LITERATURE REVIEW OF OPTIMIZATION TECHNIQUES FOR CHATTER SUPPRESSION IN MACHINING [PDF]

open access: yesJournal of Mechanical Engineering and Sciences, 2011
Chatter produces a poor surface finish, high tool wear, and can even damage machine tools because of the regenerative effect, the loss of contact effect, and the mode coupling effect. Various research works have investigated the suppression of chatter by

Proposal of novel spindle speed variation profile with constant acceleration rate for improvement of chatter stability [PDF]

open access: yes, 2021
Spindle speed variation (SSV) is one of the effective methods which suppresses regenerative chatter. However, regenerative chatter can grow even if SSV is applied. In the previous work, the chatter growth characteristics in SSV were clarified.

The countermeasure against forced and regenerative chatter in end milling process with multiple dynamic absorbers

open access: yesNihon Kikai Gakkai ronbunshu, 2014
The present study investigates the effect of multiple dynamic absorbers on both forced chatter and regenerative chatter. The stability lobe of regenerative chatter is widely employed to find the axial depth of cut and the spindle speed in which ...
