydraulics you have a long-standing, field-proven technology, which suppliers have built upon and improved. With servo electric technology, you have a relatively new technology that still has room to grow and improve.

One of the challenges is kinetics, says Prima Finn-Power’s Lutz Ehrlich.

“There is always a challenge between mechanical transfer and in this case, a force to punch a hole in a sheet of metal; there is always room to do better.”

“We’re just starting with electric technology and introduced an electric version, a 20 ton TruPunch 3000 last year at FABTECH. Our 4 ft by 8 ft (1.2 m by 2.4 m) model came out in February and a larger 5 ft by 8 ft ( 1.5 m x 2.4 m) version will be introduced later in the year.”

For Amada, the focus is now on achieving high throughput with its servo electric machines.

“We achieved as fast a ram speed as we can get so we’ve been working to improve throughput with automation and cycle times or loading and unloading parts. We’re improving the ability to finish parts out of a sheet and stack them on a pallet and not have an operator present to do so,” says Amada’s David Stone.

No doubt proponents of both drive technologies will continue to voice the benefits of their respective machining solutions. One common thread among them is the recognition of the evolving nature of technology and the responsibility suppliers have to continually improve it.

According to Amada America’s David Stone, turret punch press and stamping product manager, “the EM-series turrets have raised the bar for measuring turret punch press productivity.”

The machines perform functions that would normally have to be done as a secondary operation, such as high speed contouring with close-to-laser edge quality, burr-free slotting, high speed marking at up to 1,800 hpm, and complex forming that may normally have to be done in a press brake.

The press is designed for the high production of short-run sheet metal parts, particularly those that incorporate forming or require many holes. As far as hole punching is concerned, the EM-series is capable of delivering 500 HPM on 1 in. centres, the world’s highest hit rate, claims the company. The machines are available in 22 and 33-ton versions. Large sheet capacity of either 50 in. x 100 in. (1,270 mm x 2,540 mm) or 60 in. x 100 in. (1,524 mm x 2.540 mm) (depending on model) allows the use of full size sheets up to 10 gauge thickness without repositioning. The 22-ton machine is available with either a 45 station turret with four auto-

TRUMPF

TRUMPF’s new 3000 is available in a 4 ft x 8 ft ( 1.2 m x 2.4 m) format and offers a novel skeleton-free punching technology.

Its electric punching head technology averages electrical consumption of about 5 kW, which makes the machine energy efficient.

With skeleton free processing, an average of 10 per cent higher material utilization is realized as well as additional process reliability. Part sorting or tabbing are available, and the machine also features scratch-free small part sorting for parts from the parts flap or the scrap sorting unit.

“TRUMPF is the first manufacturer to offer skeleton-free processing directly on the punching machine,” says Mike Kroll, product manager of TruPunch and TruMatic machines, who adds that skeleton-free punching is possible for all types of geometric shapes.

The basis of this new development is powerful software with all the right nesting algorithms, combined with the option of rotating parts and leftover pieces with innovative tool technology. The result increases reliability in several areas. For example, parts no longer get stuck in the sheet skeleton; the operator no longer has to remove the leftover material from the machine table; and sorting is improved due to a turnout underneath the parts chute that automatically separates the finished parts from the scrap.

Because the punching head is not in continuous use in the TruPunch 3000, another innovative feature has been added to the machine: an electric punching head.

It’s not only quiet, but in contrast to the hydraulic version it uses very little power in standby mode. In punching mode, it’s also more efficient, which adds up to power consumption that’s two kilowatts less per hour than the predecessor model. And, on top of that, it is more productive. Thanks to its high rotation speed, the electric punching head is very fast when it comes to rotating tools or forming threads. www.us.trumpf.com

METALS/CEO SURVEY

Global Metals Outlook: CEO SURVEY

Metals sector optimistic about future: PricewaterhouseCooper’s annual Global CEO Survey

By Jim Forbes .......................................................................................................

Across all industries, CEOs are generally confident about the prospects for future growth. However, a summary of the metals sector from PricewaterhouseCooper’s (PwC) 14th annual Global CEO Survey, found metals CEOs are slightly more cautious about the future than their counterparts in other sectors.

