    • A process for the manufacture of a synchronizing component, provided with ahort toothing having undercut teeth, for a shift transmission by precision forging, in which the teeth, the radially inner side of which lies against a common cylindrical surface and the base of which is placed on a common lower plane surface, being first manufactured with parallel tooth flanks and then subjected to final clenching, permits especially precise formation of the coupling surfaces, the following process steps being essential:(a) by means of preliminary forging a semi-finished product is produced the short toothing of which has teeth (7) having excess dimensions exceeding the finished tooth head (10),(b) by means of one or more subsequent calibrating strokes the cold semi-finished product is acted upon in such a manner that(aa) firstly the tooth head (10) are subjected to preliminary clenching, the radially outer sides of the teeth being supported on the forging-die side,(bb) simultaneously with the preliminary clenching operation, or by means of a further calibrating stroke, by rounding out the tooth flanks (9) to the lower plane surface (5), cold compacting is produced in each case in the base region of the teeth (7),(cc) during the final clenching operation the tooth heads acquire a roof-shape and the tooth flanks acquire an obliquity corresponding to their undercuts.
