Application And Research Of PLC In Machine Tool Numerical Control System

With the development of electron and communication, the technology sustain have provided for our machine tool equipment modernization. More and more financing and technology are plough into the tradition machine for exerting efficiency and prompting precision rapidly, acquire well impression. Now it become efficiency approach for corporation reconstructive , by numeric control system composing PLC module frequency and conversion control and inspect equipment carry out programme import and automatization control, to reduce trouble and improve efficiency.The paper summarize the design project and application technology in machine numeric control system, and introduce the PLC development and application in simply ,by the machine numeric control system reconstructive.The paper introduce the PLC programme specialty and mode , emphases the STEP 7- Micro/Win V4.0 design project and application technology for example SEIMENS S7-226 PLC.And the paper introduces the PLC interface technology and the HMI, in the freedom mode of PCL and PC message theory technology.Finally, the paper summarized research achievement,discussed soft resue technic in research subject combine with author's specialty,prospected the further study in the future.
