Title (EN) PRODUCTION AND MEASUREMENT OF WORKPIECES
(FR) PRODUCTION ET MESURE DE PIÈCES
Abstract:
(EN) A workpiece production method is disclosed in which a plurality of nominally similar workpieces are produced in a production process on at least one production machine (e.g. 10). The order or time of production of at least some of the workpieces on the production machine (10) is recorded. At least some of the workpieces so recorded are measured at two or more inspection stations (20, 22, 24). Dimensions or points of one workpiece are measured at one of the inspection stations (20, 22, 24), and corresponding dimensions or points of another of the workpieces are measured at another of the inspection stations (20, 22, 24). The results of the measurements of corresponding dimensions or points made at the two or more inspection stations (20, 22, 24) are analysed together, taking account of the order or time of production of the workpieces. An output signal is produced based on the analysing of the results together. The output signal indicates performance of the production machine (10) or of one or more of the inspection stations (20, 22, 24).
(FR) L'invention concerne un procédé de fabrication de pièces grâce auquel une pluralité de pièces nominalement similaires sont produites lors d'un processus de production sur au moins une machine de production (e.g. 10). L'ordre ou le temps de production d'au moins une partie des pièces sur la machine de production (10) sont enregistrés. Au moins une partie des pièces ainsi enregistrées est mesurée au niveau d'au moins deux stations d'inspection (20, 22, 24). Des dimensions ou des points d'une pièce sont mesurés au niveau de l'une des stations d'inspection (20, 22, 24) et des dimensions ou des points correspondants d'une autre des pièces sont mesurés au niveau d'une autre des stations d'inspection (20, 22, 24). Les résultats des mesures de dimensions ou de points correspondants effectués au niveau desdites stations d'inspection (20, 22, 24) sont analysés conjointement, en tenant compte de l'ordre ou du temps de production des pièces. Un signal de sortie est produit en fonction de l'analyse conjointe des résultats. Le signal de sortie indique les performances de la machine de production (10) ou d'une ou plusieurs stations parmi les stations d'inspection (20, 22, 24).
