Investigation of Variance of Roller Burnishing Parameters on Surface Quality by Taguchi Approach

Surface roughness of engineering parts is a very significant property that effectively influences on the wear and fatigue strength as well as bearing load capacity. there are many methods for improving surface quality of engineering parts such as grinding, lapping and honing. roller burnishing is one of the techniques for improving surface quality. roller burnishing improves surface quality by means of cold working. it depends on many factors such as rpm of work piece, feed rate of burnishing tool and the penetration depth of roller burnishing tool into the work piece. at the present paper, we have tried to investigate the effective factors of roller burnishing and optimize them by means of taguchi approach.
