摘要：
Traditional ultrasonic vibration cutting has not broken the extremely low separation cutting speed limit, that is, only at very low cutting speeds can there be obvious cutting force and temperature reduction. In this study, starting from solving the problem of low processing efficiency and poor processing quality of difficult-to-machine materials, a high-speed ultrasonic vibration cutting method is proposed, and the basic mechanism of high-speed separation, phase control, and cutting-extrusion integration is clarified. Through the discussion of three aspects: improving machinability, improving tool life and improving surface integrity, this method fully reflects the advantages of high-speed ultrasonic vibration cutting technology, and enriches the processing technology of difficult-to-machine materials with high surface integrity. Above all, it provides a theoretical and technical basis for high-quality processing of difficult-to-machine materials in the aviation and aerospace field. © 2022, Beihang University Aerospace Knowledge Press.
