A method is proposed for achieving a topological tooth profile using a conventional grinding machine which cannot feed a shaving cutter toward the face width direction and generates an involute form by pitch band and pitch block with offset from the center of rotation. The first report showed an analysis method for generating shaving cutter profile by a conventional grinding machine based on a conjugate principle between grinding wheel and cutter. This report introduces a method of optimization in order to determine grinding machine setting conditions and cone grinding wheel profile which can generate a shaving cutter with the desired tooth profile. RMS value of the profile difference between ground cutter and defined cutter is adopted as the objective function for optimization. By analyzing a helical gear with bias modification, it is proven that the developed method can determine machine setting conditions and grinding wheel profile.
