Machining for the Stars
March Madness Swarf
By Lloyd Graff
Tattoos on NBA players irritate me. Lebron James has 17 body tattoos that have been identified. Though it is suspected that he has others which have not appeared in photos.
I see the proliferation of body hieroglyphics as a reflection of the “look at me I’m a star” braggadocio that sullies the slam dunk league. I am an old school basketball purist who revels in team play and a flawless fast-break. I love a Steve Nash or a Chris Paul because they can score and dish and improvise the game into Brubeck jazz.
I ask myself if my annoyance with tattoos is latent racism, generational divide, or just hoops snobbery. It probably has some of all three elements. Though I see a Chris Anderson as the ultimate narcissist, a mediocre white player displaying himself like a spooked peacock.
Anybody who follows my writing knows that I am a sports enthusiast. Basketball has been a love since I watched Bob Cousy make no-look behind the back passes to Bill Russell for the Boston Celtics. I think Lebron is the most talented basketball player I’ve ever watched, but watching him take over a game with one on one play in the fourth quarter is as annoying as looking at his tattoos.
Question: Do you feel that body ink is symptomatic of a thuggified cult of personality NBA or am I a hopelessly out of touch Frank Sinatra white guy in a Lil Wayne’s world?

GibbsCAM 2010 to be Demonstrated at WESTEC 2010
Includes New Plunge Roughing, Additions to 5-axis and Advanced 3D Machining, Plus 64-bit Implementation
MOORPARK, CA – March 1, 2010 – Gibbs and Associates, developer of GibbsCAM® software for maximizing programming efficiency of CNC machine tools and a Cimatron company, announced today that it will be demonstrating GibbsCAM 2010 during the WESTEC 2010 show at the Los Angeles Convention Center in Los Angeles, California from March 23-25, 2010 in booth #2236. This new release includes multiple new features, additions, enhancements, and productivity tools.
“We have been working very hard to provide customers new functionality across the GibbsCAM product family,” says Bill Gibbs, founder and president of Gibbs and Associates. “We added many capabilities to make programming and machining easier and more efficient, especially with new features in 5-axis and solids machining. We also implemented 64-bit operation to enable faster processing of long programs and complex parts, added support for new tools and tool holders, extended functionality within various modules, and extended and updated interoperability with various CAD systems,” he adds. “All this is in addition to the recent integration of VoluMillTM and making GibbsCAM compatible with the Windows® 7 operating system.”
Key GibbsCAM 5-axis Enhancements
These include more spiral machining options, new gouge check projection options, a new lead in/lead out “flip” option, a new axial shift damp option for trimming applications, and support for countersink and keyway cutters. More specific additions are the following.
Geometry Creation – A Surface Tools plug-in has been added to create surfaces for repairing or improving machinability of surfaces from solids.
Adaptive Cuts – This new option enables regulating the distance between paths based upon the angle of the surface to be machined to provide a consistent surface finish, regardless of surface angle.
Impeller Roughing – Has been enhanced with functionality that covers more contingencies, especially useful when roughing near and around splitter blades.
Tool Retraction – A new option, Retract Through Tube Center, enables retracting cutting tools from angled pockets while avoiding walls, especially useful for machining cylinder head ports and similar geometry.
Key Enhancements to Solids Machining
New, More Capable Plunge Roughing – No longer a plug-in, it is a tile in the CAM palette, with the ability to calculate material removal strategies that accommodate carbide-inserted drills, which require special motion for no-drag retractions, while avoiding collision in tight or narrow areas.
Enhancements to Advanced 3D Machining – These include the addition of Hit Flats with specified tools for Pocketing, the ability to specify flatness tolerance in Flats Cut to ensure all desired “flat” areas are machined, locking high feed rate for Shortest Route and Minimal Vertical retract styles, addition of Trim to Ramp Advance as a Contour option for waterline cuts, specifying surface finish with step-over distance or scallop height parameters, and using Stock Bounding Box as an additional machining boundary.
Addition of Option for Stock – Facet bodies, generated from a previous machining process, or brought in through a data file, can now be used as initial stock in solid pocketing.
64-bit Implementation
A significant development, the 64-bit implementation allows taking advantage of the more powerful, multi-processor PCs equipped with 4GB or more of RAM. This provides tighter interoperability with 64-bit CAD systems that are co-resident with GibbsCAM on a PC. Also, 64-bit operation reduces computation time when processing extremely long programs or working with complex geometry. It will also enable users to take advantage of system enhancements when running under the Windows 7 operating system.
Even More Enhancements
GibbsCAM 2010 includes many more features, some for ease of use, and others to extend functionality, including enhancements to the user interface and for the Milling, MTM (multi-task machining) and Wire EDM modules, as well as new add-ins for data exchange to support Inventor 2010, SolidWorks 2010, and additional CAD file import and translation. Furthermore, the Macros menu was enhanced with changes for easy access, uninterrupted operation, and support for 5-axis and Advanced 3D processes and calls to plug-ins.

