An Overview on Influence of Shot Peening Parameters on Peening Intensity

P V Sartanpara, Pramila Agrawal, J R Koisha

Open publisher page 0 citations

Abstract

Shot peening is a cold working process used to produce compressive residual stress layer and modify mechanical properties of metals. The change in mechanical properties are measured in terms of shot peening intensity. The influence of shot peening parameters like air pressure, standoff distance, shot media, exposure time and nozzle diameter on shot peening intensity have been analyzed by Analysis of Variance method. This study highlights application of Taguchi technique to optimize effect of the shot peening parameters.
