A Study on Intelligent CIM Systems

本课题的研究成果总结如下。(1)使用个人计算机收集和分析CIM系统概念。我们将不同的CIM概念分为五个层次。此外，还对日本和国外发展的CIM系统进行了调研。(2)研究了CIM系统中数据库的对象表示模式。我们讨论了目前设计和制造领域中的一些模式。在此基础上，提出了一种基于状态概念的综合表示方案。(3)提出将计算机辅助概念设计系统的概念作为CIM系统的信息源。使用购买的工作站开发了一个实验系统，并证明了在建模系统中可以将早期设计阶段对设计对象的需求组织为产品数据。(4)针对一组加工产品(零件)，提出了一种机床运动功能的解析设计方法。这种设计方法使得确定面展成运动函数的最小集合成为可能。(5)由面生成运动学函数推导机床基本构型的方法。此外，还收集和分析了与机床设计相关的设计知识。在此基础上，实现了机床基本构型设计系统，并对设计方法进行了评价。(6)提出了一种基于手绘图形的产品信息建模方法，实现了灵活的人机界面，并给出了原型系统。(7)提出了一种从最终产品数据设计原材料形状的方法。它的系统是使用购买的工作站实现的。如上所述，计划的研究对象被认为是正在进行的。除了这些结果，有必要使这项研究项目继续下去。

The results of this research project are summarized as followings. (1) CIM system concepts were collected and analyzed with using a personal computer. We have categorized various CIM concepts into five levels. Furthermore, survey on CIM systems developed in Japan and foreign countries was executed. (2) We studied object presentation schemata for database in CIM systems. We discussed about some present schemata in the field of design and manufacturing. Then, we proposed an integrated presentation scheme based on the state concept. (3) The concept of a computer aided conceptual design system is a proposed as the information source in CIM systems. A experimental system was developed with using the purchased workstations, and it was demonstrated that the requirement for a design object at the early design stage could be organized as product data in the modelling system. (4) With related to a machining group of products (parts), an analytical design method of the machine tool's kinematic function was proposed. This design method makes it possible to decide the minimum set of face-generative kinematic function. (5) A method which derive the basic configuration of machine tools from face-generative kinematic function. Furthermore, Design knowledge about designing machine tools was collected and analyzed. Based on this result, a design system for the basic configuration of machine tools were implemented, and the design method were estimated. (6) A method for modelling product information from hand-drawings was developed as a flexible man-machine interface, and a prototype was lamented. (7) A method for designing shapes of raw material from final product data was developed. A system for it was implemented with using purchased workstations.As you see above, planned research subjects are considered to be performed . Adding to these results, it is necessary to make this research project continued.
