PROBLEM TO BE SOLVED: To analyze and correct NC data and machining schedule data in order to heighten the efficiency of die machining setup.;SOLUTION: A processing part 9 reads a plurality of NC data and machining schedule from an NC data memory. Subsequently, data on dies arranged in a turret disk in the current state is read from a die arrangement data memory 21. A schedule draw-up part 13 draws up a machining schedule taking into consideration the high efficiency of die setup with priority to the schedule by selecting a schedule priority part 15 or a die arrangement priority part 17, or draws up machining schedule data taking into consideration the high efficiency of die setup with priority to die arrangement. The schedule data is stored in a machining schedule data memory 23. An NC turret punch press reads the machining schedule data through a communication system 7 to perform actual sheet metal product machining.;COPYRIGHT: (C)2003,JPO
