| Abstract: | Various experiments were performed to investigate the wear mechanism of polycrystalline cubic boron nitride tools used for machining hardened steels and cast iron. Three main effects were found that are responsible for PCBN tool wear: oxidation wear of the tool, interdiffusion were of elements between PCBN tool and workpiece interface and tool material microfracture. |
