A Study on Intelligent CIM Systems

本研究项目的成果总结如下。(1)CIM系统的概念收集和分析使用个人计算机。我们将各种CIM概念分为五个级别。此外，还对日本和国外开发的CIM系统进行了调查。(2)研究了CIM系统中数据库的对象表示模式。讨论了目前在设计和制造领域的一些方案。然后，我们提出了一个集成的表示方案的基础上的状态的概念。(3)提出了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，它表明，在早期设计阶段的设计对象的要求可以组织为产品数据的建模系统。(4)结合一个产品（零件）加工群，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生成运动函数的最小集合成为可能。(5)由面创成运动函数导出机床基本构形的一种方法。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)提出了一种从手绘图中提取产品信息的方法，作为一种灵活的人机接口，并给出了原型。(7)提出了一种根据最终产品数据设计原材料形状的方法。它的系统是用购买的工作站实现的。正如你上面看到的，计划的研究主题被认为是执行。再加上这些结果，有必要继续进行这项研究项目。

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.
