FIELD: plastic metal working.
SUBSTANCE: invention can be used for manufacture of single and double curvature sheet parts. Proposed method includes series or rotary-local deformation of blank on support deforming member with simultaneous displacement of blank or forming tool relative to each other. Contact compression stresses are created in pattern of plastic contact of tool and blank, stresses are to reach yield point of blank material. Invention reduces number of passes which provides decrease of production expenses and optimization of applied forces at which contact compressing forces reach yield point of blank material.
EFFECT: enhanced operation reliability.
