PARAMETRIC OPTIMIZATION OF ROLLER BURNISHING PROCESS FOR SURFACE ROUGHNESS AND SURFACE HARDNESS

Mechanical Engineering, Production Engineering

Now a days, manufacturing industry expected more service life of the components without increasing the production cost. This led to development improvised and versatile manufacturing processes that address these expectations. The service behavior and life of the components depend mostly on the surface properties. For this reason, significant attention has been paid to the post-machining operations, because the conventional machining processes like turning, milling etc. produce surfaces with inherent irregularities and imperfections. So there is need for a surface finishing operation that nullifies these irregularities. Burnishing is one of the surface finishing process, which does not involve material removal, but improves the surface properties by deforming the surface plastically. Here SS410 steel is used for making shafts with good surface finish and hardness by the roller burnishing process. The present study aims to achieve high performance of roller burnishing machine, experiments is carry out to find effect of input parameter on output performance parameter. The experimental data will be optimizing by full factorial methodology, and conclude optimal set of parameter by Response surface methodology or Regression analysis.
