提出了一种新的旋转超声毛化（RUT）技术，用于在平坦表面上制备混合周期性微/纳米织构。与传统的旋转超声加工不同，研制了一种定制的单点金刚石刀具，并将其用于化学镀镍磷（Ni-P）层表面的超声快速腐蚀（RUT）。使用一维的振动模态。超声振动、旋转运动和进给运动的共同作用导致了切削刃运动的高频周期性变化，这是超声旋转超声加工的基本原理。因此，为了准确地预测和控制变形过程，首先对切削轨迹进行数学计算。在机械加工表面上成功地制备了微米级线性沟槽和微米级或纳米级正弦沟槽的混合周期性微/纳米织构，其结果与数学计算的结果一致。通过改变加工条件，生成不同类型的表面纹理。通过分析RUT的表面纹理特征、切削轨迹和刀尖几何形状（包括各种刀具面、切削刃和切削角），说明并讨论了RUT的表面生成机理。总结了RUT技术的要求。(C)2014爱思唯尔有限公司版权所有。
A novel rotary ultrasonic texturing (RUT) technique is proposed to fabricate hybrid periodic micro/nano-textures on flat surfaces. Different from conventional rotary ultrasonic machining, a tailored one-point diamond tool was manufactured and employed for RUT on surfaces of electroless nickel-phosphorus (Ni-P) plating. A one-dimensional longitudinal-vibration mode is used. The combined effect of ultrasonic vibration, rotation and feed motion leads to high-frequency periodic change of cutting edge's motion, which is the basic principle for the RUT process. Therefore, to accurately predict and control the texturing process, the cutting locus is firstly mathematically calculated. Hybrid periodic micro/nanotextures comprising linear grooves at the micrometer scale and sinusoidal grooves at the micrometer or nanometer scale were successfully fabricated on machined surfaces, which are in compliance with the results of the mathematical calculations. Different types of surface textures were generated by changing machining conditions. The surface generation mechanism of RUT is illustrated and discussed by analyzing the surface textural features, the cutting locus and the tool tip's geometry, including various tool faces, cutting edges, and the cutting corner. The requirements for RUT technique are concluded. (C) 2014 Elsevier Ltd. All rights reserved.
