Abstract (English):
A circuit and computations of drawing technology are offered at which a drawing without thinning (convolution) and with thinning (broach) is carried out in a step matrix. Visco-plastic material is used for sheet blanks. A power method of computation with the use of discontinuous fields of traverse speeds is used. There are shown design assessments of a drawing force and material damageability.

Keywords:
drawing, visco-plastic material, power, pressure, damageability
