Exploitation des études de capabilité dans le calcul statistique des tolérances géométriques de localisation.

This paper proposes a new methodology to exploit the capability of manufacturing processes in the statistical calculation of the tolerance of localization of a set of features according to the standards ISO 1101 and ASME Y14.5. The number of features that form the pattern studied, the systematic and random errors in the manufacturing process will all be retained and included in the approach. An explicit mathematical model is developed to identify the statistical distribution functions for different types of localization tolerances. From these distributions, we present a methodology to estimate the values of tolerance that can meet a compliance threshold for a pre-established value, and vice versa. The article also presents a series of charts that are usable in an industrial context. Many examples are illustrated and a case study is presented. [ABSTRACT FROM AUTHOR]
