NC programming for multi-tasking machine tools requires much time and labor. The study proposes the rationalization of the process planning by extracting the machining feature in consideration with turning and milling from targeted complex shapes to be machined and by both selecting the suitable machining method and arranging the machining order automatically. As a result, it is expected to reduce the preparatory time on CAM system, using output data from the proposed system. Applying the system to several product shapes containing both turning feature and milling feature, it is confirmed that NC data can be obtained for each shape without any problem.
