The invention relates to a method for optimizing design of a straight-tooth gear shaper cutter. The method is characterized by at least comprising the following steps that 1, the number Z0 of teeth of the gear shaper cutter is determined; 2, the maximum modification coefficient X0max is determined; 3, the minimum modification coefficient X0min is determined; 4, according to the number Z0 of the teeth, the maximum modification coefficient X0max and the minimum modification coefficient X0min in the steps from first to third, the distance from the fundamental section of the gear shaper cutter to the front end face of the gear shaper cutter and tooth profile parameters of the original section, the front end face and the inspection section of the gear shaper cutter are calculated; 5, the gear shaper cutter is designed according to the parameters calculated in the fourth step, and machining is conducted on a cut internal gear. The straight-tooth gear shaper cutter designed through the method has the advantages of being high in precision, reliability and efficiency, the manufacturing cycle of a gear cutter is shortened, and the manufacturing cost is reduced.
