Study on Roller Profile for Cam Forming by Cross Wedge Rolling

Based on the motion relation between rollers and work piece during cross wedge rolling (CWR) process, roller profile equations for cam forming were studied. A three-dimensional entity model of the roller was established using the profile equations. Process of cam forming by CWR was simulated by DEFORM-3D. The FEM data was used to analyze dimensional accuracy of the formed cam. Results demonstrate that the equations can be used in roller design for cam rolling.
