摘要: 在有限元软件AdvantEdge中对工业常用材料7050铝合金的切削加工过程进行了模拟仿真。仿真中所用被加工材料的本构模型为Johnson-Cook模型,通过Hopkinson杆冲击实验得到了7050铝合金该本构模型的参数。通过变化模型的切削速度和切深,观察仿真结果中刀具所受到的切削力和零件表面加工质量,对切削速度和切深度进行优化,并用其优化后的切削参数对实际零件进行加工,结果表明采用优化后的切削参数能明显提高加工质量,说明有限元切削仿真对提高实际加工效率和加工质量具有重要意义。

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