Time to Develop Young Machining Talent
By Lloyd Graff
The most stunning conclusion I reached from the Precision Machined Products Association (PMPA) Management Update Conference last weekend in Phoenix is that the precision machining operations business is good right now. Whether it was the automotive contingent, the aerospace guys from the coasts, the mixed baggers, the brassers or the ammo and firearms suppliers, the PMPAers were generally happy. What a change from a year ago.
The PMPA’s statistics show the same reflection of business. Sales levels are still off peak levels but profits are solid because of significant gains in productivity. The pruning effect was referred to by almost everybody I talked to. Weak employees have been shed. Processes have been sharpened. Companies are lean and hungry.
Contrary to the idea that nobody is hiring, the folks in Phoenix were looking. What they were seeking is youth and energy. Skills are a plus but they can be developed. We are at a point in the business cycle where you can find smart eager young people who are ok with starting out on the cheap and working their way up.
Dave Knuepfer of DuPage Machined Products outside of Chicago is hiring high school kids as interns hoping one out of three will stick. Ron Bracalente of Bracalente Manufacturing in Trumbauersville, Pa., is hiring engineers out of school for $13 per hour and fast tracking them up the pay scale if they can cut it.
Precision Machining is shedding its old skin coming out of this recession. The focus in Phoenix was not about adding machine capacity, it was about acquiring young talent during one of those rare windows of opportunity.
Question: Are you using this period to acquire young talent?

From Passion to Product: Reinventing a Company Through Innovation
Today’s Machining World Archive: September 2006 Vol. 2, Issue 09

The machining community is filled with ideas about making better products. The challenge is to take the imagined product, then the tinkered prototype, and finally, the working model into the marketplace. And if the market embraces the new product, how do you take it from product to business to brand? For dreamers and contract machine shop owners, Corsa Products of Berea, Ohio, and Manth-Brownell of Kirksville, New York, are working examples of companies in the process of turning their ideas into viable market winners.
ENTREPRENEURIAL BENT
Jim Browning Sr., president of Corsa Performance, started out making exhaust components for the marine industry in his garage in 1989, after leaving his senior management job at an automotive components group. Building on his love of boats—he has built three himself—Browning went to two nearby boat manufacturers and asked what their biggest problem was. They told him it was water surging down the exhaust system into the engine. Engines at that time were equipped with valves to stop the water, but the ones on the market failed frequently, causing major headaches for boat owners and the manufacturers.
Browning set out to solve the problem, and with the help of a former NASA engineer, developed a new antisurge valve that’s now found on the majority of boats with inboard engines. Browning and his two sons started making the valves themselves, hand mixing the batches of silicone that form the water seal. His next problem was developing a new exhaust diverter valve to direct the exhaust path through the propeller for quiet operation or through the hull above the waterline for maximum performance.
A major marine engine manufacturer had a complicated pneumatically operated diverter valve that was heavy, expensive and prone to failure. Browning devised a much simpler mechanism driven by a proprietary high-power solenoid. That product was so successful the engine manufacturer dropped its product altogether.
From there, Browning developed exhaust systems that are now found in nearly 80% of boats on the market. The company grew to 115 people, selling high performance exhausts around the world to the marine and automotive markets.
Browning was satisfied making marine exhausts, until the automotive world came calling.
John Lingenfelter, a renowned builder of high-powered Corvettes, asked Browning to build an exhaust system for a new Corvette package. Of course, he needed it in two days so the car could be tested by writers for Car & Driver and Motor Trend magazines. During the tests, the car suffered from droning, a low-frequency hum that’s annoying and fatiguing for those inside the vehicle. Browning wasn’t satisfied, so he went back to his engineers for a solution.
Nine months and eight iterations later, Corsa’s patented Reflective Sound Cancellation technology was born. Browning got an early publicity boost when the exhaust was fitted to the Corvette pace car for the May 1998 Indianapolis 500. He started shipping product in June 1998.
The RSC technology uses the sound waves themselves to cancel out certain frequencies, much like waves from pebbles dropped in a pond collide and subside. Inside a car or truck equipped with a Corsa exhaust, the bothersome low-frequency noise is banished, making normal conversation possible, even in a diesel pickup truck under full acceleration. Outside, the roar and rumble that enthusiasts crave is still impressive.
The fi rst Corsa exhausts were aimed at the Corvette enthusiast market, but have since expanded to include many GM models and vehicles from other manufacturers, including Dodge, Ford and BMW.
PATENTLY PROTECTED
Browning was quick to patent his technology, even though there was little danger of anyone stealing it at the time.
“Sometimes you have an idea, and people look at it and don’t think anything of it, like our car muffler,” Browning said. “It’s taken a while for people to appreciate the value of it, but they certainly do now.”
He regrets not securing a patent on the shape of the exhaust tips, the showy chrome that lets observers know the exhaust system is something special. That shape is starting to show up on competitors’ products.
“The next time I come up with some new exhaust tips, there’s going to be as much patent protection as I can possibly get on it so we that we don’t have people stealing from us,” Browning said.
GROWTH MODE
Corsa recently adopted a new distribution model, leaving behind a relationship with General Motors and placing its products with major distributors and wholesalers for mail order, specialty shops and warehouses that reach about 46 % of the marketplace.
The company is also spending more on promotions, becoming a corporate sponsor at the Mid-Ohio Sports Car Course and increasing its marketing outreach as it adds more vehicles to the lineup.
“We’ve elected to spend money on product development instead of advertising,” Browning said. “Everybody that has a Corvette knows about Corsa, but for a Chevy pickup truck, maybe not.”
With the new distribution model fueling growth, Browning is considering building a new factory and research center because the current facility is running three shifts a day and there’s no more room. It’s not the first time Browning has been in this situation, as his previous employer went through a similar expansion. The lessons he learned there enabled him to lead Corsa into its next phase, including bringing on board qualifi ed people with experience at the auto manufacturers.
CHOPPER CHALLENGE
Management at Manth-Brownell, a $24-million manufacturer of turned parts in Western New York, is looking to bring new energy and hopefully a new line of business to the company by making custom parts for the motorcycle industry.
Wes Skinner, president of Manth-Brownell, said the idea germinated in a strategic planning session.
“We said we need to be getting into higher complexity work, and we kicked around a lot of ideas,” Skinner said. “The energy in the room began to come up when we got around to things where we’re doing our own products.”
The group considered products such as jewelry and hardware, but a shared passion for motorcycles won the day. The team decided to enter the custom chopper arena by marketing to bike builders who need a steady stream of unique, high-quality bling bling for their projects.
“We are customizing anything that you can do on a motorcycle that would be unique,” Skinner said. “Our theory is to go into something where there’s a lot more energy and excitement, and position ourselves using customization. We are looking for products that flow out of that.”
After only four months on the project, TV cameras have been in the plant twice, as the Fox Network taped segments for a biker build-off program featuring custom parts turned at Manth-Brownell.
Skinner had found that building relationships with bike builders and generating publicity may be more important than machining skills.
“It’s all based on connecting with people and getting them to like you,” he said. “There’s a whole motorcycle culture, and you have to join that culture.”
Skinner and his team set aside a budget for developing the business and hired a designer. The goal is to develop a business before the budget is exhausted. Being a part of the TV shows is a step in the right direction for the fledgling effort.
“Notoriety is what we’re looking for,” Skinner said. “This is high energy, and it’s a break from screw machining. It’s something where our people get to see the end product.”
Skinner has added a graphic designer to his staff. His traditional screw machine business of Wickmans and Davenports did not prepare him for his one-of-a-kind designs for choppers. But he and his staff are learning on the fly.
The Machining Business is Coming Alive Again

