Virtual Gauge with Internal Mobilities for the Verification of Functional Specifications

In this paper, we propose a method that uses virtual gauges based on a minimum number of mathematical tools for the treatment of measured points. We particularly show the immediate way from the expression of a specification to the mathematical method for the verification of a specification and the new functional specification by virtual gauge with internal mobilities. We illustrate this technique in two steps. First, we show how to build a rigid virtual gauge with degrees of freedom with respect to the actual surfaces (minimum material condition), secondly we show the building of a virtual gauge of a functional specification with degrees of freedom between the gauge features. Numerical applications in both stages show the feasibility of our method.
