Abstract

L'invention porte sur un procédé de fabrication d'une population de pièces produites avec un dispositif de fabrication, basé sur une analyse de stabilité d'au moins une dimension caractéristique des pièces, selon lequel : a) On prélève parmi les pièces produites avec le dispositif de fabrication un échantillon (E) comprenant plusieurs pièces ; b) On mesure pour l'échantillon (E) la dimension caractéristique de chaque pièce, et on calcule pour l'échantillon (E) une moyenne X et un écart-type s de la dimension caractéristique mesurée ; c) On calcule pour l'échantillon (E) une densité de probabilité conjointe pdfpop(X,s) à partir de la moyenne X et de l'écart-type s calculés telle que : pdfpop(X,s) = pdfm(X) . pdfs (s) où pdfm(X) est la densité de probabilité de la moyenne X et pdfs(s) est la densité de probabilité de l'écart-type s ; d) On compare la densité de probabilité conjointe pdfpop(X,s) calculée pour l'échantillon (E) à une première valeur seuil de stabilité (Vsi) ; e) On pilote la fabrication des pièces en fonction des résultats de comparaison de l'étape d).The invention relates to a method of manufacturing a population of parts produced with a manufacturing device, based on a stability analysis of at least one characteristic dimension of the parts, according to which: a) One takes among the parts produced with the device for manufacturing a sample (E) comprising several parts; b) The characteristic dimension of each part is measured for the sample (E), and an average X and a standard deviation s of the measured characteristic dimension are calculated for the sample (E); c) We calculate for the sample (E) a joint probability density pdfpop (X, s) from the mean X and the standard deviation s calculated such that: pdfpop (X, s) = pdfm (X ). pdfs (s) where pdfm (X) is the probability density of the mean X and pdfs (s) is the probability density of the standard deviation s; d) The joint probability density pdfpop (X, s) calculated for the sample (E) is compared with a first stability threshold value (Vsi); e) The manufacture of the parts is controlled as a function of the comparison results of step d).
