<p>A numerical control unit for a machine tool comprising a transmitter circuit (43) provided in a numerical control section, for feeding each block of working information to an abnormality-monitoring section (6), and a receiving circuit (61) for receiving each of the blocks of working information and a block-content-decoding circuit (63), which are provided in the abnormality-monitoring section (6). Thus, as the working proceeds, the content of the block and a block-execution-end signal are fed from the numerical control section (4) to the abnormality-monitoring section (6) block by block, so that the abnormality-monitoring section (6) decodes the contents of each block.</p> |
