"Contribution concerns the method of deformation networks in range of sheet-metal forming. Principle of this method consist in creation of deformation network at sheet-metal blank before forming and evaluation of its deformation at any moment or after forming operation in forming tool. A special apparatus for embossing of circular grids on sheets with continuous regulation of embossing force was constructed. With this apparatus accurate, clear and permanent circles can be applied to the sheet simply, very quickly, without the use of a power source. The apparatus has small dimensions and so it is portable, its cost is low. At drawing of intricate shape stampings from steel deep-drawing sheets the using of impression depths between 0.05 mm and 0.06 mm proved true, which guarantee minimum sheet-metal influence by deformation in places of impressions with contemporaneous good legibility even after great plastic deformation of material." . . . .
