Mode-dependent Chatter Stability in Micro Milling: Structural Modeling and Experiments
Due to high excitation frequencies and flexible micro end mills, the chatter frequencies are usually much higher in micro milling than those in conventional milling and associated with the dominant modes of the machine tool system. This paper presents the structural modeling of a spindle system applied to micro milling with finite elements. The variation of the clamping conditions at the tool holder is also taken into account, which significantly affects the dominant modes of the system. Using piezo actuators, chatter frequencies can be fast identified without extensively repeating the operations at different depths of cut.
