This article in the analysis modern commonly used three milling machine aggregate machine-tool control system's foundation, proposed one kind (PLC) takes the master control design proposal based on the programmable controller, and has completed the hardware and the software design. This control system has the stability to be high, the compatibility is strong, the cost low status merit, after the simulation debugging, meets the work requirement completely.
key word: Three facing set aggregate machine-tool PLC control system software design
