Based on the mechanism of precision forming of camshafts by cross wedge rolling (CWR), the precision forming process of a simple and typical camshaft by CWR was numerically simulated with DEFORM-3D finite element software and an ideal shape was obtained. The FEM result was used to analyze the strain distribution in the work piece during the whole process. The metal flow laws in the axial, radical and circumferential directions were systematically discussed. It is shown that the simulation result is in agreement with CWR experimental data by comparison, indicating that the method of camshaft forming by CWR is feasible.
