Abstract The influence of stress and friction conditions on material flow during longitudinal cold rolling of a shaft was investigated. The longitudinal cold rolling method makes it possible to form and finish-up machine parts in the rolling process, which is associated with strengthening of the material due to cold work. The experiments were carried out in order to determine the pressure force at the stage of squeezing on shafts formed by longitudinal cold rolling and made of constructional unalloyed steels S235JR and C45. The experimental results were compared with numerical simulation results obtained by using the MSC��Marc 2010 based on finite element method (FEM). The influence of deformation degree on structural changes and the increase of material strength are shown.
