The modern production machinery uses the control technology which the machinery, the electricity, the hydraulic pressure, air operated unify. The electric control technology plays the joint main center role, the application is most widespread. Out of the ordinary machining prevalence of poor quality products, variety of small, low grade, high cost, delivery and long, so this design object is an ordinary lathe, designed a comprehensive and efficient PLC control system, improved lathe productivity, control accuracy and product quality. PLC (programmable controller) as an industrial control micro-computer, with its easy programming, simple operation, especially its high controllability, etc., in the industrial production process has been widely used. The PLC control system design is to replace traditional Relay - contact device control system. The article first introduces the lathe, and electrical control systems, PLC control system and then introduces the hardware structure, operation principle and design of the basic principles of PLC control systems and procedures, according to the task to design a PLC control system, including the PLC elections type, hardware design and software design. Finally, Siemens touch screen TP177B connected devices, monitoring and control oper
