Powerful expressive ability of semantic information, to be easily computed and flexibility are basic features of digital product model (DPM). Using ontology and object-oriented principle (OOP) together to cope with problems in modeling is brought forward in this paper. The two are widely used and do well in modeling, but they each alone cannot cope with all issues and new challenges. Three basic requests are pointed out in DPM modeling. Status, problems, and root of current non-semantic and semantic models are introduced. Ontology, OOP, and their difference are introduced. It is found that the two are entirely complementary with each other. How to assign the roles and to cooperate for the two in coping with the three basic issues in DPM modeling are explained in detail.

Open Cell Control System for Computer-Integrated Manufacturing

IFAC Proceedings Volumes 1997年第14期30卷 381-385页

作者： Sung-Chung Kim Kyung-Hyun Choi School of Mechanical Engineering Chungbuk National University 48 Gaeshin-Dong Cheongju Chungbuk 360-763 Korea School of Mechanical Engineering Pusan National University San 30 Jangjeon-Dong Kumjung-Ku Pusan 609-735 Korea

A Flexible manufacturing Cells (FMC) considered as a best production tool for Computer-Integrated Manufacturing (CIM) usually consists of a number of NC machines, sensor systems for the cell monitoring, robots for all par loading and unloading, and a cell controller. Most of the machines comprising an FMC are typically from different machine tool manufacturers with different communication hardware standards, protocols, and control languages. These problems lead to difficulties in integrating cell constituents and employing FMCs in a real manufacturing environment. In this study a cell controller is being developed to deal with above problems. It is designed based upon object-oriented principles, and has tow major modules: configuration and multi-layered control. Since the cell controller developed is independent of specific machine tool requirement, it allows not only operators to choose suitable machine tools for their manufacturing systems but also the machine tools innovation.
