| description | The invention relates to a method for producing a metal bladed element for a turbomachine of an aircraft, said bladed element comprising at least one blade having a lower surface and an upper surface extending between a leading edge and a trailing edge of the blade, the trailing edge having to have a thickness X1, said method comprising the steps of: a) producing the bladed element by lost-wax casting, and b) finishing the bladed element, characterised in that step b) comprises the chemical milling at least of the trailing edge of the or each blade so as to obtain said thickness X1 which cannot be directly obtained by step a).
Procédé de fabrication d'un élément aubagé métallique pour une turbomachine d'aéronef, cet élément aubagé comportant au moins une pale comportant un intrados et un extrados s'étendant entre un bord d'attaque et un bord de fuite de la pale, le bord de fuite devant avoir une épaisseur X1, le procédé comportant les étapes de : a) fabrication de l'élément aubagé par fonderie à la cire perdue, et b) finition de l'élément aubagé, caractérisé en ce que l'étape b) comprend l'usinage chimique au moins du bord de fuite de la ou de chaque pale de façon à obtenir ladite épaisseur X1 qui ne peut être obtenue directement par l'étape a). |
