摘要:

通过对高熵合金进行三维槽铣和侧铣的铣削力仿真分析,研究了不同加工参数对铣削力的影响规律.针对FeCoNiCrAl0.1,FeCoNiCrAl0.5,FeCoNiCrMo0.1三种铸态高熵合金设计正交与单因素铣削实验,通过测量实验中的铣削力,探讨了不同加工方式、铣削参数、刀具和不同元素成分及含量对铣削力的影响规律.仿真及实验结果表明:随着铣削速度的增加,铣削深度和进给速度的减小,槽铣和侧铣的铣削力都减小,相同加工参数下槽铣的铣削切向力和法向力分别比侧铣高404.30%和761.06%. Al元素含量高的高熵合金铣削力大.HMX涂层刀具的铣削力小于SGS涂层刀具,铣削力平均降低10.6%.实验结果为高熵合金的高效加工提供了理论参考.

Abstract:

The effect of different machining parameters on the milling force of high?entropy alloy(HEA) was studied through the simulation analysis of 3D slot milling and side milling. The orthogonal and single?factor milling experiments of FeCoNiCrAl0.1, FeCoNiCrAl0.5, and FeCoNiCrMo0.1 as?cast HEAs were designed. By measuring the milling force in the experiments, the effects of different machining methods, milling parameters, tools, and elements of HEAs on the milling force were explored. The results showed that with the increase of milling speed and the decrease of depth and feed speed, the milling force of slot milling and side milling decreases, and the tangential force and normal force of slot milling are 404.30% and 761.06% higher than that of side milling under the same machining parameters, respectively. High?entropy alloys with high Al content have higher milling forces. The milling force of HMX tool is smaller than that of SGS tool, with an average reduction of 10.6% in the milling force. The experimental results provide a theoretical reference for the efficient machining of HEAs.
