Abstract
This disclosure relates to a design methodology used in manufacturing a broaching tool for cutting slots in aerospace disk applications. The method includes modeling geometry of the slot and the broach tool, which is based upon an initial minimum tooth rise that is determined empirically for the particular disk material. The number of broach inserts and teeth per insert is calculated, and the broach inserts are modeled. The stresses and deformation of the lug are calculated in a finite elements environment based upon simulated incremental broach tool movements. If the lug is not within specifications based upon design constraints, then the broach tool is revised and the simulations are repeated until the slot is within the desired specifications.
