Variants of Mechatronic Vibration Suppression of Machine Tools

This paper deals with the investigation of different variants of mechatronic vibration suppression of machine tools. The structures of machine tools suffer from the conflict between resulting stiffness and dynamics of the machine tool. The consequence is limited accuracy and/or limited productivity of manufacturing. This problem can be solved by mechatronic modification of the machine tool instead of usual pure parametric optimization. There are several variants of such mechatronic modification for active vibration suppression of machine tools. They are the vibroabsorption by adding the auxiliary mass of vibration absorber, the vibrocompensation by adding a new parallel force connection of vibrating point to the frame, the control damping by adding a new link with damping force inside the construction and the mechatronic stiffness by adding a parallel structure to the existing one with collocated force connections between them. These variants were investigated on several examples of machine tools.
