Abstract
Whenever chatter appears in the process of manufacturing material by spindle and machine tool, abnormal noise and vibration signal necessarily occur. This has a significant correlation to a variety of faults. The chatter diagnosis method through the vibration signal processed is proposed. Changing cutting condition such as cutting rotating speed and depth, the signal of chatter occurrence is measured by using accelerometer sensor. When chatter appears, the frequency response of vibration signal is composed of harmonic tonal components by spindle rotation and others tonal components. Using this property, index that represents characteristic chatter signal is composed of processed frequency response of the signal with Moving average filter, and envelope using Hilbert-transform.
