Description |
| Abrasive Handling and Control | Dwight Lutsko | There is more to a shot blast machine then a cabinet and a throwing wheel. Media has to circulate from the hopper, through the wheel, into the cabinet, through a reclaim system of elevators and reclaim equipment, past the dust collector and the media size segregations screens and back to the hopper. Learn what each element does, why you need it and how to specify and maintain it. |
| Advanced Peening Intensity | Jack Champaigne | This presentation reviews the basic concepts of basic saturation curves and then offers three practice saturation curves that students will develop. How to choose the correct Almen strip exposure time for the saturation curve is discussed.. EI's free curve solver program will also be demonstrated. |
| Advanced Peening Techniques and Applications | Ken I'Anson | Learn about tools and techniques to solve difficult peening configurations with emphasis on robotic parts handling. |
| Air Blast Equipment Maintenance | Ken I'Anson | Air Blast Equipment Maintenance Learn how to operate, diagnose & maintain air blast machines for maximum operating efficiency using diagnostics and trouble shooting for air blast machines featuring the PRIMS Process Reporting and Integrated Monitoring System. |
| Blast Wheels | Dwight Lutsko | Historical developments to today's Impeller/Control Cage wheels, wear items, controlling blast patterns, load and motor amps. Innovations and The Future? |
| Ceramic Beads for Surface Treatment and Shot Peening | Jeff Girman | Learn about shot peening applications . Topics will cover rudiment aspects of ceramic beads and their chemical properties, and various surface applications, all with emphasis on shot peening. |
| Corrective Peening for Fighter Aircraft Components | Sylvain Forgues | This class will present a study on rework alternatives following the poor peening of critical fighter components. The effect of coverage, Almen intensity and surface finish on fatigue life will be discussed. Rework alternatives will then be presented including direct re-peening, polishing + re-peening as well as multiple re-peening. |
| Dust Collection | Case Ferguson & Dwight Lutsko |
What is Dust? It's size and the Physics of Air, Types of Dust Collection units, Fires and Explosions, Maintenance Tips and new NFPA and OSHA requirements. |
| Flapper Peening Lecture | Dave Barkley | This class goes over the specifics about the Flapper Peening process. Prerequisites for this class are the basic intensity and coverage classes. Workshop participants interested in being certified for Flapper Peening (FAA #AGL/1207/0005/8) will be required to take part in a hands on practical conducted after a written exam. |
| Flapper Peening Lab and Practical | Dave Barkley | Workshop participants that are taking the flapper peening exam will learn then demonstrate their ability to properly apply the process. (Each student will require 15-30 min to complete practical. Time may be extended beyond schedule to insure all students can finish) |
| Laser Peening | Jim Harrison | Laser peening can impart a compressive stress about twice as deep as conventional shot peening. This is very important in rotating jet engine parts for FOD control. Learn about the space age technology used for critical peening applications. |
| Mass Finishing | Sylvain Jette | Mass Finishing: This surface treatment processes is found in most aerospace and automotive manufacturing and is generally the next stage after shot peening. Few articles and presentations can be found on this topic so this new class will discuss the topics of equipment, abrasive selection, compounds, automation and waste water management in regards to Mass Finishing. |
| Nadcap Audit Preparation | Dr. John Cammett | This class will help you prepare your team for a Nadcap audit such as those conducted by Nadcap. including the inspection of equipment, paperwork, media, and the proficiency of the operators in the shot peen process. |
| Peening Applications | Jim Harrison | Has your exposure to shot peening been limited? Well, this process is not a one trick pony. This class shows many different applications of shot peening from stripping to strengthening to forming. |
| Peening Coverage & Masking | Jack Champaigne | Coverage, too much or too little can be detrimental. Learn how to measure and control coverage by evaluating samples of % covered. This session also discusses masking techniques to prevent coverage in peening-prohibited areas. |
| Peening Intensity Basics | Jack Champaigne | This class will introduce the concept of peening intensity and how it is measured using Almen strips, holders and gages. Almen’s patent, granted in 1944, and the SAE guidelines are reviewed. The saturation curve and the 10% rule is explained and guidelines for new set-ups and verification trials for peening intensity are discussed. |
| Peening Media Specifications | Jack Champaigne | This class examines the acceptable forms of media used in peening as well as proper media selection and maintenance. |
| Peening Overview | Dr. John Cammett | Are you fairly new to the world of shot peening? This introductory class explains the history and basic theory of peening as well as examines common reasons to peen. |
| Peening Science | Dr. John Cammett | This advanced class dives into the science of peening. This session is recommended for production engineers, supervisors and quality personnel. |
| Residual Stress Measurement | Mohammed Belassel | X-ray diffraction (XRD) is the standard tool for measuring residual stress in shot peened components. This session will explain how XRD is used to quantitatively measure residual stress, the types of equipment that are available, the basic techniques and the type of information that can be obtained to optimize the shot peening process and ensure that peening has been correctly applied. |
| Shot Peen Forming | Jim Harrison | Wing skins can be formed to have a curved surface. Like with an Almen strip, Peen forming involves blasting a stream of shot at the metal surface with each piece of shot acting as a tiny peening hammer but unlike most other forming methods, all surface stresses generated by peen forming are compressive - counter-balancing the tensile forces acting on the lower surface of the wing while the plane is in flight. |
| Specification Conformance & Equipment Design | Kumar Balan | Wheel and airblast equipment and process design to conform to commonly used specifications (GM, Ford, Pratt & Whitney) with specific importance to NADCAP audit requirements. Critical process parameters relating to quality assurance in peening applications. Technical advances in monitoring peening process variables. Developments in computerized reporting techniques. |
| Turbo-Abrasive Machining | Dr. Michael Massarsky | "”Turbo-Finish” is an automated mechanical deburring and finishing
method originally developed primarily to automate edge finishing procedures on complex rotationally
oriented and symmetrical aerospace engine components. Since its inception this method of utilizing
fluidized free abrasive materials has facilitated significant reductions in the amount of
manual intervention required to deburr large rotational components by these manufacturers.
Additionally, the process has also proved to be useful in edge and surface finishing a wide
variety of other non-rotational components by incorporating these components into fixturing systems. The advantages of this method go beyond the simple removal or attenuation of burrs. The method is also capable of producing surface conditions on these critical edge and surface areas that contribute to increased service life and functionality of parts that are severely stressed in service. Among these are: (1) the creation of isotropic edge/surface conditions. (2) the replacement of positively skewed surface profiles with negative or neutral skews and (3) the development of beneficial compressive stresses and improvement of stress equilibrium among part features. |
| Ultrasonic Peening | Sylvain Forgues | Ultrasonic Peening: How Good Vibrations Can Increase Your Life. In this class, the fundamentals of Ultrasonic Peening will be reviewed along with the types of equipment available on the market. Several production and repair applications will then be discussed to illustrate how the technique can lower costs and shorten cycle times while providing an excellent fatigue life improvement. |
