A method of manufacturing or repairing a part of a rotary machine, as well as a part manufactured or repaired using such a method Russian patent published in 2021 - IPC B23P15/00 B23P6/00 F01D5/04 F04D29/22 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering and can be used in the manufacture of a rotary machine parts. The part extends in the axial direction (A) and in the radial direction and has at least one inner channel (7). The said channel is partially closed and extends from the first end (72) in the center (6) of the part to the second end (71) in the radial bounding surface (42) of the part. A workpiece (10) is obtained with the center (6) of the part, which is bounded by the outer surface (11) in the radial direction (R). The maximum dimension (D1) of the outer surface (11) in the radial direction (R) is smaller than the dimension (D2) of the bounding surface (42) in the radial direction. Then, the first subtractive stage of the technological process is carried out, when a part of the channel (7) is produced by machining that extends from the first end (72) of the channel to the outer surface (11) of the workpiece (10). Then, the channel (7) is finished by building up on the workpiece (10).

EFFECT: as a result, it is possible to obtain a part with an internal channel of various geometric shapes.
