摘要：为了揭示轴承钢硬态切削中切削用量对工件已加工表面残余应力的影响规律,运用金属切削软件AdvantEdge在不同切削用量条件下进行了热力耦合切削仿真。结果表明:硬态切削后工件已加工表面出现残余压应力,随着深度的增加残余压应力值减小并逐渐转变为拉应力;切削速度和进给量对残余压应力影响较大,残余压应力最大值随着切削速度的增加呈先减小后增加的趋势,但作用深度变化较小,进给量增加时残余压应力最大值和作用深度均增加;背吃刀量增加时残余压应力最大值和作用深度变化幅度很小。研究结果可为残余应力控制和工艺参数优化提供理论指导。
A finite element analysis is presented based on the machining simulation software AdvantEdge FEM to investigate the effect of cutting parameters on residual stresses when orthogonal dry cutting hardened bearing steel using CBN tools.The results obtained from this study show that the residual stress at the machined surface is residual compressive stress and become more tensile than compressive beneath the machined surface,the increase of cutting speed leads the magnitude of residual compressive stress to increase firstly then decrease,and the thickness of compressive stress with a little change.The magnitude of residual compressive stress and the thickness of compressive layer increase with the increase of feed rate.The magnitude of residual compressive and the thickness of compressive have changed within a narrow range with the increase of depth of cut.A theoretical guidance for the control of residual stresses and optimization of process parameters can be provided in this study.
