Abstract On the premise of weak substitutability and being often used to manufacture key components of aeroengine, high-efficient and high-quality machining of difficult-to-cut materials such as titanium alloys is facing challenges. Aiming at the problems of poor surface integrity and service performance of titanium alloy Ti–6Al–4V, high-speed cutting tests of titanium alloy Ti–6Al–4V were carried out, and the improvement of high-speed ultrasonic vibration cutting technology on the surface integrity and the wear resistance of machined surface was analyzed, thus providing theoretical support for high-quality machining of titanium alloy Ti–6Al–4V. The results show that compared with conventional cutting, high-speed ultrasonic vibration cutting effectively reduces the surface roughness, and improves surface strength, surface residual compressive stress and wear resistance of titanium alloy Ti–6Al–4V.
