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.

Key words:  milling ,  optimization, plastic mould steel
