机械切削加工制品,最后精加工形成的零件表面质量对其使用性能的影响至关重要,历来受到重视。z向分离型超声振动车削(以下简称振动车削)的表面粗糙度和微观几何形貌国内外已作过大量研究。但是研究振动车削后表层材料物理性能的变化尚少。因此,我们从宏观残余应力和加工硬化两方面对振动车削的表层物理变化进行了研究。并用振动车削加工的
Mechanical cutting products, the final finishing the formation of the surface quality of its performance is crucial to the performance, has always been valued. Z-type separation of ultrasonic vibration turning (hereinafter referred to as vibration turning) surface roughness and micro-geometry at home and abroad have done a lot of research. However, there are few changes in the physical properties of surface materials after vibration turning. Therefore, we study the surface physical changes of vibration turning from two aspects of macroscopic residual stress and work hardening. Vibratory turning and machining
