OPTIMIZED PROCESS FOR MANUFACTURING A MONOBLOC WATER DISC WITH ABRASIVE WATER JET

摘要

The present invention relates to a method for manufacturing a monobloc blisk comprising an abrasive water jet cutting step comprising: - a through cut, with the ejection head (116) of the tool against a first face (110a) of the block, of a piece (114a) passing through the thickness of the block, this through cut revealing a junction line (121a) between a second face (110b) of the block opposite to the first, and the surface of the block cut by the abrasive water jet; followed by at least one refining cut, with the ejection head facing the second face (110b) of the block, of a piece (114b, 114c) extending only over part of the thickness of the block, and integrating at least a part of the junction line.
