Abstract: A method for cutting a blade root retention slot (24) in a turbine engine disk element (20) includes forming a precursor slot (24') in the element. The precursor slot (24') has first (40A, 41A, 42A, 44A, 45A) and second (40B, 41B, 42B, 44B, 45B) sidewalls and a base (46). A rotating bit (120) is passed through the precursor slot (24') to machine the base. The bit rotates about an axis (520) off normal to a direction (512) of passing. A cutting performance of the rotating bit (120) is modeled reflecting a chip trapping intensity parameter (cp) and a heat intensity parameter (HI). At least one parameter of the bit and its passing is selected so as to avoid tool loading where removed chips/swafs stick onto the bit.
