Logic level of workpiece object database oriented on manufacturing features

Abstract

Manufacturing features are widely accepted as a means for the integration of CAD/CAPP/CAM systems. Despite high number of works in this area, the investigations on the logic structure of the databases used for the storage and processing of manufacturing features are very limited. The paper presents the logic level of the object database oriented on manufacturing features. This level consists of four layers: topics, structures, attributes and methods. Each of these layers is discussed and illustrated with the examples taken from the workpiece modeling subsystem of rotational parts with non-rotational features.

Application of Knowledge Based Systems in Technical Preparation of Machine Parts Production

“…Therefore, the knowledge system proposed by [1] can help in identifying of potential manufacturing problems early in design stage and in determining of machining precedence constraints (hard constraints) in situation of feature volumetric interaction, [2] presents the logic level of the object database oriented on manufacturing features.…”
