The paper presents the results of numerical modeling of a cross-wedge rolling process for producing a stepped shaft. The modeling was performed with commercial software Forge NxT 1.1 using the finite element method. The numerical analysis enabled the determination of changes in the shape of the workpiece, effective strain, damage function and temperature distributions, as well as variations in the forces and torque acting on the tool. The numerical results demonstrate that personal computers can today be used to model even the most difficult cases of the cross-wedge rolling process, in which complex shapes of the tools and thermal phenomena occurring during the forming process have to be taken into consideration.
