<p>A numerically controlled apparatus constructed to comprise: a sampling means for sampling the block ending information of each system program; a means for specifying a resuming block and a resuming position of each system at a working interrupting time on the basis of the block ending information of each system; and a means for resuming and starting each system, by computing the synchronous relation information among the individual systems from the block ending information of the systems when the working is resumed at the resuming positions, on the basis of the computed result. With this construction, even the numerically controlled apparatus handling multiple systems can restore the synchronous relation among the systems to resume the working.</p> |
