Fine machining process of cylindrical surfaces exposed to the high exploitation loadings has to ensure acceptable surface quality and it’s longer functionality. Quality of surface is an important factor to decide the performance of a manufactured product. The main aim of this research work is to analyse the impact of roller burnishing operation on the cylindrical work material, directed to achieving smaller roughness of test specimens. Roller burnishing is a fine machining process that is used to improve certain physical and mechanical properties. The common parameters in this work selected for burnishing process is to determine and analyse surface roughness. The process parameters considered for roller burnishing process are tool material, force applied and the number of tool passes. The Roller burnishing tool is made of high carbon steel, the burnishing operation is done on copper and brass specimens with different burnishing forces which are varying from 1 to 6 burnishing tool passes. The surface roughness of the specimens was measured before and after burnishing by using surface roughness tester. It has been observed from the surface roughness Ra.
