Date Feb. 2, 1995In forming a helical gear by grinding with a grindstone, the modification accuracy of crowing etc. is improved in such a way that the inequality beta > gamma c is established wherein beta is the helix angle of the helical gear to be ground and gamma c is the inclination angle of the grindstone, and the profile of the grindstone is designed to have a vertical angle which is equal to the inclination angle ( gamma c)of the grindstone.
