Abstract
La présente invention concerne une méthode mise en œuvre par ordinateur pour effectuer un contrôle dimensionnel d’une pièce fabriquée à partir d’un modèle numérique. Le procédé comprenant les étapes de recevoir une représentation tridimensionnelle de la pièce, ladite représentation provenant d’une mesure effectuée sur la pièce fabriquée, à partir de ladite représentation tridimensionnelle, obtenir une représentation bidimensionnelle de la pièce fabriquée par projection dans un plan commun ledit plan commun étant perpendiculaire à un axe de la pièce ou comprenant un axe de symétrie de rotation de la pièce, et de comparer la représentation bidimensionnelle de la pièce fabriquée avec un seuil pour effectuer le contrôle dimensionnel. L’invention concerne aussi un procédé pour effectuer un contrôle dimensionnel et un programme d’ordinateur correspondant. Figure pour l’abrégé : Figure 1.The present invention relates to a computer-implemented method for performing dimensional control of a part manufactured from a digital model. The method comprising the steps of receiving a three-dimensional representation of the part, said representation coming from a measurement carried out on the manufactured part, from said three-dimensional representation, obtaining a two-dimensional representation of the manufactured part by projection into a common plane said plane common being perpendicular to an axis of the part or comprising an axis of rotational symmetry of the part, and to compare the two-dimensional representation of the manufactured part with a threshold to carry out the dimensional control. The invention also relates to a method for carrying out dimensional inspection and a corresponding computer program. Figure for abstract: Figure 1.
