ABSTRACT:
To control the operation of a machine tool, which has a tool bit cutting a workpiece, the temperature of a measurement spot or area, such as on the cut surface of the workpiece, is checked by an optical element which collects infra-red radiation and focuses it on a thermal sensor. The temperature read by the thermal sensor is registered in an evaluating device which generates a signal when a predetermined temperature condition is reached for discontinuing operation of the machine tool.
