Abstract

The present invention relates to a method for generating at least one connecting web (21) with a reduced thickness during cutting out workpiece parts (19) from a plate-shaped workpiece (16), the cut-out workpiece parts (19) remaining attached to the remaining grid (26) of the workpiece (16) by means of the connecting web (21). According to the invention, the method comprises the following steps: generating at least one connecting web (21) on the workpiece (16) before cutting out the workpiece parts (19), and squeezing the connecting web (21) in the thickness direction (24) of the workpiece (16), at least in a web section (23) adjacent to the workpiece part (19) that has not yet been cut out, so that the squeezed connecting web (21') recedes against at least one of the two plate sides (16a, 16b) of the workpiece (16) in the direction of the workpiece center, wherein the receding of the squeezed connecting web (21') The method comprises a step of retracting the workpiece (16) edges (25a, 25b) thus formed, which form the edges of the workpiece parts (19) that have not yet been cut out; and a step of cutting separating gaps (22) into the workpiece (16) which correspond to the contour of the workpiece parts (19) and are interrupted along the edges (25a, 25b) formed by the retraction of the pressed connecting webs (21'), whereby the workpiece parts (19) remain attached to the remaining grid (26) of the workpiece (16) by the pressed connecting webs (21').
