Abstract
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.

A method for manufacturing a metal alloy part for an aircraft turbine engine, the method comprising the steps of:
- (a) producing a blank of the metal alloy part by additive manufacturing using laser fusion on a powder bed;
- and
- (b) abrasively machining the blank to obtain the metal alloy 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 comprising an abrasive element formed by alumina particles, a carrying element formed by copper particles, and a liquid, wherein step (b) further comprises:
- a first cycle of vibratory finishing the blank in the abrasive composition;
- and
- at least one further cycle of vibratory finishing the blank at the start of which some or all of the abrasive composition is evacuated and replaced by a new abrasive composition of the same formulation,
- wherein the orientation of the part in the tank is changed between two successive cycles of vibratory finishing.
