高精度的滚刀铲磨是提高滚刀精度的重要保证，滚刀重磨是延长滚刀寿命的重要措施。传统滚刀铲磨以滚刀前刀面刃形为基准刃形，重磨误差随重磨角度的增大而增大，基于此，提出一种滚刀径向铲磨优化方法。以某一重磨角度下的理论刃形为基准刃形来优化铲磨砂轮截形，在滚刀重磨误差允许范围内，使重磨误差随重磨角度的增大先减小后增大，延长了滚刀使用寿命。对一种单头直槽零前角右旋双圆弧齿轮滚刀进行了滚刀径向铲磨优化实例计算，结果表明该方法可行、有效。
高精度的滾刀鏟磨是提高滾刀精度的重要保證，滾刀重磨是延長滾刀壽命的重要措施。傳統滾刀鏟磨以滾刀前刀麵刃形為基準刃形，重磨誤差隨重磨角度的增大而增大，基于此，提齣一種滾刀徑嚮鏟磨優化方法。以某一重磨角度下的理論刃形為基準刃形來優化鏟磨砂輪截形，在滾刀重磨誤差允許範圍內，使重磨誤差隨重磨角度的增大先減小後增大，延長瞭滾刀使用壽命。對一種單頭直槽零前角右鏇雙圓弧齒輪滾刀進行瞭滾刀徑嚮鏟磨優化實例計算，結果錶明該方法可行、有效。

High-precision hob relief grinding is the important guarantee of hob accuracy ,and hob regrinding is used to prolong hob life .Traditionally ,hob relief grinding took the cutting edge on hob rake surface as reference cutting edge ,and the regrinding errors increased with the increase of regrind-ing angle .Herein ,an optimization method about hob relief grinding was presented .By taking theoreti-cal cutting-edge with a certain regrinding angle as reference cutting edge ,within the permitted regrind-ing error ,the regrinding error will decreases firstly and then increases with the increase of regrinding angle .Finally ,an instance was calculated ,the results verify that the proposed method is feasible and effective .
