切断刀的钝化过程取决于其失效机理，硬质合金材料强度低，在纤维施加的应力作用下，切割初期切断刀刃口产生局部断裂，形成尺寸较小的锯齿形缺口，造成锋利度快速下降。

General clue of this paper is simulating wood stress field change in initial cutting stage and working out weighted boundary condition of cutting tools first,and then based on which, finding out shear stress and maximal effective stress when wood cut-ted.Meanwhile,finite element comparative analysis is proceeded on distortion and stress field by changing tool orthogonal rake.

本课题的总体思路是通过大型有限元软件ANSYS来模拟切削初始阶段中木材的应力场变化，进而得出刀具受力的边界条件，依此为基础求出木材受切时的剪应力及最大等效应力，同时通过变化刀具前角分别对受切工件的变形及应力场进行有限元比较分析，从而确定刀具的优化前角；优化前角确定后，再通过对刀具进行强度校核确定后角优化值。
