ABSTRACT:
A method of making a disc having integral blades wherein (1) a billet is preformed with the disc being formed close to final shape except that material needed to complete the outer portion including the blades is placed adjacent the outer edge of the preform; (2) the preform dies are changed and the preform is pressed into its final form. The outer die is formed as a two part die having an inner section and outer section, said outer section placing a holding force on the inner formed section and a forming force on the material needed to complete the disc and blades. The blade dies are formed to have a blade cavity longer than the length of the blade desired so that the ends of the blades can be machined to a desired length.
