VORRICHTUNG ZUR UEBERWACHUNG VON ROTIERENDEN WERKZEUGEN

摘要

A device for monitoring rotating tools, in particular twist drills, has at least a distance sensor that detects the distance between a plane of reference and the area of the tool that is acquired by the sensor, and a control unit that evaluates the output signal of the sensor. The device is characterized by the fact that the area of the rotating tool acquired by the sensor is large in comparison with typical deformation of the tool, so that the output signal of the sensor corresponds to an ''average'' distance.
