高速铣削718模具钢的铣削力试验研究

An experimental study on milling forces in high speed milling of 718 die steel

利用TiAlN涂层刀具对718模具钢进行高速铣削试验研究,获得铣削速度v、背吃刀量αp、进给速度vf和径向铣削深度αe对铣削力的影响规律,为合理选择铣削参数提供可靠的依据。同时,在正交试验结果的基础上,应用多元线性回归分析方法,建立铣削力的回归数学模型,并用R检验和F检验法验证模型的显著性。

High speed milling experiments of 718 die steel were conducted with TiAlN coated tools.The effects of milling speed v,axial milling depth ap,feed speed vfand radial milling depth aeon the milling forces were researched to select reliable milling parameters. On the basis of orthogonal experiment results,a regression mathematical model for milling forces was established by multiple linear regression analysis. Significant test of the model was performed via R and F test methods.
