大进给铣削沉淀硬化不锈钢刀具失效分析及切削参数优化
Tool Failure Analysis and Cutting Parameter Optimization of Coated Carbides in Precipitation-hardening Stainless Steel High Feed Rate Milling
摘要
Abstract
In dealing with the problems of low efficiency and server tool wear in high feed milling precipitation-hardening stainless steel(05Cr17Ni4Cu4Nb),a series of single factors and orthogonal ex-periments with coated carbides tool were carried out.An experiential function of tool life was deve-loped based on the experiments by using regression analysis.Tool failure mechanism was analyzed ac-cording to tool wear measurements and wear morphology,the cutting force,cutting temperature and tool stress contour were simulated with finite element analysis.Taking full account of cutting efficien-cy and tool life,the cutting parameters of coated carbides tool in precipitation-hardening stainless steel high feed rate milling were optimized using the tool life-efficiency surface response method by refer-ence to finite element analysis results and the tool life experiential function.The optimal cutting pa-rameters and tool life under this condition were obtained.关键词
