AUTOMATIC WEIGHING SYSTEM HAVING TELEMETRIC TECHNOLOGY

摘要

Automated gaging apparatus for use with a machine tool system is disclosed. In a preferred embodiment, the apparatus is adapted for use with a touch probe and includes circuitry for frequency shift keying a subcarrier signal responsive to contact occurring between the touch probe and a workpiece. The subcarrier is used to switch a source of microwave radiation, such as a Gunn diode oscillator, on and off at the shifted frequency. The microwave signal is detected by remote receiver, and the detected signal is coupled to the controller for the machine tool system for use in gaging the workpiece.
