The paper presents results from machining tests that are carried out to investigate the type of tool wear that occurs in interrupted cutting of Ti6A14V under different process conditions. It has been found that the type of wear is similar to the wear in continuous cutting, but the wear develops much faster. The tests show that by using high-pressure coolant (30 MPa), the cutting speed can be increased by 40 to 50 percent. Edge preparation of cutting tools is of great importance. The best results are achieved with a cutting edge that is slightly rounded. Carbide tools are recommended for the turning operations. Tests show that PCD, CVDD, and CBN have limited usefulness in interrupted cutting.
