摘　　要：旋转超声加工是航空先进材料高效精密低损伤加工的有效方法。在传统的旋转超声加工中,刀具在高速旋转的同时沿着其轴线做超声频率的一维纵向振动。近年来,出现了旋转超声椭圆振动加工这种新型的旋转超声加工工艺,它利用刀具的二维椭圆振动代替传统的一维纵向振动,以进一步提高旋转超声加工的工艺性能。自旋转超声椭圆振动加工技术提出以来,国内外学者开展了大量的相关研究工作。本研究在简要概述旋转超声椭圆振动加工基本原理的基础上,从椭圆超声振动装备和工艺两个方面,总结旋转超声椭圆振动加工的国内外研究进展。在装备研究方面,阐述纵扭、纵弯和双弯等不同形式的椭圆振动产生方法;在工艺研究方面,讨论椭圆超声振动在磨料加工和切削加工等不同加工方法中的应用。基于旋转超声椭圆振动加工的发展现状,结合航空先进材料的加工需求,从加工机理研究、新材料工艺研究、椭圆轨迹稳定性、多自由度超声刀具设计等方面对未来发展趋势进行展望。The rotary ultrasonic machining(RUM)is a superior method for the high-efficiency,precise and lowdamage machining of advanced aviation materials.In the conventional RUM,an ultrasonic-frequency longitudinal vibration is utilized on the high-speed rotational tools.However,in the rotary ultrasonic elliptical machining(RUEM),a2-D elliptical vibration is utilized instead of the conventional1-D longitudinal vibration to further improve the performance of RUM.Since the invention of the RUEM,many relevant researches on RUEM have been carried out.The basic principles of RUEM and vibration types including longitudinal-torsional,longitudinal-bending and double bending are briefly summarized.The research advances of RUEM from equipment to process,and including both abrasive machining and cutting are presented.Furthermore,the development trends of RUEM including machining mechanism,applications on new materials,
