摘　　要：文章研究了超声振动辅助对铣削镍基高温合金的铣削力和表面质量影响。针对超声振动特性,建立了超声振动辅助铣削力模型,仿真分析了铣削力与超声振动振幅、频率的关系,设计了普通铣削和超声振动辅助铣削关于铣削力的对比试验,研究了超声振动作用下不同铣削参数对铣削力的影响规律及表面质量的影响规律。结果表明,对铣刀施加超声振动后,在一定范围内,随着超声振幅和频率的增大,铣削力随之减小;在施加超声振动辅助后,试件表面形貌较为圆润,相邻切削痕迹过渡平滑,显著改善了普通铣削加工后表面凸起尖锐,具有较深的沟槽痕迹,相邻切削痕迹明显的缺陷。The work aim to study the influence of ultrasonic vibration on milling force and surface integrity of nickel base superalloy.According to the ultrasonic vibration characteristics,the ultrasonic vibration assisted milling force model is established and the key models of finite element analysis are introduced theoretically.In order to study the relationship between milling force and ultrasonic vibration amplitude and frequency,and single factor and multi factor orthogonal simulation cutting experiment are designed.The results show that when the ultrasonic vibration is applied to the milling cutter,the milling force decreases to a certain extent,and within a certain range,the ultrasonic current increases and the milling force decreases.In ordinary milling,the surface topography of the plough has clear scratch boundary,sharp surface protrusion and deep groove marks,and the adjacent cutting marks do not interfere with each other.After ultrasonic vibration,the surface morphology is more round and the transition of adjacent cutting marks is smooth.
