Application of 3D FEM to Die Design in the Radial Forging Process

Radial forging is an open forging process used for reducing the diameters of shafts,tubes, stepped shafts and axels, as well as for creating internal profiles for tubes such as rifling the gun barrels. Most of previous studies conducted on the radial forging process have used axisymmetric models to investigate the effects of die shape on deformation. In order to design a hammer die for radial forging process, a full 3D model of the process is needed to consider the effects of die shape in the cross-section area on deformation. In this study, finite element method is used to model the radial forging process and to study the effects of die shape in the crosssection area on deformation.
