Feasibility Study on Milling Chatter Suppression in Viscous Fluid
摘要
Abstract
During the machining process, chatter is the key factor to limit productivity. In the present study, experimental investigations are concerned which assess the feasibility by submerging the milling system in viscous fluid to mitigate milling chatter. Higher stability limit is obtained with the proposed approach, which indicates that the milling efficiency can be improved greatly under viscous fluid condition. The stability improvement can be attributed to the variations of the milling system dynamic characteristics and cutting force coefficients. Due to the extra energy loss, the damping of the milling system increases significantly under viscous fluid condition. Additionally, the cutting force coefficients are calibrated and the results indicate that the cutting force coefficients reduce significantly under viscous fluid condition by compared with the dry milling. The explanations are verified by the experiments, which validate the effectiveness of the proposed approach on the suppression of milling chatter.关键词
