Effect of Tool Posture on Chatter Vibration in Turn-milling

Abstract

Turn-milling, which is a machining method for milling a rotating work material, attracts attention as a method for cutting difficult-to-cut materials with high efficiency. However, the effect of the degree of freedom of the tool posture, which is one of its features, on the cutting condition has not been clarified. In addition, it is necessary to suppress the generation of chatter vibration in order to achieve highly efficient cutting. In this study, the effect of tool posture on chatter vibration in turn milling was investigated by both analysis and experiment.
