Synopsis: 

The present experimental work was conducted on a lathe machine to establish the effects of various roller burnishing parameters: burnishing force, burnishing feed and burnishing speed on the surface roughness and surface hardness of EN-31 steel. A simple designed roller-burnishing tool was used throughout the experimental work presented in this paper. It was observed that all the parameters studied; effect the surface finish and surface hardness to varying degrees. The surface roughness Ra first decreases and then increases with increasing burnishing force. The effects of burnishing feed and burnishing speed on the surface finish also showed similar trends. Results showed that the burnishing feed, burnishing speed and burnishing force has also significant effect on surface hardness.
