根据接触轮轴线与叶片型面接触点处最小主曲率方向重合可以达到最好的切削效果，设计了叶片磨削加工过程的运动方式，以此计算出刀位轨迹并进行后置处理得到 NC 代码。

If θ=0?＃, it means that whisker axis is perpendicular to crack face, the energy dissipation caused by whisker-bridge join in zone of crack end achieves its maximum and the reintoughening effect of material achieves the best of all; along with growth of angle θ, the maximum principal stress in the matrix of whisker roots increases, when it achieves its limit, the whisker will be broken and orientation effect will be weakened.

当添加晶须与裂纹面法向形成角度θ时，随角度θ的增加，裂纹尖端拉应力增加。当添加角度较大时，晶须根部基体承受了较大的应力，易遭到破坏性崩裂。同时，晶须内部主应力与晶须轴向之间的角度也随角度θ的增加而增加，造成晶须折断，致使造成晶须拨出的体积分数φap减小，降低了增韧效果。
