摘　　要：构建了考虑不同振动方向的车削表面形貌模型,基于模型研究了理想车削、轴向振动车削、径向振动车削对车削轨迹和表面形貌的影响差异。分析了轴向振动车削工况下不同的进给速度、刀尖半径、主轴转速和背吃刀量对表面形貌的影响。研究结果表明:轴向振动车削对表面形貌影响较为显著;轴向振动车削状态下表面粗糙度随进给速度的增加而增加,随刀尖半径的增加而减小,随主轴转速的增加而减小,背吃刀量的变化对粗糙度影响不大。本研究旨在为不同振动车削仿真分析和参数优化提供理论基础。This paper presents a surface topography model considering different vibration directions,investigates the differences in turning trajectory and surface topography between the ideal turning,axial vibration-assisted turning and radial vibration-assisted turning based on this model,and analyzes the effect of different feed rates,tool tip radiuses,spindle speeds and back loads on the surface topography using the axial vibration-assisted turning method.The results show that the axial vibration-assisted turning has a more significant effect on the surface topography.Using the axial vibration-assisted turning method,the surface roughness increases with the increase of feed rate,and decreases with the increase of tool tip radius and with the increase of spindle speed.The change of back feed has little effect on the surface roughness.This study provides a theoretical foundation for different vibration-assisted turning simulation analyses and parameter optimizations.
