Paper Abstract

According to elastic-plastic finite element theory, three-dimensional nonlinear elastic-plastic finite element simulation analysis on optical component material aluminum alloy 2A12 is carried out, and residual stress on machined surface is predicted and calculated, which provide the basis for improving the machining accuracy of optical component. Johnson-Cook's coupled thermal-mechanical model is used as work piece material model, Johnson-Cook's shear failure principle is used as work piece failure principle, coupled thermal-mechanical hexahedron strain hybrid modules and adaptive grid are used to mesh, while friction between tool and work piece uses modified Coulomb's law whose slide friction area is combined with sticking friction. By finite element analysis, simulation results of residual stress on the machined surface is gained under different cutting velocity, tool edge radius, and by analyzing and comparing the results, the basic influence law of various factors on residual stress on machined surface is found.
