Paper Abstract

Chatter suppression in milling machines, using acoustic signals, is examined for preventing poor finishes and for upgrading production quality. The technique of on-line acoustic signal analysis for suppressing chatter has been examined in realistic milling experiments. The natural frequency was determined for end mills, based on finite element analysis, so that beam equations could be used for chatter detection. Frequency domain analysis was employed to monitor the shift in the dominant frequency. In this study, the acoustic chatter signal frequency and resonant peak were applied using a feedback control loop to quantify the acoustic signal and to compensate for spindle speed, respectively.
