Simulation of micro-milling process is conducted using finite element method. During modeling, the Johnson-Cook's coupled thermal-mechanical model was employed as workpiece material model, the Johnson-Cook s shear failure principle was adopted as work piece failure principle, and the coupled thermal-mechanical hexahedron strain hybrid modules and adaptive grid were used to remesh the workpiece's elements. The friction between the tool and workpiece obeys the amended coulomb's law that combines with the sliding friction and the adhesive friction.
