Features technology: an integration methodology for CAD and CAM

Genuine integration of Computer Aided Design (CAD) and Computer Aided Manufacture (CAM) is becoming ever more urgent within the wider context of a total Computer Integrated Manufacturing environment. In seeking this integration it is recognised that the diversity of activities and consequent needs for data can best be served by a single representation for all aspects of the product life cycle, including design, design analysis and manufacturing planning. The strongest candidate for this descriptive role is a Feature Representation, and this paper reviews feature technology and the use of features through Feature Recognition and Design by Features. An attempt is also made to identify future areas of research.
