A technique having superior efficiency for manufacturing a bevel gear forging die is presented. In the present invention, raw material is machined by means of a radius end mill, manufacturing a bevel gear forging die 10 . In recent years, it has become possible to use radius end mills to form complex shapes from raw materials having a high degree of hardness, owing to the fact that NC construction devices and their controlling programs control the deployment of radius end mills, and due to the improved accuracy of the radius end mill itself. By improving the process path of the radius end mill, the inventors have succeeded in creating a process whereby a radius end mill can be used to cut a bevel gear forging die 10 having a side face, a base face, and a diagonal face.
