Monitoring embossment depth

In embossing machines, car body IDs are punched into the vehicle frame. The embossment depth must be in a defined tolerance range. In order to position the embossing tool, laser triangulation sensors from Micro-Epsilon detect the distance between the embossing tool and the component. After the embossment is finished, the sensor measures the profile of the embossment and ensures that all characters are embossed to the required depth.
