Abstract
AUVAM is a theoretically promising method for manufacture of complex micro-textures on the workpiece surface due to its low cost and high efficiency. However, due to the generation mechanism of AUVAM processing is indeterminacy, it is difficult to reproduce the ultrasonic amplitude completely. In this paper, the influence of the end cutting edge angle on empty cutting and interference is found to be the main cause for the height of the micro-texture cannot be consistent with the amplitude. The effects of AUVAM parameters including material elastic recovery, relief angle, cutting edge arc radius, feed per tooth and spindle speed on micro-texture profile have been researched. The relationship between milling parameters and wettability is also analyzed. Through controlling these parameters, the whole micro-texture surface consistent with the set amplitude can be directly obtained by AUVAM, a controllable design of surface hydrophobicity is also achieved.
