خلاصه مقاله:
An analytical approach for prediction of chatter in milling process is presented. Existing approaches use lumped parameter models to define the dynamics of the tool/work-piece. In this paper a continuous beam model is employed for prediction of milling operations dynamics. The tool boundary conditions are assumed elastic support at the tool/holder/spindle interface and free at the other end. Employing a continuous model eliminates the need for tool tip FRF measurements in tool tuning practice. Using the new analytical approach stability lobes are obtained for a slotting operation.
