工作機械用軽量化ステージにおける制御手法の検討

抄録

In terms of high speed and high precision as well as energy saving, development of lightweight machine tools applying new structural materials such as CFRP is under consideration. When the weight of the machine tools is reduced, on the other hand, the position response of the table is more sensitive to disturbance force including cutting force. In this case, it is difficult to ignore the influence of mass reduction of the workpiece by cutting, which demand control strategies to play a greater role. In this study, a robust control method for lightweight driving element was considered. By constructing acceleration control system that had disturbance compensation function, it was confirmed by numerical simulation that the influence of mass variation could be reduced.
