With the rapid development of aviation industry and iterative renovation of aeronautical technology,it makes new demands on the personal training of aeronautic manufacturing.Nowadays the traditional teaching methods in aeronautic graduate courses is lagging behind the modern manufacturing technology.The graduates are difficult to apply the theoretical knowledge in the practical aircraft fabrication.This paper introduces the augmented reality(AR)technology to the practical teaching for graduates of aeronautic manufacturing.The developed teaching cases of aircraft assembly guidance based on AR technology is applied in the corresponding practical courses.The graduate students could quickly master basic theories,applied technology,software design concerning aeronautics.The case teaching method proves to have many advantages over traditional ones.
