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

1. A process for manufacturing a monobloc vaned disc, comprising:
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, carried out by a tool including an ejection head and an abrasive water jet and comprising:
a continuous cutout, with the ejection head of the 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 face, and a surface of the block cut out by the abrasive water jet; followed byat 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. |
