(R) Shot Peening, Computer Monitored.
|Publication Date:||1 February 2013|
This specification establishes the requirements for computer monitored shot peening of part surfaces by impingement of media, including metallic, glass, or ceramic shot. Computer monitored peening is intended to provide a method of process observation, traceability, and response for all process input settings, in real time, during the entire peening process to ensure with objective evidence, the desired process outputs. Shot peening in accordance with AMS2432 meets or exceeds the requirements of AMS2430.
Related peening processes, such as tumble peening, slurry
peening, manual peening, peen forming and straightening, peening
for prevention of intergranular corrosion, and peening to produce a
surface texture, are beyond the scope of this
Shot peening is typically used to induce residual compressive stress in the surface layers of parts, and may be used to increase fatigue strength and resistance to stress-corrosion cracking. Shot peening with computer monitoring is typically used to provide control of the peening process to ensure consistent, repetitive peening coverage and intensity on parts. Computer monitored processing is typically required so that the traceability steps specified herein can be utilized by the design authority to take full credit for the benefits of shot peening in the design life.
