CAD/CAM integration has been an open ended problem for the factory automation. Many approaches have been followed to make the full integration, such as Computer Aided Process Planning (CAPP), and Form Feature (FF) approaches. Among other approaches those two approaches made the biggest impact however, they became shorter than the full integration. In CAPP, there are two methodologies, one is the variant and the other is the generative, which is used for the integration. In FF, a geometric feature is mapped to a manufacturing feature in a logical order.
