Abstract

A method for manufacturing a component of a rotary machine, the component extending to an axial direction and a radial direction vertical thereto, and has an inner channel, extending from a first end of a core of a center of the component and to a second end at a radial limiting surface of the component and which is at least partially closed. A blank includes the core of the component and is limited by an outer surface in the radial direction. The blank is subtractively processed in a first subtractive process step, such that an outer contour is elaborated in the area of the outer surface, which extends in the radial direction, and a part of the channel is manufactured, which radially extends in the blank to the first end. The channel is finished by a build-up process on the blank.