Groups like the Precision Machined Products Association (PMPA) are still dominated by old white guys who can’t jump, but it’s beginning to turn over in a few ways. One of the nice things about going to a conference like the PMPA Management Update in Phoenix last weekend is to see an organization evolving.
Owners, many second and third generation machine guys themselves, are looking to rejuvenate their businesses with young talent. I heard this from almost everybody I talked to at the conference. A lot of older shop workers have retired or been pruned. The managers of many PMPA shops are looking for fresh talent out of local engineering schools, tech schools, high schools—wherever there are kids who want to work hard and are willing to use Lava soap. You can’t advertise specifically for youth, but in America today you can shop the abundant talent pools, looking for what you want. For 30 years, the constant lament at these gatherings has been “you can’t get talent.” In Phoenix, the belief was that at this moment you can get “potential” that you can develop.
I talked to several young guys—30 is young to me now—who are running things at their shops and feeling good about it. Dave Thuro is pretty much running things now at Thuro Metal products in Long Island N.Y. The company is pushing hard on exporting to Europe and Mexico. Eli Crotzer of Hi-Vol Products, LLC, an automotive cold header turned Hydromat shop in Livonia, Mich., came into the machining world through the private equity door. He says he’s about as technical as a baked potato, but he’s learning fast, selling off one shop in his boss’s portfolio and looking to more ongoing operations.
Aaron Bagshaw of W.H. Bagshaw Co. Inc., carries on the company name after 140 years in the business. He’s adding CNC bargains to his successful line of pins. He was proud of the five Nomuras he just “stole” for $23,000.
Machining is getting a life again right now as the know-nothings write it off.
Creative destruction is alive, under the rubble.
Question: Do you feel the machining business coming back to life?
