FIELD: plastic metal working, possibly in aircraft construction, ship building and other branches of industry. SUBSTANCE: method for drawing parts of sheet blanks comprises steps of assembling sheet blank and technological cover plates to pack; drawing pack and stripping technological cover plates from ready part. Technological cover plates are made of material more ductile than that of blank; total thickness of pack is determined according to predetermined relation. EFFECT: enlarged manufacturing possibilities due to elimination of loss of flange stability and lowered deformation effort. 2 dwg
