摘　　要：基于有限元分析软件ABAQUS的Johnson-Cook材料模型以及断裂准则模拟高速切削淬硬钢锯齿状切屑形态,并讨论刀具前角和锯齿状切屑形态对切削力的影响。研究表明仿真结果和试验结果是一致的,文中介绍的有限元模拟方法可以准确地模拟并预测高速切削淬硬钢时的切屑形成过程。Johnson-Cook materials model and fracture criterion of commercial FE（fmite element） software ABAQUS. was used to simulate the serrated chip morphology during high speed machining hardened steel. The influence of the tool rake angle and serrated chip morphology on the cutting forces was discussed. The investigation indicate that the simulations are consistent with the experiments, the FE simulation method presented can to simulate and predict the chip formation during high speed machining hardened stee accurately.
