A manufacturing process of a monobloc vaned disc including a cutout by abrasive water jet of a block of material in general form of a disc, carried out so as to remove material from the block at a level of inter-vane spaces to reveal vane preforms extending radially from a hub, the cutout by abrasive water jet including, for making each inter-vane space: a first triple-axis cutout of a piece passing through the thickness of the block, used such that the cutout piece escapes from the block automatically by gravity; followed by at least one enhancement cutout.

Optimised manufacturing process for a vaned monobloc disc by abrasive water jet

A manufacturing process of a monobloc vaned disc including a cutout by abrasive water jet, including: a continuous cutout, with an ejection head of a tool opposite a first face of the block, of a piece passing through the thickness of the block, the continuous cutout revealing a junction line between a second face of the block opposite the first, and the surface of the block cut out by the abrasive water jet; followed by at least one enhancement cutout, with the ejection head opposite the second face of the block, of a piece extending only over part of the thickness of the block, and integrating at least part of the junction line.
