英文摘要：

Finite element analysis software AdvantEdge is used to simulate the high speed milling process of avia- tion aluminum alloy 7055, and milling force change curves in the high speed machining are obtained for the single blade. The temperature distributions on the workpiece and tool are predicted under different cutting time, and the temperature distribution curves of rake face and flank face are investigated. The effect curves of milling parameters on the milling force and milling temperature are established for optimizing machining parameters that could reduce the cutting tool wear and prolong the service life of cutting tools.
