‘Smart’ Machines Provide High Control to Fatigue Life Improvement Process

Computer-controlled shot peening is increasing the precision of this surface enhancement process, according to a recent article by Wheelabrator.  This evolution in peening equipment allows for air pressure and shot flow – the two key process elements for shot peening – to be monitored and adjusted by computer-control.  Shot peening imparts kinetic energy into a metal component through the targeted application of mass (as determined by shot flow) and velocity (as determined by air pressure), to improve the fatigue strength of the material and increase the fatigue life of the component. Improving control of these process variables through computer automation enhances the precision and repeatability of shot peening results.  See the full Wheelabrator article for more information:  Smart machines make Aerospace peening a precision art
