    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.

    Abstract: A disclosed method utilizes virtual representations of gear profiles produced in view of accuracies and capabilities of specific machine and tool combinations to validate profile finishing parameters. The virtual representations are utilized to identify modifications needed to account for process capability and are implemented into the process to change the nominal profile utilized for producing the finished gear profiles. The resulting nominal gear profile accounts for process variations and thereby provides a more accurate and repeatable gear tooth profile.
