Simulation of effect of milling parameters on milling force in High-Speed Milling of titanium alloy TC4

A finite element model of milling process of TC4 titanium alloy was developed with AdvantEdge. The influence of milling parameters on milling force was simulated in the High-Speed Milling process with cemented carbide tool. These milling parameters contain spindle speed, feed per tooth, milling depth and milling width. The absolute sensitivity of milling parameters on the milling force was analyzed with the sensitivity analysis method. The results show that feed per tooth and milling depth have significant effect on the milling force, while spindle speed and milling width have little effect. The milling forces decrease with spindle speed increasing, and increase with feed per tooth and milling depth increasing.
