<p>PURPOSE:To use a program data area infinitely by inputting next processing program data from a program control computer with an automatic input command and writing them in place of previous processing program data after the execution of the actual processing program is completed by an automatic operation mode. CONSTITUTION:An NC device 2-1 controls a machine tool 4-1 in accordance with actual processing program data #1 and executes the processing program. Thereafter, an automatic input command is sent via a communication line 6-1 to a program control computer 1 side with the program data of an automatic input command, next processing program data #2 inputted already to the program control computer 1 are inputted to a program data area 5-1 and next processing program data #2 are superscribed in place of the earlier processing program data #1. Thus, the limited program data area 5-1 can be infinitely used.</p> |
