摘　　要：以刚塑性有限元理论为基础,采用有限元仿真技术,对金属正交切削过程中切屑成形进行了模拟仿真,得到了不同的刀具前角和摩擦条件对切屑形状的影响规律。对二维切削过程进行加工实验,结果表明切削模拟结果与实际加工情况比较吻合,可以为实际加工提供参数选择的依据。Based on the rigid-plastic FEM principle, the formation of chip metal orthogonal cutting Process is simulated using finite element simulation technology. And a rule of chip formation along with change of cutting tool front angle and the friction coefficient is obtained. The 2 - D cutting process test is operated, the results show that cutting simulated results agreed well with the actual operation performance, which can provide parameter choice for the actual operation performance.
