1 附 录 附录 A UG NX Summarized Account Introduction to UG NX UG NX is American Unigraphics Solutions (UGS) companys PLM offering for the core components. UGS company is an American a global supplier of MCAD. PLM Solutions provide a powerful vitality of product lifecycle management (PLM) solutions, including product development, manufacturing, planning, product data management, e-commerce product solutions, but also offers a complete suite of services for product improvement. UG to the automotive and transportation, aerospace, consumer goods, General Engineering and electronic industries through its virtual product development (VPD) provide Multipole, integrated,enterprise-class products and services, including software, and a complete solution. CAD/CAM/CAE three systems tightly integrated. Users use the UG powerful solid modeling, surface modeling, virtual Assembly and create functions such as engineering drawings, you can use the CAE module for finite element analysis, kinematic analysis and simulation, to improve the design of reliability; according to the nts 2 established 3D model, but also by CAM module directly generate CNC code, for product processing. Flexibility in the way of modeling. Composite modeling technology, is solid modeling, surface modeling, wireframe modeling, display the geometric modeling and parametric modeling. Parameter-driven, intuitive, easy to modify the image. Surface design for non-uniform rational B-spline curve-based, you can use several methods to build a complex surface, powerful. A good second development environment, users can use a variety of ways for the second development. Knowledge-driven automation (KDA), facilitate access to and reuse of knowledge. A brief, post processing both CAM software, its main purpose is to build components in the machine tool path (cutting). Generally speaking, you cannot directly transfer CAM software internally generated by the tool path to machine processing, because each type of machine in the physical structure and control system may be different, resulting in the NC program instructions and format requirements may differ. Therefore, the tool path data must be processed to fit each machine and control system for specific requirements. This processing, in most CAM software called post-processing. Post-processing of results is to make the tool path data into machine recognizes tool path data, that is, the NC code. nts 3 Visible, post-processing must have two elements: cutting-CAM homegrown tool path; after the processor is a machine tool and its control system information. UG system provides general post processor UG/Post, it uses the UG internal tool path data as input, output machine after via post-processing recognizes the NC code. UG/POST Organizational structure UG/Post has a strong user of capability, it can be adapted from the very simple to arbitrarily complex machine and control system for processing. Second, UG/Post composition structure mentioned UG/post processor, had to be simple to introduce MOM (Manufacturing Output Manager), i.e. processing output Manager. MOM is UG provides an event-driven tools, UG/CAM module output from it to manage, it is stored in the UG/CAM data to extract the data to generate output. UG/Post it is this tool a specific application. MOM is UG/post processor core, UG/post use MOM to start the interpreter, to explain the program provides the functionality and data, and loads the event processor (Event Handler) and the definition file (Definition File).In addition to the MOM, UG/post is primarily determined by the event generator, the event processor, definition file and output files, and so on of four elements. Once you start UG/post processor to handle UG internal tool path, its processes to the following: event Builder from beginning to end to scan the nts 4 entire UG tool path data, extract each of the events and their associated parameters information, and they are passed to the MOM to MOM; then, delivered each event and its associated parameters to the user in advance to develop good event processor, and collected by the event processor based on their content to decide upon how each event for processing; then the event handler returns the data to MOM as their output, MOM read definition file content to determine how to format the output data; Finally, MOM to well-formatted output data to write to the specified output file. Figure 1 describes the concepts and content. nts 5 附录 B UG NX 简介 UG NX 是美国 Unigraphics Solutions（ 简称 UGS） 公司 的PLM 产品的核心组成部分。 UGS 公司是美国一家 全球著名的 MCAD供应商。 PLM Solutions 可以提供具有强大生命力的产品全生命周期管理（ PLM）解决方案，包括产品开发、制造规划、产品数据管理、电子商务等产品解决方案，而且还提供一整套面向产品的完善服务。 UG 软件 为汽车与交通、航空航天、日用消费品、通用机械以及电子工业等领域通过其虚拟产品开发 （ VPD） 的理念提供多级化的、集成的、企业级包括软件产品与服务在内的完整解决方案。 CAD/CAM/CAE 三大系统紧密集成。用户在使用 UG 强大的实体造型、曲面造型、虚拟装配及创建工程图等功能时，可以使用 CAE模 块进行有限元分析、运动学分析和仿真模拟，以提高设计的可靠性；根据建立起的三维模型，还可由 CAM 模块直接生成数控代码，用于产品加工。采用复合建模技术，将实体建模、曲面建模、线框建模、显示几何建模及参数化建模融为一体。参数驱动，形象直观，修改方便。 曲面设计以非均匀有理 B 样条曲线为基础，可用多种方法生成复杂曲面，功能强大。良好的二次开发环境，用户可用多种方式进行二次开发。知识驱动自动化（ KDA），便于获取和重新使nts 6 用知识。 无论是哪种 CAM 软件，其主要用途都是生成在机床上加工零件的刀具轨迹（简称刀轨）。一般来说，不能直接传输 CAM 软件内部产生的刀轨到机床上进行加工，因为各种类型的机床在物理结构和控制系统方面可能不同，由此而对 NC 程序中指令和格式的要求也可能不同。因此，刀轨数据必须经过处理以适应每种机床及其控制系统的特定要求。这种处理，在大多数 CAM 软件中叫做 “ 后处理 ” 。后处理的结果是使刀轨数据变成机床能够识别的刀轨数据，即 NC 代码。 可见，后处理必须具备两个要素：刀轨 CAM 内部产生的刀轨；后处理器 是一个包含机床及其控制系 统信息的处理程序。 UG 系统提供了一般性的后处理器程序 UG/Post，它使用 UG 内部刀轨数据作为输入，经后处理后输出机床能够识别的 NC 代码。 UG/Post 有很强的用户化能力，它能适应从非常简单到任意复杂的机床及其控制系
