阀体加工工艺规程及钻Φ 10H8孔专用夹具设计
摘要

此次课程设计是对我们所学知识的总复习，同时将过去所学的知识总和在一起，提高我们查询资料和运用所学知识的能力。
拿到零件图，首先我们应当分析研究被加工零件，确定毛坯的种类、制造方法及其尺寸，其次应当正确选择基准，拟定工艺路线，然后可选择机床及工艺设备，计算各工艺，最后设计专用夹具，编写课程设计书。
我们可通过查询书籍来获得以上设计步骤更详细的内容，一本书的资料并不是那么详细，我们应多结合几本书来研究探讨。不同版本之间的书籍存在出入，建议取两者之间的平均数据。有的资料给的不是很详细，上网查询相关内容会更明白，更清楚。

Abstract

This course design is a general review of the knowledgewe have learned, and review the knowledgewe have learned in the long time ago,in order to improve our ability to search for information and apply the knowledge.
When get the parts drawing, first of all,we should analyze it, determine the type ofworkblank, manufacturing method and its size, thenwe ought to correctly choose the standard, draw up the process route, and thenyou can choose machine too ls and equipment, calculate the process data, finally design special fixture, compile the design of course.
We can get more detailed of the design steps by inquiring books. The information of a book is not so detailed. We should combine several books to study and discuss. It is suggested to take the average data between the different editions of the books. Some information is notvery detailed,searching for relevant content onlinewill be more and more clear.

Keywords:valve body； process； special fixture
