Abstract
A method and apparatus for marking a sheet metal workpiece on a punching press. A marking tool, mounted in a holder on the punching press is forced either against the surface of the workpiece, or to a depth into the surface of the workpiece. The workpiece is displaced in its plane, while engaged by the marking tool, in accordance with the desired contour. The marking tool is mounted either in the punch holder or in a holder of the workpiece table. A support roller or ball provides counter-support on the side of the workpiece opposite from the marking tool.

A method for marking workpieces on punch presses, wherein a marking tool having a tool tip is forced by means of a punch stroke onto or into the surface of a sheet-shaped workpiece, which is displaceable in its plane, comprising:
- forcing the tool tip onto or into the surface of a workpiece;
- maintaining the tool in a marking position;
- displacing the workpiece corresponding to contours of a shape to be marked;
- and
- moving the tool away from the workpiece.
An apparatus for marking a sheet-shaped workpiece, comprising at least one marking tool and at least one counter-support on the side of the workpiece located opposite the marking tool, wherein the marking tool has a tool tip, which can be pressed onto or into the workpiece against a restoring force of an elastic element, the marking tool being fixed in place on a punch holder or the holder at the workpiece support table of a punch press, and wherein the counter-support can be fixed in place on the other side of the workpiece.
