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 and burnishing process for SUS304 austenitic stainless steel on the machine tools. Moreover, the difference in the influence of cutting conditions such as up-cut and down-cut processes on the machined surface is discussed. As the result of experiments, feed rates in end milling and burnishing process influences the machined surface texture. Hardness of machined SUS304 as workpiece materials is remarkably much higher than hardness of non-machined SUS304 as raw materials. Finished surface of SUS304 has a hardness of 300 HV or higher in terms of Vickers hardness, which is over twice up to three times higher than the hardness of SUS304 raw metals.
