The statistical gauge in geometrical verification: Part I. Field of probability of the presence of matter
چکیده انگلیسی

Currently, most measurement and geometrical verification processes are based on the characterization of distances or angles between geometrical elements. In a previous paper, a method was developed for the verification of ISO specifications using the statistical information included in a set of points. This method is based on the development of measurement sequences and hence a sequence of geometrical constructions. The main problem in this verification process is to propagate uncertainties. With a correct expression of a virtual gauge, it is possible to avoid this propagation; indeed by using virtual gauge manipulation, initial best-fitted surfaces are never touched. The aim of this paper is to present a new approach using this statistical information to describe the measured part and develop a virtual gauge system for verification. This will be done in two parts. The first part will focus on the statistical modelling of the measured surface; the second part will describe a verification method based on a virtual, i.e. numerical, gauge.
