构成这些结构的微槽、微窝或层次化表面在许多工业领域中具有很高的功能性能要求。在本研究中，发展了一种新的二维旋转超声毛化(RUT)技术，以高效地制造这些精密表面结构。为实现二维车辙加工，设计并制造了一种能在垂直于主轴轴线的水平面上产生环形振动的旋转超声主轴。介绍了主轴结构和变形原理。对表面形成机理进行了数学分析和实验验证。为进行表面毛化实验，设计并制造了一种具有几何形状刃口的金刚石刀具。成功地制备了由几个微米到几十个微米的周期性沟槽组成的不同类型的几乎无毛刺的织构表面，其织构特征与理论预测吻合得很好。讨论了新的2D车辙技术的材料去除机理、刀具设计原则和可加工结构。
Microgrooves, microdimples, or hierarchical surfaces comprising these structures are highly required in many industrial fields for their functional performances. In the present research, a novel two-dimensional (2D) rotary ultrasonic texturing (RUT) technique is developed for efficiently fabricating these precision surface structures. A rotary ultrasonic spindle that can generate circular vibration on the horizontal plane perpendicular to the spindle axis was designed and manufactured for carrying out the 2D RUT processes. The spindle structure and the texturing principle are introduced. Surface generation mechanisms are mathematically analyzed and experimentally verified. A diamond tool with geometrically defined cutting edge was designed and manufactured for carrying out the surface texturing experiments. Different types of nearly burr-free textured surfaces composing of periodic grooves from several micrometers to tens of micrometers were successfully fabricated, and their textural features coincide well with the theoretical prediction. Material removal mechanisms, tools design principles, and machinable structures of the new 2D RUT technique are discussed.
