Title (EN) METHOD FOR THE HYBRID PRODUCTION OF A STRUCTURAL ELEMENT COMPRISING ONE OR MORE STIFFENERS
(FR) PROCÉDÉ DE FABRICATION HYBRIDE D'UN ÉLÉMENT DE STRUCTURE AVEC RAIDISSEUR(S)
Abstract:
(EN) The invention relates to a method for the production of a metal structural element from a workpiece, said metal structural element comprising a skin having stiffeners extending therefrom. According to the invention, one portion of the stiffeners is produced by machining, while the other portion is produced by adding material. The material can be added using an additive manufacturing process.
(FR) L'invention est un procédé de fabrication, à partir d'une pièce, d'un élément structurel métallique comportant une peau, à partir de laquelle s'étendent des raidisseurs. Selon l'invention, une partie des raidisseurs est obtenue par usinage, tandis que l'autre partie est obtenue par addition de matière. L'addition de matière peut être obtenue par un procédé de fabrication additive.
