Abstract
A system for numerical control machine tools comprises contact detecting probes, powered by a battery, that transmit radio-frequency signals to associated interfaces. When the probes are not being utilized for checking cycles, they are in a low-energy consumption state, in other words the circuits of the probes are only partially powered. When the need arises, the circuits of a probe are fully powered by the battery, by a radio-frequency activation signal. The procedure for activating a selected probe includes the sending of a generic activation signal from the associated interface, the transmitting of an identification signal from all the probes that have been activated by the generic signal and the sending of a generic confirmation signal from the interface in reply to the identification signal of the selected probe.
