On the premise of weak substitutability and being often used to manufacture key components of aero-engine,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.
