Research on Conventional and High-Speed Machining Cutting Force of 7075-T6 Aluminum Alloy Based on Finite Element Modeling and Simulation

In current industrial practice, the finite element modeling of metal cutting process is essential. this paper, analysis conventional and high-speed 7075-T6 aluminum alloy carried out. A model was developed using Johnson Cook instant on equation to investigate milling behavior under conditions. The forces in X-direction, Y-direction, Z-direction were predicted analytically for five groups different models with material constants, results compared experimentally determined influence constitutive parameters simulation alloy. showed that are inconsistent higher speed Under conditions, JC4 predicts factor good agreement experimental results, while JC5 but has applicability predicting machining performance. Only data obtained by covering real strain, strain rate temperature range determine constant can accurately predict force all directions.
