摘　　要：根据温度场控制方程及其边界条件,建立高速切削的三维有限元分析模型,将切削过程的温度分布和变化情况以及切削速度、进给量和切屑厚度等对切削温度的影响进行仿真分析,与相同切削条件下的二维仿真结果和实际测试结果进行对比,可以得出结论:三维建模仿真得到的高速切削温度变化趋势与相关文献结果基本一致,但三维仿真获得的温度值比二维仿真要高些,并且三维仿真的温度值更接近于实际测量值。According to the temperature field equation and the corresponding boundary conditions, the 3-D Finite Element Analy- sis （FEA） model of High Speed Cutting （ HSC ） is constructed. The temperature distribution and variety trend of cutting process, which are influenced by the cutting velocity, feedrate and chip thickness, are simulated and analyzed. On the same cutting conditions, the results can be summarized as following：the HSC temperature variety trend of 3-D simulation is consistent with the published literatures;the 3-D simulating temperature value is higher than the 2-D, and closer to the fact measuring value.
