Abstract: In the traditional teaching process of the mechanical manufacturing technology course, there are problems such as outdated teaching content, traditional teaching methods, and insufficient practical content. Combining the unique advantages of“Internet +”and big data, this paper integrates concise and refined teaching content, innovates online-assisted offline teaching design, enhances teachers'comprehensive abilities, and strengthens students'innovation ability cultivation through the teaching platform. It forms a set of specific strategies for teaching the mechanical manufacturing technology course in the civil aviation maintenance major of Jincheng College of Nanjing University of Aeronautics and Astronautics. Practice has shown that the classroom atmosphere is more relaxed and diverse, which is conducive to students'in-depth thinking about the logical relationship between knowledge points in learning, and explores new ideas and directions for the teaching of other mechanical courses.
