ABSTRACT:
Larger cutting tools which have inherently greater strength can be used to form mounting grooves for side-entry rotor blades when the bottom-most neck of the groove is increased in width in the machining process. The larger width leaves a gap on both sides of the bottom-most neck of the root at a location away from load bearing surfaces.
