Abstract

An internal core is separated along a horizontal plane delineated at the transition point between the tapered wall portion and the parallel wall portion of the core to divide the core into a tapered wall component part manufactured by a WEDM process to obtain the desired shape and configuration and a parallel wall component part manufactured by a right angle milling or WEDM with a right angle manufacturing process to obtain the desired shape and configuration. The tapered and parallel wall component parts are joined together to form the desired internal core.
