In this paper we first contrast classical and CNC polishing techniques in regard to the repetitiveness of the machine motions. We then present a pseudo-random tool path for use with CNC sub-aperture polishing techniques and report polishing results from equivalent random and raster tool-paths. The random tool-path used - the unicursal random tool-path - employs a random seed to generate a pattern which never crosses itself. Because of this property, this tool-path is directly compatible with dwell time maps for corrective polishing. The tool-path can be used to polish any continuous area of any boundary shape, including surfaces with interior perforations.
在本文中，我们首先就机器运动的重复性对比了传统抛光技术和计算机数控（CNC）抛光技术。然后，我们提出一种用于CNC子孔径抛光技术的伪随机刀具路径，并报告等效随机和光栅刀具路径的抛光结果。所使用的随机刀具路径——单一路径随机刀具路径——采用随机种子来生成从不自我交叉的图案。由于这一特性，该刀具路径可直接与用于校正抛光的驻留时间图兼容。该刀具路径可用于抛光任何边界形状的任何连续区域，包括带有内部穿孔的表面。
