This paper presents a compact method to predict the amplitude displacement and evaluate the influence of flexure structure on the vibration-assisted micro-milling device.The voltage load and flexure dimension variation are applied to the Finite Element model to obtain the predicted amplitude displacement. The simulation results show that amplitude displacement increases linearly along with the voltage load, but the influence of flexure thickness shows a varying trend on the amplitude displacement. The method can predict the device's amplitude displacement and movement pattern and is suitable for determining the optimum design for the vibration- assisted micro-milling device.
