Process for manufacturing a single-piece blisk with a temporary blade support ring removed before a milling finishing step

摘要

A process for manufacturing a single-piece bladed disk, 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 at least two directly consecutive blade preforms; then milling on the blade preforms so as to obtain profiled blade blanks; then removing the connecting mechanism; then a finishing by milling of the blade blanks, so as to obtain blades with a final profile.
