IMPROVED METHOD FOR PRODUCING A ONE-PIECE BLADED DISC, WITH TEMPORARY BLADE-SUPPORTING RING

摘要

The present invention relates to a method for producing a one-piece bladed disc, comprising: a step in which an abrasive water jet is used to cut a block of material (100) in such a way as to leave behind preforms (102) extending radially from a disc (4), while keeping the material forming bridging means (112) between at least two directly consecutive blade preforms, the bridging means being radially remote from the disc; and then a step in which the bridging means (112) are removed.
