2011 ICSP Shot Peening Conference: Triennial Event Well Worth the Wait

by Jack McGuinn, Senior Editor

ICSP History

Creation of the ISCSP is credited to Dr. A. Niku-Lari. With support from France's Centre Technique des Industries Mécaniques (CETIM), he toured many countries enlisting support for the concept of international conferences on shot peening. An international scientific committee (ISC) was created with 13 members from seven countries) to lend support and provide authority to Dr. Niku-Lari in setting up the first international shot peening conference. The ISC in 1980 held meetings in Las Vegas and in Senlis, France prior to the inaugural event.

With CETIM as the main organizing body and Dr. Niku-Lari as conference chairman, ICSP-1 was held in Paris, September 14-17, 1981. More than seven hundred delegates attended that highly successful conference, which had seventy-nine papers accepted. Dr. Niku-Lari edited the published conference proceedings (which notes the contributions made by some eighteen sponsors). An enlarged ISC met during the conference and formally adopted a constitution, ratified its membership, appointed Dr. Niku-Lari as chairman and modified its title to the International Scientific Committee on Shot Peening (ISCSP). A feature of the constitution was that, in order to avoid conflicts of interest, the committee was to have a majority of academic members. The precedent was set of arranging the venue and organization of the next ICSP that was to be held in three years' time. Hence ICSP-2 was arranged for Chicago with the American Shot Peening Society and CETIM as organizing bodies, and with G. P. Balcar as general chairman and Stanford University Professor H. Fuchs as honorary chairman.

To catch up with today's shot peening industry and talk a bit about the conference, we talked with Jack Champaigne, editor of The Shot Peener magazine and chairman of ICSP-11.

According to Champaigne, "While there are many Internet and magazine sources for information on shot peening, The Shot Peener is the only publication dedicated to sharing information and expanding markets for the industry. Distributed in 80 countries with 6,000 readers, there probably aren't many other "niche" manufacturing processes as dedicated to training and sharing new applications, research, products and case studies as the shot peening industry." Following is our Q & A.

Gear Technology (GT): Who typically attends ISCSP?

Jack Champaigne (JC): Primarily academics in aerospace or automotive sectors involved with metal fatigue, but also industrial participants who sell or service these sectors. Usually 15-20 exhibit booths and 200-300 attendees.

GT: Do you ever co-exhibit with other shows/industries?

JC: The ISCSP (International Scientific Committee on Shot Peening) does not partner with others for their conferences.

GT: How does the "EXPO" part of the conference work?

JC: Commercial exhibit booths are provided on the periphery of the dining and break area. The exhibits are available during the conference and two 30-minute breaks per day. Booth rental includes fee for two attendants.

GT: What do you hope to accomplish at this show?

JC: This is the eleventh international conference on shot peening (ICSP-11) and it is the only venue available strictly for this industrial technology. Leading researchers from around the world will present their papers that further the understanding and knowledge of shot peening. Related mechanical surface treatments, such as deep rolling, laser peening, ultrasonic peening, combined processes and other cold work processes, inducing compressive surface residual stresses, are within the scope of the conference-especially when compared to shot peening. I serve as chairman of the International Scientific Committee on Shot Peening and organizer of the next triennial conference, ICSP-11. I was asked to host the conference in the US to increase awareness of the benefits of shot peening to US manufacturers and academics. Shot peening was essentially invented in the USA automotive industry-which led to many improvements to the war effort-especially in improving gears and other rotating aerospace components. Naturally, many foreign countries have adopted this technology and they vigorously include it in their curriculums.

GT: How would you characterize shot peening? From what I can tell, it is a very industry-mature-but absolutely essential-component of gear making. Are technological advances somewhat rare?

