Zusammenfassung:	Provided is a method for manufacturing a component of a rotary machine, wherein the component extends in an axial direction (A) and a radial direction (R) that is vertical to the axial direction and has at least one inner channel (7). The inner channel extends from a first end portion (72) of a core (K) of a center portion (6) of the component to a second end portion (71) on a radial limit surface (42) of the component and is at least partially closed. A blank (10) including the core (K) of the component is provided, which is limited by an outer surface (11) in the radial direction (R). A radial direction (R) maximum dimension (D1) of the outer surface (11) is smaller than a radial direction dimension (D2) of a limit surface (42), and a first removal processing step is carried out, in which a part of the channel (7) is formed by machine processing, wherein the part extends from the first end portion (72) to the outer surface (11) of the blank (10). After that, the channel (7) is completed by a build-up process for the blank (10). Also, provided are a corresponding method for repair and a component manufactured or repaired by the method. 회전 기계의 부품을 제조하기 위한 방법이 제안되며, 부품은 축방향(A) 및 이 방향에 수직인 반경방향으로 연장되어 있고 또한 적어도 하나의 내부 채널(7)을 가지고 있으며, 내부 채널은 부품의 중심부(6)에 있는 제 1 단부(72)에서부터 부품의 반경방향 한계 표면(42)에 있는 제 2 단부(71)까지 연장되어 있고 또한 적어도 부분적으로 폐쇄되어 있으며, 부품의 중심부(6)를 포함하는 블랭크(10)가 제공되고, 블랭크는 반경방향(R)으로 외측 표면(11)에 의해 한정되며, 외측 표면(11)의 반경방향(R) 최대 치수(D1)는 한계 표면(42)의 반경방향 치수(D2) 보다 작고, 채널(7)의 일부분이 기계 가공 처리로 만들어지는 제 1 제거 공정 단계가 수행되고, 부분은 제 1 단부(72)에서부터 블랭크(10)의 외측 표면(11)까지 연장되어 있고, 그 후에 상기 채널(7)은 블랭크(10)에 대한 빌드업 공정으로 마무리된다. 또한, 수리하기 위한 대응 방법 및 이러한 방법으로 제조되었거나 수리된 부품이 제안된다.