The report found only 41 per cent of metals executives are very confident about generating higher revenues over the next three years, compared to 51 per cent of their peers. Reason being is that the metals sector was one of the hardest hit during the downturn. For example, prior to the crisis, steel prices hovered around US $1,200 and when the crisis hit, prices dipped to under US $500.

Although there have been positive indicators within the sector that the worst may be over, many issues are weighing on their minds.

“We’ve found metals CEOs are still focused on reigning

in expenses...95% have implemented a cost reduction initiative in the past 12 months....and 73% expect to repeat the exercise in 2011.”

We’ve found metals CEOs are still focused on reigning in expenses. In fact, 95 per cent of metals CEOs have implemented a cost reduction initiative in the past 12 months—and 73 per cent expect to repeat the exercise in 2011.

This focus on reducing costs is a departure from what we’ve seen in previous down cycles when cost cutting was typically viewed as a temporary measure until demand recovered. But, executives seem wary this time around, with the outlook for the global steel industry still uncertain.

In 2011, we expect all eyes to be on emerging markets like China, Brazil, Russia and India, which are seen as main sources of growth. The International Monetary Fund forecasts global growth at 4.2 per cent for 2011, but developed economies are growing at only half that rate. As such, 73 per cent of metals CEOs agree that emerging markets are more important to their company’s future than developed markets, compared to 59 per cent of CEOs overall.

As a result, competition is likely to be fierce. Metals 68 | APRIL 2011 | www.canadianmetalworking.com

companies will need access to raw materials and the energy to process them reliably and at a reasonable cost, which is no easy feat. This explains why 65 per cent of metals CEOs—nearly twice the overall average—told us they’re concerned that scarcity of natural resources could put the brakes on growth.

Although the global economy has improved, 89 per cent of metals CEOs are still worried about uncertain or volatile economic growth hurting their business as demand for metals generally follows GDP levels.

One of the biggest perceived threats is the exchange rate volatility with 51 per cent of metals CEOs expressing they are extremely concerned compared to just 22 per cent in the overall survey sample. Similarly, inflation and instability will likely remain key concerns throughout the year.

The good news is nearly half of all metals CEOs plan to expand their workforces this year. The bad news, however, is that the majority believe there is a lack of skilled candidates to choose from. Contributing to their worries, almost half are also concerned that competitors will snatch their best talent and many are facing difficulties attracting younger employees into traditional career paths.

Finding talent in emerging markets and moving experienced people on global deployments are high on the executive agenda.

Seventy percent of metals CEOs (versus 59 per cent overall) are making changes to their people strategies to deploy more staff on international assignments. While global deployments are a first step to address shortages as company footprints change, CEOs know they need to nurture local talent in the long run.

Building on the workforce issues above, technological advances are increasing the complexity of metals production and processing, so finding skilled talent in engineering and other areas is becoming even more vital. To address this challenge, 65 per cent of metals CEOs would like to work more closely with governments and education systems to improve skills in the talent pool. As well, nearly three-quarters of metals CEOs plan to support new government policies that promote “good growth.”

It seems as though metals CEOs don’t believe they’re out of the woods just yet. The impact of the recession is still being felt across the industry and has shaped the CEO agenda for the coming years. As CEOs shift their focus from survival to growth, we expect competition for skilled workers and the emerging markets to intensify. However, it’s also clear that metals CEOs are taking somewhat of a more cautious approach to growth while the economy recovers.

fume extraction

General Ventilation is not Enough Airborne impurities may affect workers from a distance

By Guy Arsenault ...............

Clean air in the work environment is not only a question of the employee health, safety and comfort.

Today clean air in the workshop is also an important factor for all companies to keep and develop their position in the market as a safe, efficient and highly productive organization.

Good industrial ventilation is becoming increasingly important as it can directly impact the company’s energy efficiency and the environment. In the production and manufacturing industries, the cost of heating and air conditioning can be more than a third of the company’s energy costs!

