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.
