Open CNC System Based on Embedded Monitoring Unit


Article Preview

Regarding to the requirement of machine tool state monitoring in the functional diversity of CNC system, the prototype of an open CNC system based on embedded monitoring unit is studied and constructed. According to the analyzing of the development status of machine tool state monitoring, an embedded monitoring unit model, which connects with the CNC system through the field bus and can be reconfigured when the monitoring target changed, is set up with the ARM + DSP master-slave architecture, through which the state of machine tools can be accessed by the CNC system. In view of the development trend of open CNC system, a four-layer open architecture reference model is proposed, which will meet the demand for structure adjustment and function expansion. In addition, the key supporting technologies in the system design are also researched, so as to provide a feasible solution for the maintenance and multifunction integration of CNC equipment.
