METHOD AND DEVICE FOR CREATING A SYMBOL IN A WORKPIECE SURFACE VIA STAMPING
First Claim
1. A method for creating a symbol in a workpiece surface via stamping, comprising the steps of pressing a stamping needle into the workpiece surface and moving it parallel therewith;
- determining a resultant stamping depth of the symbol using a distance sensor;
mounting the distance sensor on the stamping needle and moving the distance sensor therewith to be used as the distance sensor;
placing the stamping needle on the workpiece surface before the stamping is begun;
measuring a resultant first distance between the sensor and the workpiece surface;
subsequently pressing the stamping needle into the workpiece surface;
measuring a resultant second distance between the sensor and the workpiece surface; and
determining the stamping depth from a difference of the two distances.

Abstract
In a method and a device for creating a symbol in a workpiece surface via stamping (scoring or plastic forming under compressive conditions); the resultant stamping depth is measured and/or regulated constantly by using a distance sensor which is mounted on the stamping needle and is movable therewith. The stamping needle is placed on the workpiece surface before stamping is begun, thereby resulting in a first distance between the distance sensor and the workpiece surface. A second distance between the distance sensor and the workpiece surface is obtained during the subsequent stamping procedure, and when the stamping needle is pressed into the workpiece surface. The stamping depth results from the difference of the two distances.
