ABSTRACT:
The invention enables two-way communication to be established between a measuring probe on a machine spindle and the machine using only two wires between the probe and the machine. Communication from the probe to the machine is achieved by causing current changes in an electrical circuit within the probe (due to the probe circuit changing state when a workpiece is detected) to be sensed by a current sensing circuit on the machine to produce an output in the machine circuit indicative of workpiece detection. Communication from the machine to the probe is achieved by varying the voltage supplied to the probe circuit under the control of the machine controller, the change in voltage being sensed by components of the probe circuit to initiate different functions of the probe circuit e.g. re-setting the probe or changing the gain of a component.
