The present invention relates to a method for making a one-piece bladed disk, including: - a step of cutting out, using a jet of abrasive water, a block of material (100), such that the result is pre-formed vane blades (102) that extend radially from a disk, while conserving material so as to form a means for connecting (112) at least two directly consecutive pre-formed vane blades, said connection means being spaced radially from said disk; then a step of removing said connection means (112); and then a step of milling the pre-formed vane blades.
La présente invention se rapporte à un procédé de fabrication d'un disque aubagé monobloc, comprenant : une étape de découpe par jet d'eau abrasif d'un bloc de matière (100), réalisée de manière à faire apparaître des préformes d'aubes (102) s'étendant radialement à partir d'un disque, tout en conservant de la matière formant moyens de liaison (112) entre au moins deux préformes d'aubes directement consécutives, lesdits moyens de liaison étant espacés radialement dudit disque; puis une étape de retrait desdits moyens de liaison (112); puis une étape de fraisage des préformes d'aubes.
