Verification by virtual gauge using a statistical criterion

Abstract : For the most part, metrology software is currently based on the measurement of distances or angles between geometrical elements. If this method of verification is well adapted to geometrical specification without a virtual state modifier, this is not appropriate for specification based on envelop zone such as in maximal matter condition, for example, for the ISO2692 standard. Usually the least squares best fit method is used to estimate derived surfaces, but the statistical information contained in the acquired coordinates remains under-used. The aim of this paper is to present a new approach for the verification of a part, based on a virtual gauge and using a statistical criterion.
