铣削15-5PH不锈钢的切削力研究

Research on Cutting Force of Milling 15-5PH Stainless Steel

为研究铣削加工15-5PH不锈钢时切削参数对切削力的影响规律,基于Deform-3D软件采用正交试验法进行铣削加工仿真,通过15-5PH不锈钢的铣削加工试验对比分析仿真和试验结果,验证了仿真模型的合理性。研究结果表明,影响铣削力的切削参数依次为:每齿进给量f z>径向切削深度a_(e)>轴向切削深度a_(p)>切削速度v_(c);最佳切削参数组合为v_(c)=100m/min,f z=0.02mm/z,a_(p)=1.5mm和a_(e)=0.4mm;切削速度逐步增大会导致切削力降低;增大每齿进给量会提高切削力;径向切削深度的增大会使切削力随之上升,但增长速率较低;切削力随轴向切削深度的增大而增大,增长速率较高。

To study the influence of cutting parameters on cutting force in milling 15-5PH stainless steel,orthogonal experimental method is used for milling simulation based on Deform-3D software,and through milling experiments of 15-5PH stainless steel,the rationality of the simulation model is verified by comparing and analyzing the simulation and experimental results.The research results indicate that the cutting parameters that affect the milling force are as follows:feed rate f z per tooth,radial cutting depth a_(e),axial cutting depth a_(p),and cutting speed v_(c).The optimal cutting parameter combination is v_(c)=100m/min,f z=0.02mm/z,a_(p)=1.5mm,a_(e)=0.4mm.The gradual increase in cutting speed will lead to a decrease in cutting force.Increasing the feed rate per tooth will increase the cutting force,an increase in radial cutting depth will cause an increase in cutting force,but the growth rate is relatively low.The cutting force increases with the increase of axial cutting depth,and the growth rate is relatively high.
