摘　　要：分析了铲齿成形铣刀用钝重磨后铣刀廓形的变化情况 ,推导了铲磨成形铣刀重磨后的齿形计算公式 ,指出此类铣刀重磨后其设计廓形将发生变化 。The tooth contour of relieved form milling cutters after regrinding is analyzed, and the calculating formula for tooth contour of form milling cutters machined by relief grinding after regrinding is deduced. It's pointed out that the designed contour of this kind of milling cutter should be changed by regrinding, and a method is presented to compensate the regrinding error by adjusting cutter's rake.
