ABSTRACT:
A method for the marking of workpieces and a device for the execution of the method, uses a probe intended for multicoordinate measuring machines and having a chuck for tracer pins. A scriber is inserted in the probe which is connected to a voltage source so that a voltage prevails between the scriber tip and workpiece surface and a fine line is drawn due to the burn-off through voltage spark-over and current flow.
