Machining Monitoring and Database System Based on PLC and Kingview

Four convex surfaces distributed along the circumference of cylinder parts need to be milled. Restricted by the processing way, sometimes the workpiece is not finished in this process after it is removed from the machine tool, which may influence the subsequent process. A monitoring system based on S7-200PLC and Kingview is designed in order to achieve two effects: firstly, this system can give an alarm when the workpiece is removed from machine tool if it is not finished; secondly, this system can set up a database and save processing information. The application result is analyzed.
