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.
