Abstract In the field of aviation manufacturing, high-efficiency and low-damage processing of difficult-to-machine materials such as superalloys, titanium alloys and composites has always been the bottleneck restricting the industry production capacity. With the continuous upgrading of China’s manufacturing technology, frontier technologies such as intelligence, advanced numerical control, advanced cutting tools and advanced cooling have been widely used in the processing of difficult-to-machine materials. However, the traditional continuous cutting mode still fails to make a substantive breakthrough in cutting linear speed of difficult-to-machine alloy, which limits further improvement of its production capacity. In recent years, high-speed wave-motion ultrasonic machining technology has emerged. This technology upgrades the traditional continuous cutting mode to high-speed separate cutting mode, which not only breaks the machining speed limit of traditional vibration cutting technology, but also realizes the high-speed machining of difficult-to-machine alloy materials and greatly improves its machining accuracy, surface integrity and machining efficiency. Based on a brief overview of background and basic principle of high-speed wave-motion ultrasonic machining, this paper focuses on the process principle, process effect and application of high-speed wave-motion ultrasonic machining technology in turning, milling and hole drilling. The process adaptability optimization and application advantages of high-speed wave-motion ultrasonic machining technology are also prospected in this paper.
