ABSTRACT Graduation design is necessary for mechanical college teaching plan of a comprehensive teaching and training we comprehensive use of the basic theory, basic knowledge and basic skills, to analyze and solve practical problems is an important aspect of it is in every teaching link to go along, deepening and tests, it and other teaching complement each other, complement each other, practice and synthesis is not a substitute for other aspects of the teaching. It is an important means to realize the combination of theory and practice. Graduation design is our comprehensive knowledge and skills training to rely on their own to complete their own related topics of graduation thesis, grasp the technical ability to solid and clear thinking ability, through the graduation design makes me get a strong comprehensive practice training and practice ability raise and the incomparable spiritual wealth.In the completion of graduation design, should pay attention to the following qualities and ability of the training: 1, to cultivate their ability to solve problems independently.
2, to further strengthen the theoretical knowledge and skills training and training.
3, in the whole process of graduation design attention to the guidance of teachers and related teachers to consult.
4, stressed the theory of practice
Key words: drilling four hole machine tool; PLC programmable technology;
