Flat diamond sliding burnishing surface roughness investigation

Abstract

The sliding diamond burnishing process is one among many burnishing post-machining processes applied for surface integrity enhancement purposes. This experimental study aims to investigate the effect of burnishing parameters on the surface roughness of the product. Taguchi design was used, and the machining parameters considered were burnishing force, feed rate, and the number of passes with three levels each. C45 steel alloy workpieces were face milled with the same machining variables and their surface roughness was measured before and after the diamond sliding burnishing process. Enhanced surface roughness was achieved with increasing burnishing force and minimum feed rate and higher number of passes.
