PLC design of NC machine tools
Abstract: With the rapid development of information industry, the functions of numerical control machine tools are maturing. CNC machine tools has been replaced by ordinary is an inevitable trend, with the development of CNC machine tools, the traditional relay control systems can not meet the industrial production needs. Programmable Logic Controller (PLC) because of its high reliability, strong anti-interference; feature strong, high cost performance; hardware package is complete, the user easy to use, adaptable; programming easy to learn and other notable features has become the first choice. In this context, this paper presents design ideas PLC CNC machine tool. This paper describes the basic composition , working principle, classification of CNC machine tools and their characteristics. And on the NC machine tool in the PLC made a detailed introduction to the work of the PLC in the process of CNC machine tools, to do a detailed analysis of the design process. Then vertical lathe C5112B, for example, describes its PLC design process, and finally introduces the PLC fault in the maintenance of CNC machine tools on some of the ways.
