摘要：为了探究切削用量对新型微坑车刀切削工件表面残余应力的影响规律,应用AdvantEdge切削仿真软件,结合单因素和正交实验,通过微坑车刀和原车刀切削AISI_4140仿真及实验验证。结果表明,原车刀和微坑车刀残余拉应力随切削速度增大,先增大后减小,随进给量的增大而减小,总体上,微坑车刀切削工件残余拉应力更小。残余压应力随切削速度增大,微坑车刀切削工件先增大后减小,随进给量增大先增大后减小。原车刀几乎不变。切削用量对微坑车刀切削工件残余应力影响,进给量最大,切削速度次之,切削深度最小。通过实验验证,相同切削条件下,微坑车刀降低了加工工件表面残余拉应力,提高了加工工件表面质量,一定程度提高了工件的服役寿命。
In order to explore the influence of cutting parameters on the surface residual stress of the workpiece of the new type of micro-groove turning tool, the simulation and experimental verification of AISI4140 of the micro-groove turning tool and the original turning tool were conducted by using the AdvantEdge cutting software combined with single factor and orthogonal experiment. The results show that the residual tensile stress of the original turning tool and the micro-groove turning tool increases with the cutting speed, first increases and then decreases, and then decreases with the increase of the feed. In general, the residual tensile stress of the micro-groove turning tool is smaller. With the increase of cutting speed, the residual compressive stress first increases and then decreases, then increases and then decreases with the increase of feed. The original turning tool is almost unchanged. The influence of cutting parameters on the residual stress of micro-groove turning tool was studied. Experimental results show that under the same cutting conditions, the micro-groove turning tool reduces the residual tensile stress on the surface of the machined workpiece, improves the surface quality of the machined workpiece, and improves the service life of the workpiece to a certain extent.
