Simulation for Cutting Force and Temperature in High-Speed Milling of TB6 Titanium Alloy

Article Preview

Abstract:

High-speed milling of titanium alloys is widely used in aviation and aerospace industries for its high efficiency and good quality. In order to optimize machining parameters in high-speed milling TB6 titanium alloy, temperature distribution on the workpiece and the tool are analyzed, and the effect of milling parameters on milling force and milling temperature are investigated. The results show that the highest temperature appears on rake face, and near to the tool tip. With increasing of cutting time, heat affected zone on tool is bigger than that on workpiece. Milling temperature is most sensitive to the variation of milling speed, next sensitive to the variation of feed per tooth, and it is least sensitive to milling depth. Milling force is most sensitive to the variation of milling depth, next sensitive to the variation of feed per tooth, and it is least sensitive to milling speed.
