摘　　要：根据啮合原理推导径向剃齿刀齿面方程,计算其法向修形量,根据齿条展成渐开线齿面原理,建立砂轮磨削剃齿刀齿面模型,以剃齿刀齿面修形量误差平方和最小为优化目标,确定优化砂轮锥底角及安装压力角参数,磨削后的齿面修形两误差达到精度要求,为设计制造径向剃齿刀提供了依据。According to the meshing theory an approach based on plunge shaving cutter tooth surface equation is established,and the topographic error is calculated. According to the rack generating involute tooth surface,a model of grinding plunge shaving cutter is developed,using minimum squared error as the objective function to get the optimal parameters of grinding wheel. The results show that the grinding error meets the requirements of accuracy,which provides the basis for the design and manufacture of plunge shaving cutter.
