Zusammenfassung:The invention belongs to the field of aviation machinery, and particularly relates to a tolerance optimization method for a die forging. The tolerance optimization method comprises the following steps of: determining the type of tolerance of a die forging of a part to be optimized according to a drawing of the part, dividing into interior tolerance and exterior tolerance, and then obtaining tolerance data. According to the tolerance optimization method, dimensional tolerance optimization is performed on the die forging of a certain series of a certain airplane, and the requirements of numerical control machining and the technical requirements of part design and manufacturing can be met by rationally adjusting the tolerance of the part and the die forging, so that the machining accuracy, the production efficiency and the yield of products are improved, the machining technical difficulty is reduced, and the method has wide applicability and is convenient to implement. For example, the yield is 80 percent, the p
