摘　　要：对TBPS易切削不锈钢和进口SF20T易切削不锈钢的化学成分、组织结构和力学性能进行对比分析;利用DEFORM-3D软件对两种材料的高速钻削过程进行了仿真研究,通过对比分析高速钻削过程中的钻削力、钻削温度场以及刀具的磨损情况。结果表明:TBPS易切削不锈钢的钻削加工性能优于SF20T易切削不锈钢。The chemical composition,microstructure and mechanical properties of TBPS and SF20 T stainless steel were studied respectively. Then,the high- speed drilling process of two kinds of materials were simulated by DEFORM-3D software. By comparing and analyzing the drilling force,temperature field and tool wear in high speed drilling process,the results show that the cutting performance of TBPS free cutting stainless steel is better than that of SF20 T.
