摘要：
A punch press, which is controllable by a control apparatus according to a design characteristic curve for the depth of immersion as function of the number of strokes, is provided with a control input, by means of which a correcting value can be inputted. The punch press operates then at a new point of operation. At a change of the number of strokes, the control apparatus computes with the correcting value and the present design characteristic curve a new design characteristic curve. Such punch press allows the production of punched and embossed products at a higher precision within the entire range of number of strokes.
