Machining quality control of marine diesel engine fuselagebased on similar process

The aim is to solve the quality control problem of the boring process of the fuselage of marine diesel engine, and consider the characteristics of the small batch manufacturing mode. In this paper, the theoretical method of group technology was studied, which was applied to determine the similarity of the boring process of the fuselage. In addition, the quality characteristic data of the group process was standardized by applying the relative tolerance method, and the standardized data was checked. In conclusion, the quality control chart which is suitable for fuselage production is drawn to realize SPC quality control of diesel engine fuselage production process, and the proposed method is applied to the machining process of a certain type of marine diesel engine fuselage to verify the feasibility of this method.
