Abstract: Titanium Matrix Composites (TMCs) parts usually requires high mechanical performance. The good workpiece surface quality and long tool life is the two target of finishing machining. In this paper, finishing turning tests are performed to investigate the workpiece surface roughness and tool life of machining TMCs with Polycrystalline Diamond (PCD) tools at the cutting speed range 60m/min to 120m/min. The results show that the workpiece surface roughness is obtained range Ra 0.44 to Ra 0.53m. tool life reaches about 10.6min, 7.9min, 7min and 5.5min at the cutting speed of 60m/min, 80m/min, 100m/min and 120m/min, respectively.
