摘 要
数控机床的出现以及带来的巨大利益，引起世界各国科技界和公益界的普遍重视。发展数控机床是当前我国机械制造业改造的必由之路，是未来工厂自动化的基础。数控机床的大量使用，需要大批熟练掌握现代数控技术的人员。数控技术的应用不但给传统制造业带来了革命性的变化，使制造业成为工业化的象征，而且随着数控技术的不断发展和应用领域的扩大，它对国计民生的一些重要行业的发展起着越来越重要的作用。
随着科技的发展，数控技术也在不断的发展更新，现在数控技术也称计算机数控技术，加工软件的更新快，CAD/CAM的应用是一项实践性很强的技术。如像UG, Pro/E, Cimitron, Master CAM,CAXA制造工程师等。
数控技术是技术行极强的工作，尤其在模具领域应用最为广泛，所以这要求从业人员具有很高的机械加工工艺知识，数控编程知识和数控操作技能。本文主要通过铣削加工滑盖的凹凸模数控工艺分析与加工，总结所学的专业基础知识，全面考虑可能影响在铣削、钻削、绞削加工中的因素，设计其加工工艺和编辑程序，完成配合要求。

Abstract
The advent of CNC machine tool and bring huge benefits, technology and industry around the world. IT seriously. Development of numerical tool is the necessary way of current our country mechanical manufacturing industry technical innovation, is the factory in the future.
The basis of automation. Use of CNC machine tools, need a large number of skilled personnel of modern numerical control technology. The application of numerical control technology not only bring revolutionary change to traditional manufacturing industry, manufacturing industry has become a symbol of industrialization, and with the continuous development of numerical control technology and application field expands, it to the national economy and people′s livelihood some important industry plays a more and more important role in the development.
Along with the development of science and technology, numerical control technology is also in constant development update, now the numerical control also called computer numerical control technology, processing software update fast, the application of CAD/CAM is a practical technology. Cimitron such as UG, Pro/E, Master CAM, CAXA manufacturing engineers, etc.
Numerical control technology is a highly technical work, especially in the field of mould is most widely used, so this requires the employees have high mechanical processing knowledge, knowledge of CNC programming and CNC operation skills. This paper mainly through the milling machining with a CAC technology analysis and processing, comprehensive basic knowledge od my major.
【Keywords】: CNC technology; Stranded milling ,drilling, cutting; part of the process and processing; UG software CNC programming
