FIELD: machine building.
SUBSTANCE: form block is made of interconnected sections attached to single platform. A template jig is mounted on guide elements from the side of working surface of the form block; the template jig determines arrangement of base orifices in a sheet work-piece. Removable fixing pins are inserted into base orifices in the sheet work-piece and into corresponding orifices in the form block. Blank-holders fixing a part are positioned on working surface of the form block. The blank-holders are attached by adjusting screws screwed into a threaded fitting, mounted into a body of the form block behind both internal and external contour of the part. A sheet work piece is first fabricated on the form block of the press of cross fringe, and further with mechanical treatment of a machine with programme numerical control using the same form block as process equipment.
EFFECT: upgraded quality of parts.
