Abstract
A method and arrangement for detecting a wear limit or break in a cutting edge of a machine tool. At least two conductor paths are embedded in the cutting material forming the cutting edge, one of the conductor paths being part of a closed circuit while the other is part of an open circuit. A signal serving to break off the machining process is produced if either the conductor path disposed in the circuit is interrupted or the open circuit is closed by the creation of a conductive connection between the two conductor paths.
