In this study, elastic recovery phenomenon in cutting process of NiTi alloys was investigated with orthogonal cutting experiments under different cutting speed and feed conditions, this phenomenon is expected to be caused by elastic recovery due to the super elasticity property of NiTi alloys. In this elastic recovery phenomenon, cutting forces did not change significantly in all cutting conditions. Furthermore, tool angle change experiments were conducted by using different cutting tools with different rake angle and clearance angle. Results show that cutting tools with negative rake angle deteriorated cutting performance, while increasing clearance angle to 10° can improve cutting performance of NiTi alloys.
