Abstract

A method of manufacturing a torque-transmitting component includes providing a flat blank to a transfer press having a plurality of stations and performing a plurality of pressing operations, in which the flat blank is formed into a cup shape, rough splines are formed on the cup shape, and the rough splines are further pressed to define smooth splines. The component includes a continuous smooth inner diameter defined by a punch of the transfer press and a plurality of smooth splines defined by a die of the transfer press. The minor diameter of the splines is not machined to form the splines.
