Abstract
A method of manufacturing a component of a rotary machine, the component has at least one inner passage that extends from a center up to a boundary surface of the component and is at least partly closed, and a blank is provided that includes the boundary surface and a top surface. The Method includes a first subtractive machining step that is carried out in which a part of the passage that at least includes an opening of the passage into the boundary surface as well as a cut-out in the top surface are manufactured by machining production, and subsequently the passage is completed by build-up production on the blank.
