Abstract

Ce procédé de détermination d’une position d’au moins un insert matériel (2) pour une fabrication d’une aube de turbomachine en cire perdue, comprend : - une génération (E1) d’un modèle numérique tridimensionnel à partir du modèle en cire matériel (1), le modèle numérique tridimensionnel comportant une enveloppe numérique correspondant à l’enveloppe matérielle du modèle en cire, et comprenant au moins un insert numérique correspondant chacun à un insert matériel (2) ; - une délimitation (E2) de l’enveloppe du modèle en cire numérique et dudit au moins un insert numérique dans le modèle numérique tridimensionnel ; - un recalage du modèle numérique tridimensionnel sur un modèle tridimensionnel nominal, - une mesure (E3) d’un écart entre la périphérie externe du modèle numérique tridimensionnel et l’enveloppe du modèle en cire numérique et, - une mesure d’un écart entre la périphérie externe du modèle numérique tridimensionnel et la périphérie externe de l’insert numérique. Figure pour l’abrégé : Fig 3This method for determining a position of at least one material insert (2) for manufacturing a lost wax turbomachine blade, comprises: - a generation (E1) of a three-dimensional digital model from the model in material wax (1), the three-dimensional digital model comprising a digital envelope corresponding to the material envelope of the wax model, and comprising at least one digital insert each corresponding to a material insert (2); - a delimitation (E2) of the envelope of the digital wax model and of said at least one digital insert in the three-dimensional digital model; - a registration of the three-dimensional digital model on a nominal three-dimensional model, - a measurement (E3) of a difference between the external periphery of the three-dimensional digital model and the envelope of the digital wax model and, - a measurement of a difference between the outer periphery of the three-dimensional digital model and the outer periphery of the digital insert. Figure for the abstract: Fig 3
