从齿轮啮合原理入手,导出了单自由度的径向剃齿刀的齿面方程,与双自由度的普通剃齿刀齿 面方程;分析并阐述了径向剃齿法与普通剃齿法在啮合原理上的区别;通过对相同参数条件下 径向剃齿刀和普通剃齿刀的比较,得出了若干结论,为径向剃齿刀的设计提供了理论依据。%The tooth flank equations of plunge shaving cutter and conventiona l shaving cutter are deduced using the engagement principle for single-freedom and two-freedom respectively. The difference between the plunge shaving and the conventional shaving is pointed out from the meshing points of view. By analyzi ng and comparing the resutls, several conclusions are yielded and they are taken as the criteria for designing and grinding a plunge shaving cutter.
