<p>This invention relates to a numerical control device for transfer machines that control multiple transfer machines installed in a transfer line. The numerical control device is comprised of an NC part (13) that controls the spindles of the transfer machines, and a PMC part (14) that executes sequence control. The PMC part (14) reads the current position data from a current position register (16) through a window for comparison operation with a pre-set area data (19). A functional instruction (18a) executes the alteration control of the execution sequence using the operation result as an area signal, thereby setting of a highly accurate area signal is made possible.</p> |
