12. Preface of graduation design summary

Graduation design of mechanical manufacturing technology is an important teaching link on the basis of completing all university courses and graduation practice. This design requires that we can comprehensively apply the basic theory we have learned and combine the practical knowledge we have learned in actual production to independently analyze and solve the process problems, and initially have the ability to design the process specification of a moderately complex part (pre-selected valve body) and the ability to draw up the fixture design scheme and complete the fixture structure design by using the basic principles and methods of fixture design. It is also a practical opportunity to be familiar with and use manuals, charts and other related technical materials and write technical documents, laying a good foundation for future work.
