Abstract
Two kinds of austenitic stainless steels, SUS 304 and SUS 316, were milled using TiAIN coated cemented carbide end mill developed for milling difficult-to-cut materials. Tool wear reliability analysis was carried out based on the tool wear progress. Reliability functions ; hazard rate, tool failure probability density and reliability, were derived from the wear data. The features of reliability functions coincide with the cutting characteristics of materials used in this study. Austenitic stainless steel SUS 304 shows a poor machinability compared with SUS 316 and carbon steel S50C.
