Abstract

Knowledge representation and expert system based operation selection in a process planning and fixturing system M. Giilesin & R.M. Jones Coventry University, School of Engineering, Priory Street, Coventry CV1 5FB, UK ABSTRACT Process Planning is the prime interface between CAD and CAM systems. At Coventry University an Intelligent Knowledge Based Process Planning for prismatic parts has been developed. The system, called EPPSU, is able to produce process plans automatically. This paper introduces the knowledge representation within the system and describes the notation for representing knowledge. The structure of the knowledge base developed for operation selection is overviewed and one specific subset area in process planning namely selection of processes is presented. 1. INTRODUCTION CAD and CAM systems have increased productivity, reduced overall costs and offered more flexibility in industry. Nonetheless, the integration of such two systems has not
