Method for manufacturing or for repairing a component of a rotary machine as well as a component manufactured or repaired using such a method

A method for manufacturing a component of a rotary machine, the component extends in an axial direction and a radial direction vertical thereto, and has an inner channel, extending from a first end in a center of the component to a second end at a radial limiting surface of the component and which i...

description A method for manufacturing a component of a rotary machine, the component extends in an axial direction and a radial direction vertical thereto, and has an inner channel, extending from a first end in a center of the component to a second end at a radial limiting surface of the component and which is partially closed. A blank includes the center of the component and is limited by an outer surface in the radial direction. The maximum dimension of the outer surface in the radial direction is smaller than the dimension of the limiting surface in the radial direction, A first subtractive process step is performed such that a part of the channel is manufactured by a machining process, with the part extending from the first end of the channel to the outer surface of the blank. Afterwards the channel is finished by a build-up process on the blank.
