  • Ultrasonic tool confirmation sensor
    Patent number: 5850184
    Abstract: A tool detection system combines a sensor nozzle with an ultrasonic transducer capable of propagating and detecting ultrasonic waves. A wave is propagated in a coolant fluid stream directed at a tool to be monitored. A control unit powers the ultrasonic transducer and contains circuits for analyzing the ultrasonic waves detected by the ultrasonic transducer. The control compares the actual time between the propagation of an ultrasonic wave and detection of an echo wave reflected from the tool, to an expected time. An alarm is generated when the tool is not present as indicated by the actual time exceeding the expected time. An alarm signal generated by the alarm generator either stops the tool or signals an operator that the tool is absent.
