Abstract
Investigations of the friction influence on the shaping of a flat blank are presented. It is shown that the shaping of a flat blank is determined by kinematic scheme of the metal flow. An intermediate kinematic scheme of the metal flow is proposed. It is proved that as the coefficient of friction increases, the «radial» kinematic scheme of the metal flow smoothly changes to «normal». Evaluation of the friction influence was carried out using computer and physical simulation. For computer simulation the DEFORM program complex was used. Plasticine was chosen as the material for the physical simulation of flat blank shaping. When comparing the results of virtual and laboratory experiments, there is almost complete coincidence.
