Abstract: The trend of industrial globalization puts forward higher requirements for the cultivation of talents in universities and colleges in our country. Graduation design is a compulsory practice for mechanical undergraduate majors, and it is also one of the important ways to cultivate students’ engineering ability. In view of the shortcomings existing in the current graduation design teaching process, this paper takes the professional certification of engineering education as the starting point, focuses on the future development of students and the needs of enterprise engineering technology, and adopts the training mode of school-enterprise integration and double tutorial system. By constructing the project-driven teaching mechanism featuring inquiry learning, diversified evaluation and whole process management, the ability-oriented training purpose required by the professional accreditation of engineering education is achieved. At the same time, based on the technical upgrading projects, the community of interests between enterprises and universities and colleges can be constructed, which can effectively promote the integration of industry and education.
