摘要毕业设计是机械学院教学计划中不可缺少的一个综合性教学环节，培养了我们综合运用所需的基础理论、基本知识和基本技能，分析解决实际问题的一个重要环节，它是在每一个教学环节继续进行下去，深化与考验，它与其他教学环节相互补充、它的实践性和综合性是其他教学环节不能代替的，也是实现理论与实践相结合的重要手段。毕业设计的目的是训练我们综合知识能力和技能去靠自己完成自己相关课题的毕业论文，掌握扎实的技术能力和清晰地思维能力，通过毕业设计使我们得到了较强的综合实践训练，并获得实践能力的提高和无比的精神财富。在完成毕业设计时，应注意以下素质和能力的培养：46173
1、培养自己独立解决问题的各种能力。
2、进一步加强理论知识与技能的培养与训练。
3、在毕业设计的整个过程中注意向指导老师及相关老师请教。
4、强调理论联系实践

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;
