Abstract
Blade attachment slots for gas turbine engines are prepared by grinding to a stepped, generally straight sided configuration, semi-finish grinding to an envelope about 0.005 inches to 0.010 inches above the blueprint configuration, and finishing by broaching. This reduces the overall cost of the manufacturing process, permits a more economical use of existing broach machines, and allows greater versatility for short model runs and "just-in-time" production.
