Abstract (English):
The basic relations for calculating the modes of mold punching a cylindrical hollow billet under viscoplastic conditions are given. The energy calculation method is used in relation to the axisymmetric field of displacement velocities. Theoretical calculations of the work material processing pressure and damage rate are performed.

Keywords:
mold punching, viscoplastic material, velocity, power, pressure, damage rate
