Beschreibung
Zusammenfassung:	A method for manufacturing a metal alloy part for an aircraft turbine engine, the method including the steps of: (a) producing a blank of the part by additive manufacturing by laser fusion on a powder bed, and (b) abrasively machining the blank to obtain the part, the machining being carried out by vibratory finishing by immersing the blank in an abrasive composition contained in a tank subjected to a vibratory movement, the abrasive composition having an abrasive element formed by alumina particles, a carrying element formed by copper particles, and a liquid.
