Chatter vibration in cutting induces tool damage, large machining error, and deterioration of surface finish. The cutting conditions should be determined for the stable cutting process. The vibration analysis requires the modal parameters in the vibration model. Therefore, the modal parameters should be identified to predict the stability chart. In milling, the modal parameters might change corresponding to the tool-workpiece contact depending on the cutting thickness during a ration of the cutter. This study discusses the change in the modal parameters in milling. The impulse response tests were conducted with measuring the cutting force. The changes in the modal parameters were compared for the feed rates and the feed directions.
