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/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.

Abstract:

Milling parameters of a new pre-hardened plastic mould steel SDP1 were optimized 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 /Fn value were discussed. Optimal parameters were obtained and confirmed.
