Abstract: Computer-aided process planning (CAPP) is an essential interface for linking design and manufacturing processes. The purpose of CAPP is to transform a part design specification obtained from CAD system into a sequence of machining operations which can be used by CAM system involving the selection of necessary manufacturing processes, in order to transform a designed part into a final part economically and competitively. This paper focuses on one hand, in the extraction of tolerances (GD T), and on the other hand, in the association between (GD T), and the related features, embedded into an expert CAPP system.
