探讨了剃削过程中刀齿与轮齿接触点的变化规律，根据实测剃削力的大小运用三维有限单元法计算了刀齿与轮齿在接触点的变形，并对变形进行了分析，作出了刀齿与轮齿的弯曲变形曲线。它为进一步研究实际剃削量与变形之间的关系奠定了基础。
The changing rule of contact point between teeth and gear teeth during shaving process was discussed. According to the measured shaving force, the deformation of teeth and gear at the contact point was calculated by three-dimensional finite element method, and the deformation was analyzed. The tooth and tooth bending deformation curve. It lays the foundation for further research on the relationship between actual shaving amount and deformation.
