Abstract :Computer Aided Process Planning insert ignore into journalissuearticles values(CAPP); plays an   important role in the development of Computer Integrated Manufacturing systems insert ignore into journalissuearticles values(CIM); and provides a vital link   between Computer Aided Design insert ignore into journalissuearticles values(CAD); and Computer Aided Manufacturing insert ignore into journalissuearticles values(CAM);. Automatic extraction and recognition of part features directly from a CAD database also strengthen the link between CAD and CAPP. In this study, an automatic feature recognition and CNC code generation insert ignore into journalissuearticles values(AFR/ACCG); system   was developed for rotational parts. This system was prepared using Delphi 7 programming language. The data input to the system is done by DXF insert ignore into journalissuearticles values(Drawing Interchange Format); prepared in any CAD programme. CNC part programme of the work piece to be produced is generated automatically as to machining features in this system. Sample parts were machined by the generated tool paths and part geometries were obtained accurately. All of the internal and external machining features of complex parts such as grooving, threading and boring can be defined automatically using this system by the nine determined elements.   Keywords: CAD/CAM, CAPP, AFR, Automatic CNC code generation
