A new method for chatter detection in turning on a lathe is introduced. It exploits a signiicant change of cutting dynamics caused by the onset of chatter. The changes are reeected in both dynamical and statistical characteristics. Experimentally, the transition from chatter-free cutting to chatter was achieved by a change of either cutting depth or turning… CONTINUE READING
