Abstract

An active vibration-suppressed workholding platform (AVSWP) for milling machines is proposed. As to metal cutting, vibration is one of the major factors which affect the surface roughness of finished workpieces. Once the excessive vibration is present during milling process, the surface roughness of the workpiece would be accordingly downgraded. Therefore, AVSWP is proposed to actively suppress the vibration induced by the cutting force. To achieve this goal, an active noise feedback controller based on FxLMS (Filtered-x Least Mean Square) algorithm is applied to achieve satisfactory performance in terms of vibration suppression. According to the experimental results, the vibration of workpiece during milling process can be effectively suppressed by 55% compared with the open-loop case. Besides, from the realistically finished workpieces, it can be observed that the quality of machined surface is upgraded, owing to the vibration of workpiece being successfully suppressed by AVSWP.
