摘　　要：为更好地了解27SiMn合金钢干式切削过程中的切削特性,在建立材料的本构模型、失效模型、刀-屑和刀-工摩擦力模型、初始和边界条件设置以及刀具热传导方程的基础上,采用Abaqus软件建立干式切削27SiMn合金钢三维有限元仿真模型。运用响应曲面法设计并开展27SiMn合金钢切削实验,将仿真数据与实验结果进行对比分析发现,切削力、切削温度的仿真值与实验值的大小和变化趋势均具有较好的一致性,切削力的相对误差小于5%,切削温度的相对误差小于7%,验证了有限元仿真模型的有效性。To acquire a good understanding of cutting properties in dry cutting process simulation for 27SiMn alloy steel,a three-dimensional finite element simulation model of dry cutting 27SiMn alloy steel was established using Abaqus based on material constitutive model,failure model,tool-chip and tool-friction force model,initial and boundary condition settings,and tool heat conduction equation.To verify the effectiveness of the cutting simulation model,response surface methodology was used to design and conduct cutting experiments on 27SiMn alloy steel,and simulation data with experimental results compared and analyzed.The results revealed that the simulation values of cutting force and cutting temperature had good consistency with the experimental values in terms of magnitude and trend.The relative error of cutting force was less than 5%,and the relative error of cutting temperature was less than 7%,which verified the effectiveness of the finite element simulation model.
