Nesne yönelimli yaklaşımla özellik tabanlı modelleme

Özellik-tabanlı modeller. Bilgisayar Destekli Tasarım (CAD) ve Bilgisayar Destekli Üretim (CAM)'in bütünleştirilmesinde kullanılan en iyi araçlar olmuşlardır Bu modellerde imalat işlemleri ile ilişkili olan özellikler kullanılarak tasarım gerçekleştirilir. CAD ve CAM'in bütünleştirilmesi işlemi geometri, tolerans bilgisi ve imalat ile ilişkili veriyi içeren çeşitli veri tiplerinin bütünleşme kapasitesine sahip geniş bir bilgi yapısı gerektirir. CAD ve CAM'i içine atan yoğun uygulamalarda nesne-yönelimli modelleme yaklaşımı, tasarımda ve oluşturulan verinin uygulanmasında son yıllarda önem kazanmıştır. Nesne-yönelim düşüncesi, büyük ve geniş veri ağacı hiyerarşilerine ayrıştırılarak bu sistemlerin karmaşıklığının giderilmesi ve belirginleşmesi için çok iyi bir araç sağlar. Bu çalışmada nesne-yönelimli veri tabanı yapısı kullanılarak oluşturulan özellik tabanlı bütünleşik CAD/CAM sistemlerinin modellenmesi incelenmiştir, önerilen nesne-yönelimli model, sistem tarafından istenen veri bütünlüğünü ve veri soyutlanmasını destekler.

Feature-based modals have been the best tools lor integrating Computer Aided design (CAD) and Computer Aided Manufacturing(CAM). These models enable design using the properties related to production processes. The integration of CAD and CAM requires a wide information structure comprising data on geometry, tolerance and manufacturing. Feature based modeling approach to intense applications involving CAD and CAM, has recently gained importance for design and application purposes. Object-oriented thought decomposed into a large and wide data tree hierarchy provides a very useful tool for simplifying and crystallizing these systems. This study investigates modeling of property based integrated CAD/CAM systems using the objectoriented database structure. The proposed object-oriented model supports the data integrity and abstraction required by the system.
