This investigation intends to obtain the basic data for applying a newly proposed process utilizing a divided flow to actual gear-toothed machine part. In this first report, a two step forging method is used for the working of a spur gear and the possibility of cold precision die forging for the gear is examined experimentally, when a preliminary closed die forging is combined with the process utilizing the divided flow. In this experiment, the process has been successful in the complete filling up of materials into a die cavity under a low working pressure and is found applicable to various initial thicknesses of materials. Suitable restriction of a centripetal material flow, is found more effective for decreasing the working pressure and saving the material.
