利用计算确定剃齿刀齿面修形位置可以减少试验次数。通过对剃齿刀齿面修形位置计算表明：（１）新、旧剃齿刀齿面修形位置到齿顶的基圆展开弧长近似相等，也就是说剃齿刀重磨后的修形位置不必重新计算；（２）用同一把剃齿刀剃削不同齿数的齿轮，剃齿刀的修形位置到齿顶的基圆展开弧长近似相等，也不必按被剃齿轮齿数分档对剃齿刀齿面修形。
Determine the position of shaving cutter tooth surface by calculation to reduce the number of tests. Through the calculation of shaving cutter tooth surface modification position: (1) the new and old shaving cutter tooth surface modification position to the addendum base circle arc length is approximately equal, that is to say shaving cutter after grinding repair Shaped position need not be recalculated; (2) the same gear shaving a different number of teeth shaving gear shaving cutter to the tip of the base circle arc expansion arc length is approximately equal, do not have to be shaved gear teeth sub-file Sharpen the tooth shave
