高速铣削 NAK80模具钢的铣削力试验研究

摘要

In order to research the effect of milling parameters on milling forces by milling speed v, axial depth of milling ap , feed rates per tooth fz , and radial depth of milling ae , the high speed milling experi-ments on NAK80 die steel with TiAlN coated tools was carried out .The results showed that the milling force decreased with the rising of milling speed , per tooth feed and radial depth of milling , whlle in-creased with the axial depth of milling .On the basis of the single factor experiment results , the regres-sion prediction mathematics model for milling forces were established by linear regression analysis .%为获得铣削速度v、背吃刀量ap、每齿进给量fz 和径向铣削深度ae 对铣削力的影响规律，利用TiAlN涂层刀具进行了高速铣削NAK80模具钢试验。结果表明，铣削力随着铣削速度的增加而减小，随背吃刀量的增大而增大，并随每齿进给量和径向铣削深度的增加而增加。在单因素试验结果的基础上，应用线性回归分析方法，建立了铣削力的回归数学预测模型。
