Abstract:
1. A system for measuring, compensating and testing numerically controlled machine tool heads and/or tables, characterized in that it comprises: at least one support base equipped with a plurality of distance sensors; and at least one device of the gage tool type composed of an elongated cylinder, said cylinder being equipped at one of its ends with connection means for said heads and being equipped at another opposite end with a ball, said ball being placed next to said sensors so that they are able, always and in any position, to measure a distance that separates them from said ball; wherein the system is operatively canceled with processing means, said processing means being adapted, through a single measure obtained by said sensors about a distance that separates said sensors from said ball, to detect the XYZ coordinates of a center of a tool in a position of interest; and wherein said processing means comprise means for performing measure processes for errors that can be modeled, means for performing measure processes for errors that cannot be modeled and means for performing dynamic checks.
