negative rake angle

基本解释

This error has influenced the precision of gear, especially, when negative rake angle of gear-shaped cutter is used, the current design method has not reguired the profile precision.
这种误差影响了齿形精度，特别是负前角插齿刀，现行的设计方法不能满足齿形精度。
The maximum stress point moves to compressive stress, depended on the experimental data, when negative rake angle substituted for positive one and other cutting conditions kept fixed.
当其它切削条件一定时，刀具前角由正值变为负值时，极限应力点由拉应力区移向压应力区，并根据实测数据计算出径向应力由正值变为负值。
This paper also discusses bit parameter design to improve the economy of PDC bits, such as negative rake angle and side rotation angle.
本文还介绍了为提高复合片钻头经济指标的钻头参数设计问题，如负前角，侧旋角等。
