Patent ID: 6916021

Claim:
A rotor member defining a radial direction, a rotor circumference, and a direction of rotation, the rotor member comprising: a rotor blade having a radial outer tip; shroud arranged at the rotor blade radial outer tip, the shroud comprising a cutting element on a radial outer side, the cutting element defining a chipping tool, said chipping tool comprising a geometrically defined cutting edge, a tool face, and a tool flank, the tool flank being beveled at a relief angle defined with respect to the circumferential direction; wherein the shroud is configured and arranged on the blade in an imbalanced manner in the circumferential direction to tilt under the influence of at least one of centrifugal forces upon rotation of a rotor comprising the member, thermal deformations upon heating of the blade, or combinations thereof, to modify said relief angle upon operation of the blade when operating in at least one of a rotating arrangement, a heating environment, or combinations thereof.
