<p>A numerical control unit having: a main memory (3) for storing numerical control programs and the like, a main processor (1) for executing the data processing necessary for numerical control, and a main bus (2). In the unit, local buses (4a,4b) are coupled to the main bus (2) through buffer circuits (5a,5b), respectively, with respect to control axes, and axis-control circuits (8a,8b) are coupled to the local buses (4a,4b), respectively. In addition, coupled to the local buses are local processor units (6a,7a;6b,7b) for taking a part of the loading to the main processor (1), as required, according to the number of the processings in the main processor.</p> |
