FIELD: process engineering.
SUBSTANCE: invention relates to blanking at dies and can be used in production of thin-wall parts. Prior to placing at die, stack of blanks is formed at fitting process shims from top and bottom and between all stacked adjacent blanks to be jointed together by permanent joint. Produced stack is placed at die pad to cut blanks. Then, process shims are removed. Corrugated sheet is used as said process shims Stack of blanks is formed by fitting sheets in every crimps and locking them therein by permanent joint.
EFFECT: higher quality of parts and process efficiency.
