CAPP（成组技术）..doc

电机制造CAPP系统 摘要 电机生产批量小，品种多，其工艺编制主要依赖于手工，工艺设计繁琐，规范性差，成熟的工艺知识及经验难以保存和借鉴，存在着工艺设计时间长、工艺设计重复性大等问题。因此需要开发一套适合电机生产特点的CAPP系统，解决工艺设计的瓶颈问题。 基于此，辽宁石油化工大学和抚顺煤矿电机厂合作开发了DJ-1CAPP系统。 首先是工艺设计的标准化：根据抚顺煤矿电机厂产品的特殊性及电机零件结构特点，自行设计一个具有一定针对性的13位分类编码系统；将主要生产零件编码，并根据相似性原理将零件分组；采用复合工艺路线法进行成组工艺设计并确定主样件。在此基础上，编制工艺过程工序卡片，形成标准工艺。 然后是工艺库的建立：以抚顺煤矿电机厂工艺文件为基础，将各零件组主样件图形及标准工艺生成工艺数据文件，以备软件调用。 最后是工艺设计的自动化：以Microsoft Visual Studio .NET 2003为开发平台，开发出DJ-1CAPP系统应用软件。本软件通过对零件的编码与检索，用户只需通过交互式输入，即可由系统自动生成加工工艺，并可根据零件特点，对工艺进行任意修改。 DJ-1CAPP系统采用检索式、派生式和创成式相结合方式，综合他们的优点，并在应用成组技术（GT）和人机交互方式作为补充的基础上开发出的一种面向电机生产制造的综合式系统。该系统对电机零件加工工艺过程标准化、规范化具有积极的作用，具有较强的应用价值，对于电机生产企业实现工艺信息的集成管理，提高工艺设计的效率和质量，具有重要的意义。 关键词：成组技术；计算机辅助工艺规程设计；零件分组；成组工艺设计  System of CAPP in the Motor Manufactory Abstract Today, low-volume productions, more varieties, tedious process design, and lack of standards is motors’ manufacturing features. It is a long and repetitive process plan during the course of motors manufactory. So, it needs to develop a set of characteristics for the production of motor CAPP systems and solve the bottleneck problem of process plan. Therefore, Liaoning Shihua University and Fushun Coal Mine Motor Plant have developed the DJ-1CAPP systems. First, it is the standardization of process plan: according to Fushun Coal Mine Motor Plant products particularity and structural characteristics, to design a certain targeted 13 Classification and Coding System, to code for main parts, and in accordance with the principle of similar parts to group, and using composite process method and to carry on Group Process plan and determine the prototype parts. based on this, to draw up process processes cards and form a standard processes. Second, it is establishment of process databases: based on process documents of the plant, To form process data documents with prototype parts graphs and standard process documents, and to prepare for software to use. Finally, it is the Process plan Automation: Microsoft Visual Studio. NET 2003 for th
