中文摘要：

采用有限元方法Deform3D软件模拟PCBN刀具硬态切削GCrl5的三维正交切削与斜角切削过程。通过改变刃倾角、切削速度和进给量，研究两种切削过程中切削力和切削温度的变化规律并进行试验验证，仿真结果与试验结果取得较好的一致性。

英文摘要：

Finite element analysis Deform3D is used to simulate three - dimensional precision cutting with PCBN cutting tools turning GCrl5, including orthogonal cutting and oblique cutting. The influence of tool＇S inclination angle, cutting speed and feed speed on cutting forces and cutting temperature are studied, the simulation results are compared with experimentally measured data and found to be in good agreement to some extent.
