In today’s time, the manufacturing of machines and other components with the highly finished surface are becoming more and more important. Drastic attention is being given on the quality of the surface. Surface finishing is mandatory characteristic of any produced machine. The operation, which can easily improve the surface roughness of machinery parts, is called as Burnishing operation and it is getting evolved day by day. It basically involves plastic deformation of the material. The parameters taken into consideration are burnishing speed, burnishing feed, burnishing force, ball material and number of passes. Mathematical models have been developed in terms of surface roughness and surface hardness for ball burnishing process.
