Document Type and Number:
Japanese Patent JP2704900
Kind Code:
B2
Abstract:
PURPOSE:To facilitate the management of power sources by transferring all unprocessed workpieces relating to processes which should be carried out beforehand, to machine tools when a power source cut-off instruction on a processing schedule is executed, and by processing the workpieces. CONSTITUTION:When a power source cut-off instruction POC on a processing schedule MSC stored in a memory device is executed, A schedule control section 13 which controls a machine tool facility in accordance with the processing schedule MSC, transfers unprocessed workpieces having a workpiece number WNO and relating to processes which should be carried out before the execution of the instruction POC to machine tools 5A through 5C so as to process the workpieces. After completion of the processes, when the time of power source cut-off set on a timer 22 has come, power sources for the machine tools 5A through 5C are respectively cut off through the intermediary of AND circuits 25 through 27 and a power source control section 29. Thus, it is possible to cut off the power sources in such a condition that the operation is readily restarted.
