两阀下面孔及座圈导管孔加工
 
摘  要
本次毕业设计我的设计题目是捷达两阀下面孔及座圈导管孔加工，全篇包括公司背景、加工工艺、加工过程、成品的自检和终检等等。本次实习掌握了，加工中心的基本操作技能，并把学到的东西应用到生产实际中区去。数控技术及数控机床的广泛应用，给机械制造业的产业结构、产品种类和档次以及生产方式带来了革命性的变化。数控机床是现代加工车间最重要的装备。它的发展是信息技术(1T)与制造技术(MT)结合发展的结果。现代的CAD/CAM、FMS、CIMS、敏捷制造和智能制造技术，都是建立在数控技术之上的。掌握现代数控技术知识是现代机电类专业学生必不可少的。
本篇文章共分为四章，由于本人技术水平有限，实习时间较短，难免存在一些缺点和错误，恳请老师批评指证。

Abstract
Here is the text of the abstract. The graduation project design of my topic is JieDaliangfa under hole processing, total includes company background, processing technology, process and product self-check and final inspection, etc. This practice is mastered, common basic skills, tools and learned to central to the actual production. Numerical control technology and the wide application of nc machine tools, machinery manufacturing industry structure, product categories and class and production brought the revolutionary change. CNC machine is the most important modern processing workshop equipment. It is the development of the information technology (1T) and manufacturing technology development (MT). Modern CAD/CAM, FMS, CIMS, agile manufacturing and intelligent manufacturing technology, are built in the numerical control technology. Mastering modern CNC technology knowledge is essential to modern mechanical majors.

Keywords:  This article is divided into four chapters, technical level, because my internship in a relatively short time unavoidably exists.
