D16 Detection of chatter by the measurement of acceleration of the spindle head in the axial direction(Monitoring of machining process)
Details
The acceleration of the spindle in the axial direction was measured when preharden steel was slotted with a square end mill under several cutting conditions. The signal of the accelerometer was stored and processed through digital Fourier transformation on a personal computer. The power spectra had peaks in a distinctive frequency range when chatter occurred. There is a threshold value of the ratio of the maximum intensity in the range to the one at the frequency of interrupted cutting by edges for detection of chatter.
