ABSTRACT:
A method of grinding a slot base of a blade retention slot within a rotor disk includes rotationally aligning a grind wheel about an axis of rotation to align a first notch with a first and second opposed lobe of the blade retention slot of the rotor disk; transiting the grind wheel along the blade retention slot that the first notch is passed between a lobe width defined by the first and second opposed lobe of the blade retention slot; rotating the grind wheel about the axis of rotation; and transiting the rotating grind wheel along the blade retention slot to grind a slot base with a rim of the grind disk, the slot base having a width greater than the lobe width of the blade retention slot. A grind wheel includes a rim having at least one notch formed in the rim to grind a slot base of a blade retention slot within a rotor disk.