Welding should always take place in a well ventilated area to actively remove the toxic fumes and gases. General ventilation systems such as opening doors, roof fans, ceiling fans, heat exchangers ceiling hung circulators or extraction hoods over workbenches are often completely inadequate: the welder or operator cannot avoid inhaling the fumes as these always contaminate the general airflow. The welding fume travels through their breathing zone to the “extraction” point, so the workers are now considered part of the filtration system. To put it into perspective the diameter of welding fume particles can be from below 0.01 to over 0.1 μm at source. When the particles reach the welder’s breathing zone agglomeration has occurred (where by the particles form a small mass, creating fume particles in the size of 1- 2 μm). The size of the particles is important because it controls the depth to which they penetrate the respiratory system. Particles larger than 5 μm are deposited in the upper respiratory tract. Particles in the range of 0.1 - 5 μm, which includes welding fumes, penetrate and deposit the inner parts of the lungs (the alveoli).

Nor are systems like these necessarily cost effective: with general ventilation, large volume of heated / cooled air needs to be exhausted and this requires a great deal of power to operate.

70 | April 2011 | www.canadianmetalworking.com

The additional cost of running the system is added to the cost of re-heating or reconditioning the air in the plant.

A number of studies show that a well designed and efficient capture at source (CAS) system has the potential to drastically lower a plant’s total energy costs. It shows that a combination of balanced removal of fumes and ventilation with energy recycling is often so cost efficient that the investment in the new technique is paid off faster than other production solution investments in the companies.

Wherever it is a viable solution, it has been said that capture at source is the most effective and efficient method of capturing and removing welding fumes. Using this method, the risk to the welder or operator being subjected to hazardous fumes is minimized.

For instance, a capture at source system focuses the suction on the specific area where the fume is produced, capturing the fume before it can dissipate into the workshop. The localized capture of fumes requires much smaller airflow volume than would a general ventilation system. In a larger workshop with multiple work stations, the use of automatic dampers and speed control on the extraction fan allows for even greater savings in power consumption and re-heating cost.

There’s a handful of suppliers that have the knowledge, experience and the capacity to design, deliver and install an optimal, efficient and cost effective solution for a clean and safe work environment.

Here are some factors a pollution control expert will take into consideration when determining the right solution: • Define your welding process (MIG, TIG, plasma cutting). This will indicate the fume extraction capacity for each workstation; in some cases you will find a particular welding process that will generate more fumes than others.

• Is filtration required? A suitable filtration system will be needed if you choose to recirclulate the clean filtered air back into the workplace. Some jurisdiction will mandate a filtration system even if you exhaust the fumes outdoor.

THERE’S A LOT OF CHOICES OUT THERE.

fume extraction

• What will be the load on the filter? The airflow is not the only factor in sizing an adequate filtration system. Some processes generate a thicker and denser smoke requiring a larger filter surface area. You may calculate the same airflow requirements for two different processes but one of the two could require 50 to 100 per cent more filtration surface area.

• Is recirculation permitted? Some jurisdictions do not allow recirculation back into the workshop. When recirculation is allowed, the client may want to consider redundancy in the filtration system with the use of a “safety filter” that will stop the fume if the main filter were to fail.

• Determine the size of the operation, i.e. how many work stations, how many will be operating at the same time on average (duty cycle). Even though a welding shop may have 25 welding stations, it may not be necessary to fully size the extraction system for 25 work stations all operating at one time.

In discussion with the client, it could be determined that no more than 60 per cent of the work station will ever be working CONFERENCE at the same time, therefore allowing cost savings in sizing a smaller system. Furthermore, even if all work stations are operating at the same time, the welders are not all striking an arc at the same time in unison. The use of automatic dampers

with fan speed controls allows for suction to happen where needed when needed, resulting once again in the possibility to size a smaller system and exhausting less heated air outside. Taking this in consideration, this also allows to size a smaller filtration system if applicable.

• Determine the dimensions of the work shop, what will the distance be between the exhaust fan and the furthest point in the shop? This information is important for fan sizing and ductwork design as well as installation consideration. With a greater understanding of your welding process and work environment the consultant will design a solution tailored to your group’s specific needs.

At the end of the day to survive as a lean business, it is now standard for all manufacturing groups to run a multifaceted process by thinking green, maximizing production, efficient energy usage, reducing expenses, implementing a strong health and safety agenda which will result in having happy employees, improve product quality and last of all a being known as reputable company who produces great product and takes care of their employees.

