Finite Element Simulation of Machining 7075 Aluminum Alloy Based on AdvantEdge and Corresponding Experimental Study

Abstract

Abstract: Abstract: The finite element simulation of cutting 7050 aluminum alloy was carried out based on the software of AdvantEdge, and Johnson-Cook constitutive model was chosen for the workpiece material in the model. The parameters for the constitutive model were obtained through the Hopkinson experiment. The cutting forces and surface qualities were observed through different cutting velocities and cutting depths. The cutting velocity and cutting depth were optimized, and the experiment was carried out with the guidance of the simulation results. The machined workpiece obtained from the experiment shows that the optimized cutting parameters can improve the machined surface property greatly, so it can be concluded that the finite element simulation can provide significant guidance to the machining process in practice.

Key words: Advantedge, aluminum alloy, cutting, finite element, constitutive model
