This paper concerns a machine health monitoring of vibration cutting system which is one of the precision machining technology for cutting modern aviation materials or hard metals. The vibration cutting is conducted with ultrasonic vibration superimposed on the cutting tool movement. The major objective of this paper is the experimental investigation of vibration signatures to occur for the cutting speed increase or localized wear/damage on the tool edge. Our experiments show that the higher frequency vibration than the natural frequency occurs before the machining state turns worse. We hope that abnormal machining detection is possible using FFT analysis.
