"The paper concerns the method of deformation networks in range of stampings drawing from sheet-metal. The influence of circular grids, made by embossing with the use of special apparatus for grid marking, upon sheet-metal is described. The sizes of impressions and the influence of embossed circular grids upon sheet-metal properties were determined for two cases of adjustment of apparatus for making impressions - on impression depth 0,06 mm and 0,05 mm. In both cases of apparatus adjustment from measured values of HV 0,01 in direction normal to the sheet-metal surface in the place under impression and in surroundings followed, that by embossing of impression on sheet-metal the substantial influence upon ferrite grain microhardness does not happened deeper under sheet-metal surface."@en .
