Abstract
Machined parts of stainless steels as difficult-to-cut materials are widely used in many industries, which are transportation equipment, electrical machinery, automobile and aerospace industry. This study describes that the characteristics of machined surface by end milling-burnishing method for SUS304 austenitic stainless steel on the vertical machining center. It is found that end milling-burnishing process with using conventional cemented carbide end mill tool can improve finished surface quality of austenitic stainless steel without causing a large change of surface roughness. In this case, the influence of tool wear and surface roughness is discussed. As the result of experiments, width of each cutting edge flank wear land in end milling-burnishing method greatly influences the surface roughness. Finished surface of SUS304 has a surface roughness Rz of 0.18 μm.
