<p>The present invention relates to a method for manufacturing a one-piece bladed disc comprising a step of cutting by abrasive water jet of a block of material (100) in the general form of a disc, carried out so as to remove material from the block at inter-blade spaces so as to reveal preforms of blades extending radially from a hub, the step of cutting by abrasive water jet comprising, for the production of each inter-blade space: a first three-axis cutting of a piece (114a) passing through the thickness of the block (100), operating such that the cut piece escapes from the block (100) automatically under gravity; followed by at least one fine cutting operation.</p> |