Paint handling tips Automating paint handling operations can cut costs, but is it right for your operation?

By Nate Hendley .......................................................................................

We recently ran a few questions about automating paint handling systems past a few experts. Here’s what they had to say: How do you know if your paint handling system is suitable for automation?

“If there are enough parts and these can somehow be placed on a jig or a conveyor and go through a spray booth, there is a good chance you can convert to automation,” says Hans Wolf, liquid group manager, Wagner Systems, Elgin, IL. “Generally speaking, it is time to automate when you can no longer meet production or quality requirements. An automated system can provide higher throughput and also improved quality with regards to finish, uniformity and reduced rejects. Additionally, an automated system will also provide increased transfer efficiency or improved utilization of the coating material. This will in turn reduce material usage and other related costs and improve the margin,” adds John Owed, business unit manager, transportation group, ITW Ransburg, Toledo, Ohio.

Wagner’s automatic AirCoat gun uses the company’s new AirCoat air atomization process.

Are there levels of automation and can a company gradually move to a fully automated paint handling system?

“There are different levels of automation, but investing in automation all comes down to payback time. Sometimes it is possible to gradually move from semi-automated paint handling systems to fully automated paint handling

systems,” says Wolf.

“Automation can be employed at various stages of the painting process: application, mixing, part handling, material delivery, tracking, etc ... each area can be analyzed to find where automation can be of benefit (in terms of labour cost reduction, material cost reduction through reduction in overspray, quality improvements through more consistent paint application, worker safety improvements through reduced exposure to hazardous chemicals, etc.),” says Blake Erickson, worldwide marketing manager of Graco, Minneapolis, MN. “The amount and level of automation is typically determined by production rate requirements. How many parts need to be processed in a specified time frame?

What are the [company’s] future expansion plans and opportunities? Often we see a coating operation evolve over a period of time. With regards to liquid coatings, an end user may start out with a conventional spray gun and pressure pot. As the demands increase, the user may graduate to an electrostatic gun supplied from a small pumping system. A greater leap is then made when the user moves to an automated system,” says Owed.

What’s the best way to control the cost of automation?

“Implement the automation in phases, by applying it to areas that bring greater return on investment and have www.canadianmetalworking.com | APRIL 2011 | 73

a high probability of success. Once the automation process is running well, you can look into further areas that might allow automation to be a benefit. Graco, for example, introduced the ProMix 2KS proportioning system designed to integrate into an automatic painting operation. This system mixes two component paint and can be driven by automation to control mixing, colour changes, flow rate and material reporting,” says Erickson.

An electronic proportioner, such as Graco’s ProMix 2KS, can handle solventborne, waterborne and acid catalyzed materials and is designed to boost efficiency on the finishing line.

Equipment purchases in general are sometimes the key to controlling future costs.

“Obviously, automation is capital investment. A lot of companies can amortize that over three to five years ... the big advantage is, a robot will work 24 hours a day, seven days a week and it doesn’t stop for the flu, smoke breaks or body breaks ... and you don’t pay it benefits. In today’s marketplace [managing] benefits plays a big part in keeping

your fixed costs to a minimum,” says Brad Sparkman, president of Innovative Finishing Solutions, Orangeville, ON. Simple things, such as how you set up your plant floor or finishing process, can also have an enormous bearing on cost.

“Sometimes what happens, you have the paint kitchen miles away from application area ... that is a waste of travel, waste of changing colours, waste of solvents ... all of that can be controlled if the location of the paint kitchen is properly designed,” says S.T. Rajan, vice president of Exel North America’s Canadian branch, based in Scarborough, ON. “Invest wisely and assemble a team that consists of an equipment supplier, system integrator and coating company,” adds Owed.

What are the essential components of an automated paint handling system?

“Historically, an automated system would consist of automatic electrostatic guns or rotary atomizers mounted on a long or short stroke reciprocator. Today, an automated system usually consists of

an electric painting robot. With today’s manufacturing trends, robots offer end users a very flexible system that is adaptable to coat a wide variety of part configurations. The robot can then be coupled with a fluid delivery system and applicator that will permit quick and efficient colour change,” says Owed.

