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.
