表面微观结构可以提供各种功能，润湿性是一种典型的表面特性，可以由表面纹理控制。本研究试图通过超声辅助面铣削（UAFM）制造分层微结构，通过特别关注润湿性来改变表面功能。制造过程包括使用超声波产生主轴和自行设计的金刚石工具。根据运动方程计算了金刚石刀具刀尖的运动轨迹，并对刀尖的微观和宏观结构进行了分析。这些结构通过白光干涉仪的观测得到了证实。对加工区域的六个区域的润湿性进行了测量，结果表明，UAFM表面的中心区域变为疏水区域，而边缘区域变为亲水区域。
Surface microstructures can provide various functionalities, and wettability is a typical surface property that can be controlled by the surface textures. This study attempted to fabricate hierarchical microstructures through ultrasonic-assisted face milling (UAFM) to change the surface functionality by specifically focusing on the wettability. The fabrication involved the use of an ultrasonic generating spindle and a self-designed diamond tool. The locus of the tip of the diamond tool was computed based on the equation of motion, and the micro- and macrostructures are illustrated in this paper. The structures were confirmed through observations using a white-light interferometer. The wettability on six zones of the processed area was measured, and the results indicated that the central zone of the UAFM surface became hydrophobic, whereas the edge zone became hydrophilic.
