The three grinding methods of a conical involute gear are described and it is proved that a conical involute gear can be ground practically. Niles-Type Taper Grinding, in which a Niles-Type gear grinding machine is used, is based on the principle of generating the gear by the generating rack and is the best method to grind a gear with a small cone angle. Table Sliding Taper Grinding, which is based on the principle of Table Sliding Taper Hobbing, is useful for grinding a gear with an arbitrary cone angle. Inclining Work-Arbor Taper Grinding, which is based on the principle of Inclining Work-Arbor Taper Hobbing, is the most useful method for grinding a gear with a constant cone angle.
