Özet:

In this paper, a new part description format named face oriented relation matrix for part recognition approach has been developed. The matrix developed defines the parts in terms of both geometric and topological (face connectivity relations) data. In the matrix, face connectivity relations belonging to the part along with attributes belonging to all the faces on the part are explicitly represented. STEP file of the part designed in a CAD environment is used to construct the matrix as input. On the contrary the part description schemes commonly used in the literature, the part representation format was both simplified and structured suitable to computer format by the face oriented relation matrix developed. To demonstrate the efficiency of part description scheme, the method was implemented to standard machine parts and parts of a diesel automobile engine
