Abstract
A process for manufacturing a single-piece blisk, including: using an abrasive water jet to cut a block of material, so as to create blade preforms extending radially outwards from a disk, while keeping material to form a connecting mechanism between directly consecutive blade preforms, the cutting being done such that the connecting mechanism approximately forms a ring at a radial spacing from the disk, connecting the blade preforms together at a radially inwards distance from their tips, and then removing the connecting mechanism.
