摘　　要：采用有限元分析软件Deform,对PCBN刀具断续车削淬硬钢(Cr12Mo V)进行了有限元仿真。通过仿真结果分析了切削力的大小、切削温度及刀具磨损量的分布情况,并得到了相应的变化曲线。此仿真结果对断续切削工艺效果的预测和优化及刀具使用寿命的评估和计算具有一定的指导意义。Based on finite element software deform of PCBN cutting tool intermittent cutting hardened steel（Cr12Mo V） has carried on the finite element simulation. Through the results of simulation analysis of the size of the cutting force,cutting temperature and tool wear volume of distribution,and corresponding curves are obtained. The simulation results has a certain guiding significance to the effect of prediction and optimization of the intermittent cutting process and assessment and calculation of service life of cutting tools.
