 Enhancing Part Life by Managing Residual Stress

The stress state remaining in a part after manufacture of that part has a dominant effect on performance.  It is well known that the life of highly stressed parts such as gears, bearings, stamping dies, cold work dies, etc., is significantly improved by the presence of compressive residual surface stress.  This presentation will discuss the major manufacturing processes used to impart this beneficial residual surface compression.  Process fundamentals and applications will be presented.

Case hardening is the most commonly used method for achieving high surface compression in cyclically loaded parts such as gears and bearings.  For dies, surface treatments, such as nitriding, may provide a similar benefit.  Typical processes include carburizing, nitriding, carbo-nitriding, and case hardening by induction heat treating.     Not only is the local surface hardness increased, but local compressive stress is imposed to enhance fatigue life of the component.

Mechanical methods are also used to ensure that part surfaces are under residual compression after all major manufacturing steps, including machining, heat treatment, and finish grinding, have been completed.  Often finish grinding, especially aggressive grinding, imparts surface tensile stress which is detrimental to part life.  These mechanical methods of providing residual compressive stress include shot peening, burnishing, surface rolling, and laser shockpeening.  This talk will compare conventional shot peening and laser shockpeening in terms of application method and the resulting stress state and benefit to part life.

From Problems To Profit

Improving your manufacturing cost problem solving skills
with guest speaker Tony Kusnerik

Chain saw chops sure sound like they cut costs, but they're more likely to kill your company than save it. Major surgery is the better model - cutting out the dead tissue and deftly suturing together the living. That means

knowing what really is alive and dead in your company, which is rarely a simple matter. Tony Kusnerik presented the methodology to become a master hand in these operations in his presentation. He discussed how to root out avoidable downtime and wasted resources by walking around your plant observing the workflow (or non-flow), digging into the economic impact of these problems and talking with workers to develop solutions.

It is actually surprising to realize that for whatever reason, manufacturers assume that engineers and managers come to their jobs with all the skills necessary to solve complex manufacturing problems for the lowest total cost. The truth is that engineers and managers do not come to their jobs with such skills for the simple reason that such skills are not taught formally. Instead, manufacturing people are left to their own devices to learn such skills and that learning comes at a high price to manufacturers as people “cut and try” to find the best solutions for sometimes very complex and costly problems.  Some fare better than others of course, but very often, such cut and try solutions are slow in coming, they are rarely optimum, often not permanent, and as a result, manufacturers find themselves solving the same or similar problems over and over again at needless cost and loss of profit.

 The problem solving training provided from this presentation
was compatible with and supports Lean and Six Sigma programs.

 “6-Pack Apps – Svelte Circuits for Complex Controls”

Well, maybe only 3-pack apps, at least as we got to see, but Valtronic USA is leading the way in “packaging” circuit boards for everything from medical implants to Formula 1 Racing. When you need to cut out weight and mass without losing functionality – and usually even improving it, Valtronic's system combines microelectronics with micromechanics to produce miniaturized circuits. These wire and RF circuits are used in such advance medical devices as neuromuscular stimulation and retinal implants; and data acquisition and control devices connected to sensors in Formula 1 race cars.

Donald Styblo, VP of Technology and Deb Marko Koeberer, Sales Specialist and University Liaison made a presentation of Valtronic’s products and systems and lead a tour of Valtronic’s manufacturing facility, where they produce:

“Nano-101; Taking the Angst out of Angstroms.,
and Making Money out of Molecules.”

 Nanotechnology is making money in the mass market today. Who would have thought, ten years ago, that someone would be diffusing materials into fabric with a thickness measured in billions of a meter that made them extremely stain resistant and be marketed today at shirts, suits and pants? They’re in the stores and on the shelf now. Who would have thought, 40 years ago that Thalidomide could reemerge as a SAFE effective sleep aid? It appears that there are two symmetric forms – one spins left and the other spins right, just like dextrose and levulose – and nano engineered twisted tubes only let the safe ones filter pass. Yet these are just two applications, with many others ongoing and reaching the threshold of market penetration. The scientific and technological basis for the industry is exploding and the winners of today's and tomorrows markets will accelerate their understanding and applications research to survive and prosper.

 SME, Chapter-220 and Auburn Career Center hosted a Nano-101 presentation by Alexis Abrahanson, PhD Mech Eng. of Nortech/Nanotech. This is designed to inform conventional industry, provide an education in the basics, and demonstrate some early applications. Two attendees in mature businesses, one a member of SME Chapter220, are working on new nano applications as part of their NanoVate program now as a result of this presentation.

Plant Tour
The Cleveland Plain Dealer
Production and Distribution Center

NE Ohio Chapter 220 visited the PD Center in Brooklyn Ohio.  The printing process was a very efficient process of material flow and lean processing.  The overturn of product is an exquisite example of lean methodology. Use of material, information transfer, and quick change setup provided our tour with much to learn from. 
 

Cleveland Chapter 3 & Northeast Ohio Chapter 220

hosted the
2007 Frank Jenkinson Memorial Golf Outing
at the

Manakiki Golf Course
 

SME members participated in the 
Ohio Solar Tour
This tour allowed guests to learn about many 
Alternative Energy Solutions that many local companies and private homes are currently using 
to help lower their energy costs.  Examples are displayed throughout the entire state.

This tour was sponsored by the 
Green Energy Ohio

This tour is the first weekend of October every year!
