Surface texture formation by non-resonant vibration assisted micro milling

Abstract

This paper proposes a new surface texture formation method by non-resonant vibration assisted milling. Firstly, the kinematics of the vibration assisted milling process is formulated and surface texture formation in end milling with different machining and vibration parameters is discussed. Various types of surface textures can be generated by different combinations of machining and vibration parameters. Secondly, a novel 2D non-resonant vibration stage is developed to realize the vibration during the milling process. Thirdly, vibration assisted milling experiments are carried out to verify the proposed surface texture formation method and the effects of the vibration and machining parameters on the surface texture generation. Finally, hydrophilic performance of the machined surfaces with different surface textures is investigated to demonstrate the application of the proposed method.
