FIELD: plastic working of metals, possibly manufacture of axially symmetrical and box-shaped parts.
SUBSTANCE: method comprises steps of forcing blank to supporting surface; shaping blank due to acting upon it with load pulses created by means of current discharges in liquid and statically loading it in direction opposite relative to that of pulse load action; successively putting blank material onto punch moved in pauses between load pulses; accumulating material for putting it onto punch in recess filled with formed material moved from periphery; placing sheet blank in turning on lower supporting surface whose height is equal to thickness of blank.
EFFECT: enhanced quality of parts due to elimination of corrugation formation.
