4.2 CAD/CAM实例研究及FMS工件程序的数据结构本节讨论应用三维图形系统设计一个箱形部件,引导读者通过设计过程的十五个步骤。在着重制图技术的讨论中,我们也指出CAD系统具有代表性的缺点,帮助这种系统的用户和设计者相互更加了解。设计和生产的集成带来惊人的节约。但是,遗憾的是很少可供使用的系统能提供具有正确合理的而且是高水平的解答。CAD/CAM实例研究,并有编程示例。关于CAD系统的优点已经发表了很多文献,我们着重讨论某些给工程师和数据处理专家带来困难的问题和缺点。在购置
4.2 CAD / CAM CASE STUDY AND DATA STRUCTURE OF FMS WORKPIECE PROGRAMS This section discusses the design of a box-shaped component using a three-dimensional graphics system to guide the reader through the fifteen steps of the design process. In the discussion of mapping technology, we also pointed out the disadvantages of CAD system to help users and designers of this system know each other better. The combination of design and production brings amazing savings. However, it is a pity that very few systems are available to provide solutions that are correct, but high-level. CAD / CAM examples of research, and programming examples. Advantages of the CAD system A lot of literature has been published, and we focus on some of the problems and disadvantages that make it difficult for engineers and data-processing specialists.
