摘要

A study was undertaken to investigate the performance of PCBN tool in the finish turning GCr15rnbearing steel with different hardness between 30-64 HRC. The natural thermocouple was used to measure therncutting temperature, tool life and cutting temperature were investigated and compared . The objective was torndetermine the influence of the workpiece hardness on changes in cutting temperature and tool wearrncharacterize. According to experimental results, the critical hardness when turning hardened GCr15 bearingrnsteel with PCBN tool is about HRC50.
