Patent
CA 2561811
A milling method and apparatus for the fabrication of components from materials that are difficult to cut for turbo-engines, producing recesses having one or more side walls, in particular for the fabrication of integrally bladed rotors for gas turbines, in which the recesses form flow channels and the side walls form blade surfaces of an integrally bladed rotor, are disclosed. A milling cutter rotates centrally about an axis of a milling machine. The milling cutter additionally executes an eccentric circular motion about a circular path axis at a distance from the axis of the milling machine. The axis of the circular path including the milling cutter executes an advance motion on a straight and/or curved path. The milling cutter includes cutting edges that are contoured with projections and recesses.
