Abstract
A method is provided for machining a slot having a slot base in a turbine engine rotor disk. The method includes forming a preform slot that extends along a longitudinal axis through the rotor disk. The preform slot includes a preform slot endwall connected laterally between a first slot sidewall and a second slot sidewall. A cutting tool is rotated about its axial centerline, which is substantially parallel to the longitudinal axis. The preform slot endwall is machined with the rotating cutting tool to form the slot base.
