Abstract

Framework parts are extensively used in aerospace industry and milling is its main processing method. This study aims at the milling of aluminum alloy 2024-T351. With the analysis of the milling cutter structure, the virtual topology technology was used to carry on the pretreatment of the milling cutter model, and the adaptive meshing technique was applied. Johnson-Cook's coupled thermo-mechanical model was used as the material model of workpiece. Johnson-Cook's shear failure principle was used as the material failure criterion. The modified Coulomb's law whose slide friction area is combined with sticking friction was used to compute the friction between tool and workpiece. And a more realistic three-dimensional finite element model of milling was finally established. The process of chip formation was simulated in this model. The distribution of surface residual stress at different spindle speed was obtained through finite element simulating. And with the analysis of the results, the basic affecting law of spindle speed to residual stress of machined surface was found, which provides a basis for practical machining.
