概要

• 論文の詳細を見る

• 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.
