剃齿过程“中凹”现象产生的原因分析

Analysis of the concave surface formation causes in sheving gear Fan Qingwen et al (14)

用运动学的观点分析了剃齿过程中相对速度对切削角的影响，从而说明切削角的变化是剃齿过程中产生“中凹”

The effect of relative velocity on the cutting Angle in shaving gear has been analysed firsthy in view of kinematics. It is shown that change in cutting angle is one of main causes to result in concave surface in gear shaving.
