<p>PURPOSE:To provide a control device for a numerically controlled machine tool group wherein a workpiece of completing its machining can be prevented from staying for a long period in a line though inputting workpieces is given top priority. CONSTITUTION:A workpiece is inputted in accordance with order of inputting a production data (step 110). However, when a workpiece input in accordance with the inputting order can not be performed unless the input passes the inputting order ahead by a permissible number or more (judge step 106 is No), the workpiece, not generating for a while its return in accordance with the inputting order, (final workpiece) of pallets of completing machining is selected to be returned to a loading station LS, to remove the workpiece of completing machining (step 107). The pallet, not generating for a while its return in accordance with the inputting order, of the pallets of completing machining is selected by confirming that the workpiece, mounted on the machining completed pallet of select judging object, is not in agreement with the workpiece expected to be inputted in accordance with the inputting order.</p> |
