Simulation of the high-speed milling temperature of Titanium Alloy Ti - 6Al - 4V

To study of the temperature generating mechanism of Titanium Alloy Ti - 6Al - 4V in high speed, and the influence rule of the milling process parameters for milling temperatures, A temperature simulation model of the milling process was found with AdvantEdge, the relationship between the high speed milling parameters and the milling temperature of Titanium Alloy Ti - 6Al -4V was discussed by the finite element simulation, and the milling process temperature was measured by the half artificially thermocouple methods. The result show that the highest temperature are reached at close to the tool tip in the rack face, the feed per tooth have significant effect on the milling temperature, while cutting depth and milling width have little effect. The milling temperature increase with the feed per tooth increasing, the highest temperature increase with the spindle speed increasing.
