<p>This invention relates to a numeric control unit for a multiple-spindle and multiple-system machine tool wherein a plurality of spindles are controlled by a plurality of systems. A main processor (1) for executing data processing other than those of a servo system and an operator interface module (2) are connected to a first bus (7). A plurality of servo command generation processors (10, 20, 30) for generating input data processing and servo commands for each channel are connected to the first bus (7) and to a second bus (41). A plurality of servo control processors (42 to 45) are connected to the second bus (41) and transfers only the servo command data. The first bus (7) transfers the data other than those described above. In this manner, the generation of the servo commands can be processed at a high speed and a high-speed control of a multiple-spindle and multiple-system machine tool can be accomplished.</p> |
