Abstract: A process for grinding a gear tooth blank to form an involute gear tooth includes the steps: setting a predetermined cutting rate which fails to result in burning between a grinding wheel and the gear tooth blank; determining the area of the tooth face of the gear tooth blank to be removed for respective grinding strokes in accordance with the predetermined cutting rate so that the metal removal amount of respective grinding strokes approaches to a constant except that the metal removal amount of the last grinding stroke may be smaller than the constant; and effecting the relative involute generating movement between the gear tooth blank and the grinding wheel in accordance with the respective areas of the tooth face to be removed for removing the metal within the respective areas from the gear tooth blank in a step-by-step manner to form an involute gear tooth.
