CNC SYSTEM FOR CONTROLLING A PLURALITY OF MACHINES |
摘要 |
<p>A main central processing unit (CPU) and a plurality of CNC units each corresponding to each of machine tools are connected to each other through a bus line, and the main CPU is connected to an external storage device and an external input device. To change the operational control of a machine tool and the processing data for a workpiece, a new system program is downloaded to a CPU for a CNC unit from the external storage device through the RAM of the main CPU, and normally, a PERT program including the processing data stored in the CPU for the CNC unit is changed. <IMAGE></p> |
