<p><P>PROBLEM TO BE SOLVED: To provide a laser beam machine which, when there is a non-executable schedule during scheduled operation, leaves it until later, carries out an executable schedule first from that point forward, and subsequently tries executing the non-executable schedule again. <P>SOLUTION: The laser beam machine includes: a stocker 1 in which a plurality of pallets P for holding workpieces W are stored in multi-stage; and a machining station 4 in which a pallet machining part 41 is provided for the purpose of placing the pallets P to perform laser beam machining on the workpieces W. The machine takes out the pallets P one by one from the stocker 1 to transport the pallet to the machining station 4 for laser beam machining in accordance with a schedule list stored in a storage device. The machine also includes: a checking means which confirms whether the pallets P to be used can be machined in the schedule to be executed; and a swapping means which, when the pallets P to be used can not be machined, leaves it until later in the execution sequence of the schedule list. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
