Abstract
The paper presents a simple but effective method to detect and suppress chatter in drilling operations. Unlike conventional approaches, complex cutting dynamics in drilling operations do not need to model and analyze in this new approach. Chatter is detected when a large thrust force or torque variation is observed. Then, a simple spindle speed change method using the chatter frequency to guide the modification of spindle speed for suppression of chatter is applied. It is shown, by experimental results, that chatter in drilling can be effectively suppressed by using this method.
