The preprocessor of ANSYS is applied to set up fmite element model for wood cutting based on theoretical anylysis and by applying load,numerical simulation at initial stage when wood cutting is accomplished.

2在理论分析的基础上，应用ANSYS的前处理器建立木材切削的有限元模型，通过施加载荷，计算分析，完成对木材切削初始阶段的数值模拟。

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。
