Three Dimensional Finite Element Simulation for Surface Residual Stress in End Milling Process

Abstract:

This paper proposes a method to simulate residual stress induced by end milling process via 3-D FEM. First, Johnson-Cook material model parameters for a Japanese type of alloy steel (SCM440H) were extracted by a combination method. With the material model parameters, symmetrical end milling process for plate of SCM440H was simulated by FE software to get the residual stress distribution in the machined workpiece. Residual stress measurement experiment was carried out after end milling process to be compared with simulation result to verify the method, which proved that high simulation accuracy can be obtained by extracted material model parameters.
