Research on High Speed Face Milling Cutter Based on the Model of Stress Field

摘要

According to the characteristics of high speed face milling process, the models of the stress field for high speed face milling cutter with two sorts of structure are proposed and established. By means of the finite element analysis of the stress field for high speed face milling cutters, the law of influence of the cutter's structure, the cutter's subassemblies and the fixing rake of inserts on the stress field of cutter is acquired under the action of high rotate speed. In this foundation, the model reconstruction and the stress field analysis of the cutter are completed, and the model of evaluation for dynamic cutting performance of high speed face milling cutter is established. The results of high speed face milling experiment and frequency spectrum analysis of dynamic cutting force of the cutter indicate that high speed face milling cutter with the fixing rake of zero degree and less subassemblies takes on better dynamic high speed cutting performance.
