Mechanical surface enhancement techniques such as cavitation peening (CP) have various design parameters which can affect the fatigue performance of the part. In this study, a full factorial design of experiment is applied to investigate the effects of cavitation peening process parameters on the fatigue performance of carburized steel. These parameters include standoff distance, cavitation number, nozzle size, and exposure time. The response variables considered in this experiment include residual stress, surface roughness and austenitic ratio. Results obtained from full factorial design of experiment method were compared with the results from literature which applied Taguchi method. The comparison revealed that …
