ABSTRACT:
A punching machine has a punch holder driven under the influence of a first control device and a second control device for adjusting a die holder in height relative to a supporting face for sheet type material to be worked. There are measuring devices producing a first data signal representing the height of the die to be used, a second data signal representing the height of the punch to be used and a third data signal representing the thickness of the material to be worked. A data processing device receives the three data signals and in response thereto produces a first control signal fed to the first control device for controlling the punch holder in such a way that at the end of its operating stroke the end of the punch lies at a predetermined distance below the top surface of the material to be worked, and produces a second cotnrol signal fed to the second control device for taking the top surface of the die into a predetermined height setting relative to the supporting face prior to the operating stroke of the punch.
