Abstract

A component of a rotary machine formed from a blank, the component includes a center, a boundary surface, and at least one inner passage extending from the center up to the boundary surface and being at least partly closed. The inner passage is formed by a first subtractive machining 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 is manufactured by machining production, and subsequently the passage is completed by a build-up production on the blank.
