| Abstract: | The chatter phenomenon and low efficiency in the milling process of aerial aluminum alloy thin-wall part are studied from the dynamics aspect. A combination method of process optimization to hold high process system stiffness with milling dynamics simulation is presented.Test results prove that better effect is gained by using this method,and the chatter problem of aerial aluminum alloy thin-wall part is solved.The surface quality of workpiece and machining efficiency are improved. |
