Low inertia copying sensor for machine tools - uses ultrasonic pulse transmitter and receiver generating control signals based on pulse travel time

摘要

The copying sensor (2) houses an ultrasonic pulse transmitter (21) directed towards the template. The sensor has a receiver (22) for ultrasonic pulses. The travelling time of the pulse between the pulse transmitter and the receiver is used as proportional time difference for control signals. The copying sensor can be guided only in the longitudinal direction relative to the template configuration.
