Tooth position measuring device for scraping tool - has sensor on transversely movable carriage, longitudinal tool carriage, displacement transducers, copying sensors and scale sensors
The measuring device includes a sensor on a transversely movable carriage (12) and a longitudinally movable carriage (13) for moving the tool in its longitudinal direction. The sensor comprises a copying sensor (2) controlling transverse carriage (12) motion and a scale sensor (3) offset in the transverse and longitudinal directions so that the copying and scale sensors are associated with reference points at a distance from the blade on the free surface and on the swarf surface respectively. The carriage positions are measured (36,40,43) continuously. A transducer triggers writing of both positions into memory when the swarf surface reference point is reached. USE/ADVANTAGE - For measuring teeth of clearing tool prior to sharpening. Reduces measurement time.
