Three-Dimensional Verification of Geometric Tolerances With the “Fitting Gauge” Model

Thanks to the “fitting gauge” conceptual model, developed in our lab, any geometric tolerance can be interpreted in the form of a virtual three-dimensional gauge, which is able to be assembled with the part to be inspected. From a file containing the sampled points of the part to inspect, the experimental software, using this conceptual model, permits one to build the virtual gauge defined by the geometric tolerance and to check that it can be assembled and adjusted, according to a precise order, with clouds of points representing the part. Checking the geometric tolerances is thus strictly in conformity with their standardized meaning and it is extremely simplified.