JC: No, technological advances are not rare at all. In fact, the advances in process control and non-destructive testing in the past decade have made possible the development of lighter, stronger components in automotive, aerospace and medical manufacturing. Fine-particle shot peening (FPSP) is used for Formula 1 race engines and by high-end luxury cars on all of their transmission gears for better lubrication which reduces friction and noise. FPSP is also used in gear manufacturing as the second treatment for duplex peening. This second treatment, after high intensity peening, puts a very shallow compressive stress in the surface and helps extend the fatigue life and increases the load capability. Remember, it's the surface where the crack initiates. Paying attention to the surface is the most critical aspect of achieving long fatigue life.

GT: Are there shot peening standards?

JC: Yes. Many aerospace companies have proprietary standards and SAE has several industrial standards. These standards are addressed in two committees: the Surface Enhancement Committee is custodian of the "J" series of standards, and the Aerospace Engineering Materials Committee (shot peening subcommittee) address the "AMS" series of standards. I happen to chair both of these committees.

GT: If gearing is black science, it would appear that shot peening is alchemy. What background does a typical player in the shot peening typically have?

JC: It depends upon the industry. Aerospace technicians are highly trained and certified to perform peening. They must attend an accredited class on shot peening and achieve a level 1, 2 or 3 rating. The machine operators, as well as their quality department and sometimes the design team, will attend these workshops or in-house sessions on shot peening. The automotive sector relies mostly upon on-the-job training. There are also training programs for FAA inspectors that must audit facilities performing shot peening. In addition, many aerospace companies adhere to Nadcap guidelines that require strict adherence to shot peening standards set by such companies as Boeing, General Electric, Pratt and Whitney etc.

GT: Is the heat treat industry a close "cousin"?

JC: Yes, a very close cousin. Shot peening often is the next step after heat treatment and it is common to see conveyor lines leading from heat treat right into the shot peening machines.

GT: Why the long wait-three years!-for technical papers' availability?

JC: This was a practice established with the first conference in 1981, which would allow the local organizing committee a generous amount of time to sell remaining copies of the proceedings. After the three year period the papers can then be downloaded for free from the official web site. This restriction may be revised at the next conference meeting in September.

GT: An admittedly cursory review of the technical paper authors seems to indicate the vast majority are Asian or European. True? If so, why is that?

JC: Asian and German car manufacturers not only adopted shot peening but they embraced it, and Detroit practiced it but did little to enhance it. It's basically a cultural difference. Some societies emphasize quality and constant improvement. Some societies continue old practices, either for lack of educational support or lack of incentive to make progressive changes. You'll see that the Koreans are approaching (or have achieved) the same quality level as the Japanese. The Chinese are getting very aggressive in their pursuit of an improved standard of living and they are eagerly adopting shot peening practices.

Again, one of the goals of hosting ICSP-11 in the USA was to expand shot peening research here and to not fall behind in the race for excellence.

11th International Conference on Shot Peening

General Information
About. The Eleventh International Conference on Shot Peening, hosted by Electronics Inc. and The Shot Peener Magazine, will be held September 12-15, 2011, in South Bend, Indiana USA.

Scope. ICSP-11 is the 11th International Conference on Shot Peening. Related mechanical surface treatments such as deep rolling, laser peening, ultrasonic peening, combined processes and other cold work processes inducing compressive surface residual stresses, are within the scope of the conference, especially when compared to shot peening. Shot peening and related mechanical surface treatments have proved to be powerful instruments in enhancing the resistance of components to various kinds of stress-induced damage, particularly with respect to fatigue and corrosion damage. The service lives of a wide variety of structural components, irrespective of shape and dimensions, can be improved dramatically by shot peening. The commercial benefits of applying mechanical surface treatments are increasingly recognized- especially in the automotive and aerospace industries.

ICSP-11 is an important international meeting for discussing the science, technology and applications of mechanical surface treatments. It provides a unique forum enabling scientists and engineers to deepen and update their knowledge of all aspects of mechanical surface treatments. ICSP-11 will cover a range of surface treatment topics based on:

The study of shot peening's benefits and uses are crucial, as the need grows for stronger and lighter metal components in transportation, medical and many other applications.
