Zusammenfassung:	The present invention is directed to a method of making an automotive part having a spline. Preferably, the automotive part is a high strength automotive part having a relatively high carbon content. The method includes pressing a spline tool having one or more spline grooves into a bore defined by the automotive part so that one or more splines are formed through the displacement of material on the interior of the bore. La présente invention concerne un procédé permettant de fabriquer une pièce automobile pourvue d'une cannelure. De préférence, la pièce automobile est une pièce automobile à résistance élevée possédant un contenu de carbone relativement élevé. Ce procédé consiste à emboutir un outil à cannelure pourvu d'au moins une cannelure dans un alésage formé par la pièce automobile, de telle manière que les cannelures sont formées par le déplacement de la matière à l'intérieur de l'alésage.
