摘　　要：针对典型的正交切削工艺,采用有限元软件MSC.Marc,基于热弹塑性有限元方法,并在一定的假设条件下,建立了普通硬切削和超声硬切削45淬火钢的二维热力耦合模型。对PCBN刀具普通硬切削及超声硬切削45淬火钢的切削力和切削温度进行了有限元分析。Based on thermo-elastic-plastie finite element equation for simulating the metal orthogonal cutting process, the paper introduces two-dimensional coupled thermo-mechanical models under some assumption with MSC. Mart; for conventional turning and ultrasonically assisted ttmaing 45 hardened steel. The difference of cutting force and temperature distribution both conventional turning and ultrasonically hard turning 45 hardened steel with PCBN are investigated.
