Abstract:
1. A system for identifying the position of a three-dimensional machine in a fixed frame of reference, said machine resting on an essentially plane support wall associated with a machine stand, the system comprising: a first base for resting at an identified point of the support wall associated with the machine stand, said base being fitted on its top with a bearing platform providing angular indexing about a central axis that is perpendicular to said support wall when said first base is in place; a second base identical to the first base, for resting at an identified point on a support surface associated with the fixed frame of reference; and a multi-axis assembly having two hinged arms that are coupled together and having two endpieces that are coupled to said arms and that have bottom faces that are adapted to bear directly in an angularly-identified position on the bearing platform of a respective one of the first and second bases, each endpiece having a main axis that coincides with the central axis of the corresponding base when said endpiece is in place, said multi-axis assembly also being fitted with integrated angle encoders measuring the respective angles of rotation about each of its axes.
