| Abstract | ||
| This paper introduces Developed Attributes Adjacency Matrix (DAAM) approach for extracting and recognizing of part’s features, by deal with decoupling or isolated manufacturing features. The proposed algorithm consists of two stages, pre-processor stage which perform extraction of information from Design Exchange Format (DXF) file format in Computer Aided Design (CAD), and postprocessor stage which recognizes part’s features depending on attributes adjacency matrix. The main contributions of this research include building the adjacent relations between faces of the part by geometrical characteristics in form of matrix, and use clustering operation to extract the exact faces of feature and use different classes of geometrical characteristics to assisting to recognize depression prismatic features useful in machining and other application such as dimensional inspection and assembly. | ||
