A new approach for the metrology on Coordinate Measuring Machine (CMM) is presented. It is based on the utilization of virtual gauges. The originality of the presented virtual gauge model is the notion of "fitter gauge" which develops the traditional possibilities of gauges. This model allows the verification of functional specifications of the geometrical tolerancing. An example of inspection of a pattern of hole illustrates the method. The gauge model is based on the TTRS model [1] and its numerical implementation on the small displacement method [2].
