PURPOSE: A numerial control device for a CNC machine tool is provided to rapidly perform a working process and to enhance the reliability of a control structure by employing an independent CPU, connecting MMI with NCK and connecting NCK with servo driving part through a high-speed communication network. CONSTITUTION: The numerial control device for the CNC machine tool comprises an MMI(Man-Machine Interface)(10) having the first CPU(12), an NCK(Numerical Control Kermel)(20) having the second CPU(23) and a servo driving part(31). The first CPU(12) of the MMI(10) performs a working program in accordance with a data and a control command which are inputted by a keyboard(13) and are related to the workpiece. Then, the CPU(12) creates working data for controlling a servo motor(41) and transmits the working data to AECNET communication module(14,21). The data related to the driving state of the servo motor(41) are displayed in CRT display(11). The second CPU(23) of the NCK(20) produces a control signal for driving the servo motor(41) in accordance with the data transmitted from the MMI(10). The servo driving part(31) operates the servo motor(41) in accordance with the control signal transmitted from the NCK(20).
