摘　　要：采用田口分析和模型优化相结合的方法,对新型预硬塑料模具钢SDP1的铣削工艺进行优化,建立了粗铣工艺优化模型.通过信噪比(signal-to-noise ration,SNR)和方差分析研究了铣削速度、进给量和背吃刀量对铣削合力及η/Fn值的影响和变化规律,得出了最佳粗加工参数组合,并进行了实验验证.Milling parameters of a new pre-hardened plastic mould steel SDP1 were op- timized using the Taguchi method and model analysis. The optimization model for rough milling was set up. Based on signal-to-noise ratio （SNR） and analysis of variance, influences of milling force, milling speed, feed rate and axial milling depth on the η/Fn value were discussed. Optimal parameters were obtained and confirmed.
