The Research On Category Of Case-Based Industrial Design System

Based on the study of the state"The Tenth Five-year Plan"Key Science and Technology project-"Research on Internet-based NC Machine Tool Form Design and Humanized Interface Technologies and Implementations based on the design knowledge and user knowledge", this paper preliminary probes the state"863 Project"High Tech Research Development Project- Case Based Industrial Design Technology and Computer Aided Design System. With the analysis of the theory and experiment, I mainly made a research on the category in The Case Based Industrial Design Technology and Computer Aided Design System -CBID system.The article explained the formation and development of the category study from philosophy and psychology, 4 points of view about perceptual classifying, classifying and clustering in methodology, connection between design solution and analogism. Based on the long term study on design knowledge, the principle of NC machine tools design, and visual perception theory, plus result of NC Machine Tools Design Task Analysis and NC Machine Tools Shape Image Scale Experiments, and by the analysis of case knowledge along with case shape in CBID system, we found the case knowledge classifying regulation which is based on the engineer and designer's NC machine tools design process study, raised the case shape classifying regulation by cooperation of classical mechanical layout and key profile.According to the study on case category, by applying the cooperation of the inductive indexing method and the near-neighbor method, the system entrance and the case shape retrieval of CBID system was realized. Together, the study on case category provides the reuse, revise and retain with hierarchy basis.
