BİLGİSAYAR DESTEKLİ PARÇA TANIMA SİSTEMİNİN GELİŞTİRİLMESİ VE MOTOR MONTAJINA UYGULANMASI.

In this study, an approach has been developed to recognise the parts of a diesel engine using their face adjacency relations and attributes and to assembly the recognised parts in a computer aided design (CAD) environment. An expert system technique has been used in recognition procedures. CAD models of the parts of the engine are automatically translated into their STEP files and neighbouring faces and face attributes of each face on a part are extracted by evaluating of the generated STEP file. A database is also constructed using a text editor. Comparing the face adjacency relations and the attributes in the database and part recognition procedures, the parts are recognised by the computer. The part model is saved into the database with the name of the part and is represented in its face adjecency relation matrix. In the assembly stage, reference surfaces of the recognised parts are determined and they are assembled by moving into the assembly file through the reference surfaces in a CAD environment.
