OPTIMISED METHOD FOR PRODUCING A ONE-PIECE BLADED DISC (BLISK) BY ABRASIVE WATER-JET CUTTING

摘要

The present invention relates to a method for manufacturing a one-piece bladed disc comprising a step of cutting by abrasive water jet comprising: a cross cutting, with the ejection head (116) of the tooling opposite a first face (110a) of the block, of a piece (114a) passing through the thickness of the block, this cross cutting revealing a junction line (121a) between a second face (110b) of the block opposed to the first face and the surface of the block cut by the abrasive water jet; followed by at least one fine cutting, with the ejection head opposite the second face (110b) of the block, of a piece (114b, 114c) extending only over part of the thickness of the block, and incorporating at least part of the junction line.
