Machinability for Turning of 1Cr18Ni9Ti Austenitic Stainless Steel with Ceramic Tool
High strength, low thermal conductivity, high ductility and high work hardening tendency of stainless steels are the main factors that make their machinability difficult. In this study experiments for high-speed turning of 1Cr18Ni9Ti stainless steel were carried out with ceramic tools. The influence of cutting speed on tool wear, chip formation as well as chip color, and surface roughness were investigated. A decrease in tool nose wear was observed with increasing the cutting speed up to 210 m/min. Surface roughness (Ra) was also decreased with increasing the cutting speed. Correlation was made between the tool nose wear/surface roughness and the chips obtained at the three cutting speeds of 110, 160 and 210 m/min.
