<p>PURPOSE:To increase real processing time by NC machines, and thereby control the temperature of a work piece as well as to automatically process highly precise parts by controlling process order making the waiting time of the NC machines minimum, and thereby controlling the selection of the NC machine to be used while the inputted temperature control time for the work piece is being taken into consideration. CONSTITUTION:A control device 10 to which process schedule and the like are inputted directs commands for a process program to machine tools 1 through 4 controlling carrier operation by applying a pallet member, and the carry-in/carry-out position to a pallet carrier dolly 7 has both processing time by each work piece and temperature control time required by showering at temperature control stations 5 registered as input information. The control device 10 includes a rescheduling means so as to determine a work piece to be inputted to the machine tools 1 through 4 so that the execution of temperature control over a work piece to be processed next shall be completed during processing time by the machine tools 1 through 4. And when the execution of temperature control over the work piece to be processed next is not completed even if processing of the work piece has been completed, the device is furnished with a means which selects a work piece in such a way that the waiting time of the machine tools 1 through 4 shall be minimum so that processing of the work piece is started in accordance with rescheduling.</p> |
