提出了微凹坑加工来控制固体表面上微尺度结构的表面功能。使用倾斜球头立铣刀铣削微凹痕。当倾斜的双刃立铣刀以小于刀具半径的切削深度去除材料时，两刃与工件接触期间的空切时间出现在刀具的旋转中。当刀具以高进给速度进给使得一个边缘和另一个边缘的去除区域不彼此重叠时，就会加工出凹形凹坑。提出了一个机械模型来控制要加工的凹坑的形状和尺寸。加工微凹坑以验证铣削中的机械模型。使用凹痕表面在模制时也形成微小凹凸。作为功能表面的应用，在具有凹痕和凹凸的表面上测量润湿性和摩擦系数。表面函数随着凹坑和粗糙体的排列而变化。
A micro dimple machining is presented to control the surface functions with the micro-scale structures on the solid surfaces. The micro dimples are machined in milling with the inclined ball end mill. When an inclined two flutes end mill removes the material in a depth of cut less than the tool radius, the air cutting time during neither edges contact with the workpiece appears in a rotation of cutter. When the tool is fed at a high feed rate so that the removal areas of an edge and another edge do not overlap each other, the concave dimples are machined. A mechanistic model is presented to control the shape and the size of the dimples to be machined. The micro dimples were machined to verify the mechanistic model in milling. The micro asperities were also formed in molding using the dimpled surface. As applications of the functional surfaces, wettability and friction coefficient were measured on the surfaces with the dimples and the asperities. The surface functions change with the alignments of the dimples and the asperities.
