<p>Provided is a method for manufacturing a screw-shaped tool that enables a screw-shaped tool, which is capable of grinding a face gear with high precision, to be manufactured. This method for manufacturing a screw-shaped tool, which is formed in such a manner that the diameter thereof gradually increases from an axial end to an intermediate section in the axial direction, and is used for cutting a face gear to be machined, involves: setting up, on the basis of a prescribed pinion which is to mesh with the face gear to be machined, a virtual gear that is to mesh with the prescribed pinion, and has a greater number of teeth than the number of teeth of the prescribed pinion; setting up, on the basis of the virtual gear, a virtual inner gear (15) which has the same number of teeth as the number of teeth on the virtual gear, said teeth being on the inside; and setting up, on the basis of the virtual inner gear (15), a screw-shaped grindstone (10) having various elements that are used for cutting the virtual inner gear (15).</p> |
