GAO, J. and CASE, K., 1991. Process capability modelling: a review report of feature representation methodologies. IN: Proceedings of the Symposium on Feature-based Approaches to Design and Process Planning, Loughborough University, September 1991.
Approximately 150 technical papers on the features methodology have been carefully studied and some selected
papers have been commented upon. The abstracts of the comments are documented and attached to this report. The
methodologies reviewed are mainly divided into two approaches, ie. feature recognition and design by features.
Papers which deal with some specific topics such as feature taxonomies, dimensions and tolerances, feature
concepts, etc. are also included in the document.
