Numerical simulation of copper ball forming process during skew rolling

The equation of groove surface for skew rolling copper balls was defined, and the characteristic curves were obtained by VC++ programming. A three-dimensional entity model of the roll was established by Pro/E software. The three-dimensional nonlinear finite element method was used to numerically simulate the metal forming process of copper balls by DEFORM-3D analysis software, and the stress and strain distributions were presented from this simulation.
