在制造业信息化环境中，工艺设计是生产技术准备工作的第一步，工艺规程是进行工装设计制造和决定零件加工方法与加工路线的主要依据，它对组织生产、保证产品质量、提高劳动生产率、降低成本、缩短生产周期及改善劳动条件等都有直接的影响，是生产中的关键工作。工艺知识是制造企业中重要的知识资源之一，是使产品设计变为成品的整个制造过程中的基础资源，它对保证产品质量以及提高企业经济技术效益具有十分重要的作用。
夹具的快速设计与制造，己经成为产品快速变换和制造系统新建成或重构后运行的瓶颈，严重地影响制造系统的设计建造周期、系统生产率、质量和成本。目前国内外使用的组合夹具是伴随着大批大量生产的发展而发展出现的，特别是和汽车工业的发展密切相关。组合夹具的使用，缩短了工序时间，降低了加工成本。因此，在何种生产条件下使用哪种类型的夹具才是经济合理的，也就是夹具的经济性，一直都是夹具结构发展和设计的一个主要问题。
这次我毕业设计的课题就是制造业中 XZ25.50 的箱体加工工艺及加工中心、组合夹具设计和数控编程。关键字艺加工中心组合夹具数控编程Abstract
