摘要/Abstract

摘要： 针对大进给硬质合金刀具铣削沉淀硬化不锈钢（05Cr17Ni4Cu4Nb）寿命短、效率低的问题，采用单因素法和正交试验法开展刀具磨损试验，并进行回归分析，得到了刀具寿命经验公式。利用有限元仿真方法获得了切削力、刀具切削刃温度和应力场分布情况，结合磨损测量结果及磨损形貌分析了刀具的失效机理。根据有限元仿真结果和刀具寿命经验公式，综合考虑切削效率和刀具磨损，运用等寿命-效率曲面响应法进行切削参数优化，得到了刀具的最佳切削参数及在该切削参数下刀具的寿命。

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 experiments 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 according 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 efficiency 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 reference to finite element analysis results and the tool life experiential function. The optimal cutting parameters and tool life under this condition were obtained.

Key words: precipitation-hardening stainless steel, high feed rate milling, tool life, cutting parameter optimization, cutting process simulation
