摘要：The article presents an innovative method of manufacturing hollow rail axles using three combined wedge rolls.The proposed solution was evaluated using numerical simulation. Two cases of forming, differing in the wallthickness of the billet, were analysed. The geometry of the formed axles, distributions of the effective strain, tem-perature and damage function were presented. Moreover, the changes to the forces and torques acting on each rollwere presented.
