Numerical analysis of the cross wedge rolling process (CWR) for a stepped shaft

Abstract

The paper presents the results of numerical modeling of a complex CWR process for producing a stepped shaft. The modeling was performed using the Finite Element Method (FEM) based commercial software Simufact.Forming. The numerical analysis enabled the determination of changes in shape of the workpiece, strain and temperature distributions, as well as variations in the forces acting on the tool. The numerical results demonstrate that personal computers can today be used to model even most difficult cases of the CWR process, where complex shapes of tools and thermal phenomena occurring during forming are taken into consideration.