While a finishing shop will need different equipment depending on what

What impact does automating the paint handling system have on the paint finishing process?

According to Sparkman, the answer is repeatability.

While “people get tired, working eight hours in a booth” and become prone to making mistakes, robots don’t. Repeatability is one of the most critical things in finishing ... robots are servo-driven, so they’re incredibly accurate on repeatability. So with that, we can maintain consistent gun to target distance, consistent tip speed ... and then the applicator quite often will have a closed loop fluid control system so the fluid delivery stream is exactly what you want and doesn’t vary and spike.

And that all results in a beautiful [and] consistent finish overall.”

Has your company released any new automatic paint handling system components recently or have anything new on the drawing boards?

DeVilbiss, part of the network of companies that makes up ITW Finishing Technologies, recently released the

Compact Automatic X spray gun.

Said gun has a quick-release mechanism that reduces change-out time to three seconds and doesn’t require any tools for detachment. This feature is designed to speed up production.

The gun also boasts a flow rate of up to 600 cc/minute.

Wagner, meanwhile, recently released the GA 4000AC automatic AirCoat gun.

The gun offers fast application speed, low overspray and high transfer efficiency. Its compact size (the gun body weighs under 500 grams, making it “the smallest and lightest automatic AirCoat gun on the market,” according to Wagner literature) is also a bonus.

For its part, Innovative Finishing Solutions has been doing “a lot of business” with the new PPH 707 bell, a robot mounted bell manufactured by Sames, a branch of Exel Industries, says Sparkman. The bell offers “incredibly high transfer efficiency” says Sparkman and can be mounted on all types of multi-axis robots.

FINISHING/POWDER GUNS

When to Automate How do you know if it’s time to automate your powder operation?

Powder coating consultant Pierre Bachand has a few pointers that may help.

By Pierre Bachand

Investing in an automatic paint system is always a question of money, but it’s also the reason a company should invest in it.

The real question is when to invest.

1. When it is necessary to increase income (business) 2. When it is necessary to keep the present level of income (business) 3. When it is necessary to stop loosing money Here are the key factors and situations you may find yourself in that will help determine if your operation requires an automatic finishing system.

1.Requirement to increase work volume There is an increased demand for the manufactured goods produced. There may come a time when the paint line simply can’t handle the volumes. You have the very best and latest powder units but you still can’t keep up with production volumes.

You can’t add another painter as there’s no more place in the booth and you can’t more parts per rack because the painter can’t keep up. And there are costs and problems associated with opening another shift.

2. Requirement to increased line density There is a lot of space between parts or not enough parts per hook/rack but because of the square footage to be covered or complexity of parts once the painter has completed the main surfaces, he doesn’t have enough time to do any reinforcing.

3. Requirement to reduce cost per unit This is another way to say ‘we have to paint more parts in the time we have.’ We may be able to increase conveyor speed but the personnel will not keep up. It may also mean that by installing an automatic system, we can do the job of two shifts in one more efficiently.

4. Demand for repeatability This is the need for better quality parts. Parts that consistently have similar coating thicknesses and optimum coverage time after time.

5. Need to improve productivity Productivity means doing it right the first time in the most efficient way. If I’m to paint a large number of parts consistently at minimum cost, an automatic system may be the 76 | april 2011 | www.canadianmetalworking.com

answer. It is easier and more economical to put in an automatic system than to hire and train additional painters.

Automation and ROI

The most important factor to consider in deciding when automation may be a good option for your finishing operation is the return on investment. The main thing to remember is that fixed costs are variable on the number of items painted, but variable costs are fixed on those items.

Here’s an example of what I mean by this: if I invest $100,000 on a automatic system (add-on to an existing booth) it may be possible to increase production by 3,000,000 sq ft per year. My cost per part is an additional $0.03 per sq ft based on a one year payback or $0.015 over two years). Presently we are painting approximately 1,000,000 sq ft with two painters at $25,000.00/yr per painter or $0.05 per sq ft, always.

Remember that paint is a variable cost but is a fixed cost per part painted.

This thinking is good for manufacturers and custom coaters.

