| Abstract: | Based on a computer numerical controlled(CNC) machine tool,some dynamic experiments are done for finding out the main dynamic milling vibration.At first,the frequency response curve of relative vibration between cutter and workpiece is obtained from the cutting experiment.Then the experimental modal analysis and milling test are done to find out the mode shapes and frequency of the tool.From the contrast,the main frequency of milling vibration is found. |
