摘要： 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.

摘要： A numerical controller having a main processor (1) for NC control and a plurality of subprocessors (61a, 61b) for servo control provided to meet the number of the controlled shafts. Between the main processor (1) and the subprocessors (61a, 61b), there are provided LSIs which contain shared RAMs (91a, 91b) for data exchange and arbitration circuits (94a, 94b), respectively. These LSIs (9a, 9b) are provided for their respective subprocessors (61a, 61b), and they act between the main processor (1) and the corresponding subprocessor (61a) only. Further, since the circuit that includes the LSI (9a, 9b) and the corresponding subprocessor (61a, 61b) for servo control is constituted as an independent module, the numerical controller can be easily realized to control an increased number of shafts by simply increasing the modules depending upon the number of shafts to be controlled.
摘要翻译：数字控制单元包括用于NC控制的主处理器（1）和用于伺服控制的多个子处理器（61a，61b），以响应被控制的树的数量。在主处理器（1）和子处理器（61a，61b）之间，存在大规模集成系统，其包含用于数据交换电路的公共RAM（91a，91b）和仲裁电路（94a，94b）。这些大规模集成系统（9A，9B）被提供用于相应的子处理器（61A，61B），并且它们只作用在主处理器（1）和相应的子处理器之间（61A，61B）。另一方面，由于包括用于伺服控制的大规模集成系统（9a，9b）和相应的子处理器（61a，61b）的电路被构成为独立模块，数字控制单元只需通过根据要控制的树木数量增加模块的数量，就可以轻松设计出来控制树木数量的增加。
