摘　　要：基于固体润滑技术、刀具热传导理论以及网格重划技术,建立了刀具-工件的DEFORM-3D有限元模型,对MoS2、WS2、Sb2O3固体润滑涂层的高速钢刀具切削加工过程进行仿真。通过与切削试验的对比,验证了不同进给量、切削深度下的切削力、切削温度变化规律的仿真结果的准确性。结果表明:该固体润滑涂层应用于中低速干切削中,可有效降低切削热和切削力、延长刀具使用寿命。Basing on solid lubrication technology,tool thermal conduction theory and remeshing technique,DEFORM-3D finite element model of tool-part was established,and the cutting processes of new coated high-speed steel tools with MoS2 ,WS2 and Sb2 O3 were simulated. By contrast with the cutting test,the accuracies of the variations of cutting force and cutting temperature in different feed rate or back cutting depth were verified. Simulation results show that the new type of coating can reduce the cutting heat and cut-ting force of tools and extend tool life in dry cutting at middle-low speed effectively.
