Investigation of Roller Burnishing Process on 20MnCr5 Steel

Burnishing is a mechanical treatment for the quality improvement of rotating components. This work aims to investigate the effect of a burnishing process on the surface integrity properties of 20MnCr5 steel and the resulting performance of this alloy due to the burnished-induced surface properties through a systematic experimental study that was conducted to examine the influence of process parameters. An empirical model involving the number of passes, speed, and feed is developed for out-of-roundness prediction. The results of the Taguchi method are compared with experimental results. It was found that the out-of-roundness obtained is 0.001 microns.
