Elliptical vibration texturing is a newly arising method for the fast and cost-effective generation of near-subwavelength micro-structures on metal surfaces. This study proposes a fabrication method for structurally colored basso-relievo by combining the surface sculpturing and elliptical vibration texturing in one-step machining. Synergistic modulations of both nominal cutting speed and depth-of-cut (DOC) in elliptical vibration texturing are applied to provide concave-convex topography and structural coloration. A new rendering strategy for the face turning configuration with an equidistant spiral tool path has been presented to improve the image rendering efficiency over the raster scan tool path. In addition, different from the conventional elliptical vibration texturing, the nominal DOC dynamically changes pixel by pixel in the proposed new process. In order to identify the effects of DOC and elliptical vibration trajectories on the surface quality and fidelity of generated gratings, grooving experiments have been conducted on brass samples to further the understanding of nonlinear tool-workpiece interactions. Finally, both raster scan and face turning tests have been performed on an ultraprecision platform with optimized process parameters. Structurally colored basso-relievos with high quality have been successfully demonstrated using the proposed fabrication method.

椭圆振动纹理化是一种新出现的方法，用于在金属表面上快速且经济高效地生成近亚波长的微结构。这项研究提出了一种结构着色的贝索浮雕的制造方法，该方法通过在一步加工中将表面雕刻和椭圆振动纹理化相结合。椭圆振动纹理化中的标称切削速度和切削深度（DOC）的协同调制可提供凹凸形貌和结构着色。已经提出了具有等距螺旋刀具路径的人脸转向配置的新渲染策略，以提高光栅扫描刀具路径上的图像渲染效率。另外，不同于常规的椭圆振动变形，标称DOC在建议的新流程中逐像素动态更改。为了确定DOC和椭圆振动轨迹对所生成光栅的表面质量和保真度的影响，已对黄铜样品进行了开槽实验，以进一步理解非线性工具-工件相互作用。最终，在具有优化工艺参数的超精密平台上执行了光栅扫描和面部翻转测试。使用所提出的制造方法已经成功地证明了具有结构色彩的高品质低音提琴。
