Abstract:
A system for identifying the position of a three-dimensional measuring or machining machine in a fixed frame of reference, said machine standing on an essentially plane support surface, wherein:the support surface is fitted with a plurality of interactive integrated bushings, each bushing being fitted with emitter means serving to emit a predetermined code enabling the bushing in question to be identified and to deduce therefrom the coordinates of an associated point of said support surface, each of said bushings comprising a housing integrated in a drilling in an associated surface, said housing containing the emitter means and a position-identifying cone whose axis passes through the identified point associated with said surface, and wherein the position-identifying cone forms a portion of a threaded washer that supports the emitter, said washer being positioned in the housing of the bushing in such a manner that the position sensor is centered on the associated point when pressed home in said position-identifying cone; and the three-dimensional machine is fitted with at least one articulated arm terminated by a position sensor, said arm being fitted with receiver means capable of detecting the code emitted by a bushing amongst the plurality of bushings when the associated position sensor is brought into contact therewith.
