For shortening of production lead-time, it is needed to eliminate time and efforts for process and operation planning after product design. However, a conventional NC machine tool has no autonomy and intelligence to achieve direct machining operation or “Rapid Manufacturing”. Because CL data and cutting parameters for machining operation have to be determined precisely in process and operation planning. In this study, in order to realize an autonomous and intelligent machine tool, the digital copy milling system which allows to generate tool paths during machining operation, and the trouble free machining strategy which allows to adapt cutting parameters, have been developed. And, an automatic process and operation planning system has been developed to integrate with the functions mentioned. This planning system works on commercial CAD software, and a prototype of autonomous and intelligent machine tool can achieve direct machining operation or “Rapid Manufacturing” which does not require any effort to prepare an NC program.