For the manufacturer, the need to install an automatic system from scratch may become necessary because of poor quality sub contracted parts, late reception of parts (i.e. JIT problems), increasing costs, time lost in communication, parts lost, and mistakes.

There is a simple calculation you can do to determine powder cost and estimated savings if you were to convert to an automated system.

First, you would need to know the estimated quantity of paint used annually and the approximate price per kilogram.

Your coatings supplier would be able to provide this information based on the square feet of product painted per year, the number of colours, the types of coatings and whether your finisher works with a “spray-to-waste” or closed loop reclaim or recycling powder system.

To calculate the savings you could achieve with an automatic finishing system, you would estimate a reasonable profit margin (e.g. 30 per cent) of your annual cost for painting plus transport costs and any other cost that would disappear when painting in-house, so an approximate total of 40 per cent.

The calculation then goes like this: $600,000 x 40 per cent =

FINISHING/POWDER GUNS

coaters work exclusively by batch production of small to medium volume. They do a multitude of colours and finishes and frequently specialize in parts that require masking. Some may have a small conveyor system but all the painting is done manually. The smaller coater may be forced to invest for the very same reasons the manufacturer does. To go automatic for this coater is a major change and may imply a large risk factor, especially if there is not a large pool of potential high volume manufacturers that can feed him.

The other category of coater may have a batch system but already uses automatic guns with (ideally) a reclaim/recycle system for the paint when he does large volumes of one colour.

Colour change time usually dictates if it’s spray-to-waste or reclaim/recycle.

Equipment advantages in automation

One of the advantages in moving to an automated system is the powder application equipment. Equipment suppliers have made significant improvements on electrostatic powder application systems. Two key areas of improvement are amperage control and powder flow control. Developments in these areas have improved first pass transfer efficiency and repeatability.

Amperage Control

$240,00/year. What do I need to paint this quantity of material, what needs to be purchased for this amount of money, how much labour would be required, where would I set up the system? These are the questions you need to answer.

Custom Coaters

The custom coater’s vision is a little different. Some custom

Extensive lab testing and field experience has shown that 100 kV is the maximum useful voltage that can be efficiently applied consistently to powder paint particules. Above 100 kV the improvement is negligible at best, and the dependability and life of the cascade are reduced, due to the extra stress on the insulation material associated with high voltage. High voltage constantly seeks ground; any weakness in the plastic will eventually result in high voltage pinholing.

Powder equipment suppliers all offer units that control the available amperage. These units have basic settings or recipes, typically three or four are used for specified target types. These settings are somewhat similar.

Here are a few: • easy targets • difficult targets (recesses) • recoat targets • metallic powders • low or high powder flow • small targets All the units offer additional programmable settings that

thicknesses, for example. One controller can store as many as 250 recipes or more, which is significantly more than 95 per cent of all finishers with automatic system use.

The main advantages of these new control parameters include: • reduced or eliminated picture framing • better penetration of recesses • easier recoats • easier application of specialty powder such as metallics and blends • precise thickness control • overall better repeatability of results

Powder Flow Delivery

One additional area that has benefited from technological advances is the significant improvement in powder flow control and delivery at the nozzle. A couple of years ago I completed an audit at a client’s facility where the equipment manufacturer stated one per cent variation on powder flow over a specified range. After sampling and weighing all the guns’ powder delivery it was right on target; there was not more then one per cent variation over the 12 automatic guns.

A heavier flow of coolant may help prevent BUE. Cermet cutting tool materials help reduce BUE.

NOTCHING

A notch that appears on the insert, generally at the depth of cut, occurs most often where the outer surface of the part being machined is harder than the rest of the material. This is common in case-hardened parts, or parts with a scale such as forged parts. Varying the depth of cut (DOC) will help to reduce the effect of notching. This can be accomplished by cutting a taper on the first pass and then cutting a straight pass, producing a constantly changing DOC. Other solutions include changing the grade, lead angle and chip-breaker.

DEFORMATION

Deformation occurs when the insert deforms or softens from heat or pressure. The cause is normally an insert grade that is too soft. To reduce deformation: • select a harder insert grade • reduce the speed to decrease the heat • reduce pressure by using a positive cutting geometry and reducing the feed.
