<p>PURPOSE:To attain rapid and highly accurate control economically by transferring a large part of the functions of an NC part formed on the machine side to the computer center side having a computer of large capacity which can be rapidly accessed. CONSTITUTION:The steady control of a machine M1 to be controlled is executed on the basis of NC control data supplied from a computer center CC arranged on a position other than the position of the machine M1 to an NC control part of a machine M through an operation stage, machine performance data and servo control data. A speed or acceleration pattern of the machine M1 is picked up by the center CC side on the basis of a monitoring periodically e.g. generated from the center CC to inspect the performance of the machine at its working. When an operation value meaning the generation of abnormality in the working of the machine M1 is detected in a speed or acceleration operation part M5, the operation part M5 supplies an alarm signal to the center CC side, and while waiting a command for the corresponding process, operates so that the command is supplied from the center CC side.</p> |
