Fault detection methods and experimental system of high-grade CNC machine tool wear

To build fault diagnosis system of CNC machine tools and get test method,tool wear experiments are carried out.Signals for cutting tool with different wearing degrees in milling process are detected and analyzed through vibration sensors and acoustic emission sensors on the milling tools.Using LabVIEW8.6 as development platform,a fault diagnosis experimental system of CNC machine tools is developed,including data acquisition module,signal analysis module and fault diagnosis module.
