Abstract：The cutting performance comparison of polycrystalline diamond(PCD) and carbide tools was carried out when turning in-suit TiBw/TiCp reinforced titanium matrix composites at the cutting speed of 60~120m/min. Research results show that three-dimensional cutting force of PCD tools is of approximate 77% to 88% of carbide tools, cutting temperature of PCD tools is of approximate 65% to 82% of carbide tools. PCD tools experienced initial severe wear and stable wear stage, while carbide tools only experienced severe wear stage. Furthermore, abrasive wear and adhesive wear are the predominant wear forms of PCD tools. However, crater wears obviously arised on the rake face of carbide tools are adhesive wear and diffusive wear are the main wear forms.
