ABSTRACT:
Various techniques are disclosed for controlling the operation of a workpiece inspection procedure using a battery operated probe to contact the workpiece and transmit information back to a controller in a machine tool system. In one embodiment, battery power is applied to the probe transmission circuitry in response to a flash of infrared radiation. In another embodiment, the probe is turned on by touching the probe against a reference surface. In both embodiments, a timer is provided to automatically disconnect the batteries after a predetermined time period. In such manner battery life is prolonged.
