Abstract This paper aims at the problem of the attitude adjustment and the high-strength eccentric hole processing during docking of the wing and fuselage, the tail and fuselage of the large amphibious aircraft. Based on the hole drilling technology of automatic feed drilling, a technological test plan for the machining of high-strength eccentric holes for aircraft docking was designed. Then determining the technological parameters of machining high-strength eccentric holes by automatic feed drilling. At the same time, the aircraft wing body attitude is analyzed through the laser tracker to ensure the docking of the wing and fuselage, the tail and fuselage of the large amphibious aircraft and meet the requirements.
