Title:
APPARATUS AND METHOD FOR CONTROLLING RESONANCE SUPPRESSION OF MACHINE TOOL
Document Type and Number:
WIPO Patent Application WO/2020/045975
Kind Code:
A1
Abstract:
An apparatus for controlling resonance suppression of a machine tool according to the present invention, comprises: a numerical control part; a main operation part; a PLC for executing a control command by means of communication with the numerical control part or the main operation part; a servo drive for executing the control command of the PLC; a servo motor part driven under the control of the servo drive; and a power conversion part for applying electric energy to the servo motor part by being electrically connected to the servo motor part and the servo drive, wherein the power conversion part adjusts the electric energy applied to the servo motor part according to a signal from the servo drive so as to control resonance suppression according to the operation of the servo motor part.
