Mode coupling chatter suppression for robotic machining using semi-active magnetorheological elastomers absorber

Chatter is one of the major barriers for robotic machining process. As the dominant vibration frequency of the chatter varies under different working conditions, Magnetorheological elastomers (MREs) whose stiffness is adjustable is an ideal device to be used for chatter control. This paper presents a new mode coupling chatter reduction scheme by assembling an MRE absorber on the spindle to absorb vibration with a specific frequency range....
