Abstract: Application type undergraduate graduation design is a very important stage of practice teaching. In mechanical engineering students graduation design process, there are graduation design topic selection unreasonable, the difficulty of the topic is too large, the graduation design started later, the structure design is not suitable for all kinds of problems.Aiming at these problems, this paper summed up the effective measures, and put forward several links focus on grasp through the reform of teaching practice for many years. The results of the reform show that: in recent three years, the quality of graduation design of mechanical major students of this school is greatly improved, drawing ability enhanced, the number of students writing papers and patents before graduation and the employment rate of increase have been greatly improved.
