Development of high tooling technology using object oriented tool database

为了提高柔性自动化制造系统中刀具的使用效率，刀具数据库必须支持刀具生命周期的整个领域中使用的信息。本文的主要研究成果如下：1）采用过程描述方法IDEF 0对刀具寿命周期支持活动中的刀具使用进行了描述，明确了刀具使用所需的信息及其相互关系; 2）采用数据规范语言EXPRESS对刀具使用所需的刀具数据模型进行了描述; 3）阐述了在面向对象的数据库管理系统中实现刀具数据库的过程。

To increase the efficiency of the tool use in a flexible automated manufacturing system, it is necessary for the tool database to support information used in the whole field of the tool life cycle. A management system sharing with some tools in some machine tools and using them, can make the best use of tool capacity.The conclusions of our research can be summarzed as follows :1)The tool use in the Tool Life Cycle Support Activity was represented using process description method IDEF0, and the necessary information and relationships among pieces of the information were clarified.2)The tool data model needed for tool use was represented in data specification language EXPRESS.3)The procedure to implement the tool database in the object oriented database management system was explainded and preformed.
