Abstract: Vibrations are one of the most important aspects in the dynamic stability considerations, especially in high speed machining. In this case, analysis and monitoring of the vibrations in Computer Numerical Control machine (CNC) spindles are of great concern for fault detection and implementing condition based maintenance. In this context, a study on vibration analysis of the CNC machine spindle is carried out by acquiring and analyzing the vibration signals, thereby the tool wear can be predicted. A single axis piezo-electric accelerometer is used to detect the vibration signals and Laboratory Virtual Instrument Engineering Workbench (LabVIEW), a graphical programming language, is used for acquiring and analyzing the signals. A graphical user interface was developed to represent the condition monitoring in a very effective way. The LabVIEW based condition monitoring system was found to be easier and accurate.
