摘　　要：基于ABAQUS的大变形分析功能,结合单因素正交试验和多元正交试验设计,模拟不同切削参数下PCBN刀具切削Cr12Mo V零件的加工过程,得到各切削参数对工件表面残余应力影响的预测模型,分析了不同切削参数对工件表面残余应力的影响规律,通过对试验结果的极差分析得到最优切削方案。模拟试验所得数据为合理选择切削参数、提高工件表面质量提供了理论依据。Based on the professional deformation analysis capabilities of ABAQUS,combined with the design of orthogonal experiment with single factor and multiple orthogonal experiment,simulated the course of cutting Cr12 Mo V materials with PCBN tool in different cutting parameters,acquired the residual stress prediction model of impact with different cutting parameters on workpiece surface,analyzed the influence of residual stress on workpiece surface with different cutting parameters,and finally got the optimal cutting plan by range analysis of the experimental result. The datas from simulation experiment provides an important theoretical basis for selecting cutting parametersreasonably and improving thequality of workpiece surface.
