Roller Burnishing Process on Surface Hardness

Anup Kumar Ranjan

Abstract


Roller burnishing is the procedure which produces a fine surface finish by the planetary rotation of hardened roils over a bored or turned metal surface. Roller burnishing involves plastic deformation of the surface of the work piece to improve surface structure. The most important parameter describing surface integrity is surface roughness. A detailed experimental program was used in this study where specimens were subjected to various levels of feeding speed and burnishing force. In the present study, the effect of process parameters on surface roughness in roller burnishing process has been studied. The experiments have been conducted based on design of experiments (DoE) to reduce the number of trails by varying burnishing speed, burnishing feed and number of passes. The best results were obtained at the lowest value of the burnishing feed rate and maximum burnishing force used in this investigation.
