[Abstract]:The design model of high speed face milling cutter is evaluated based on the coupled field analysis. According to the theory of requirement level, the performance hierarchy structure of high speed milling cutter is given, and the evaluation scheme of high speed milling cutter performance is put forward. In view of the failure characteristics of high speed indexable milling cutter series system and the requirement of dynamic balancing precision of high speed milling cutter, the basic structure of high speed face milling cutter is established, and the material design scheme of milling cutter assembly is obtained by uniform test design method. The design model of surface milling cutter for high speed milling aluminum alloy with diameter of 63 mm was constructed, and the effect of material and rotation speed of milling cutter components on the maximum cutting temperature, maximum equivalent stress and blade displacement was studied by analyzing the thermo-mechanical coupling field of high speed surface milling cutter. The design scheme of high speed surface milling cutter which can be used in high speed milling of aluminum alloy is evaluated and selected, and the test results of dynamic balance precision, safety, cutting efficiency and machined surface roughness of milling cutter are used through the experiment of cutting aluminum alloy with high speed face milling cutter. Test the high speed cutting performance of milling cutter to meet the requirements of high speed cutting.
