摘要: 传统超声振动切削一直没有突破极低分离切削速度限问题,即只有在很低切削速度下才有明显的分离切削降力、降热工艺效果。以解决难加工材料加工效率低、加工质量差为出发点,提出高速超声波动式切削方法,阐明了高速分离、相位控制、切挤一体3方面的基本机理,通过对改善切削加工性、提升刀具寿命、改善表面完整性3个方面的讨论,充分体现高速超声波动式切削技术的优势,丰富难加工材料高表面完整性的加工工艺,为航空航天领域难加工材料高质量加工提供理论和技术基础。

Abstract: 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.

Key words: ultrasonic vibration, high-speed machining, high-temperature alloy, titanium alloy, composite material, surface integrity
