规则的表面纹理可以通过非常规的研磨操作产生。该方法的简单版本在于用具有比磨削深度更深的螺旋槽的轮进行磨削。轮的工作表面以彼此分离的规则布置的凹槽的形式复制在工件上。规则的表面纹理由两部分组成：确定性，由名义砂轮表面产生，和随机性，由随机形状和排列的磨料颗粒产生。模拟和实验揭示了有限的贡献的随机成分的表面结构的工作材料。磨料颗粒的随机排列仅在局部（微观）水平上是重要的，并且影响凹槽底部的粗糙度，而凹槽的尺寸和排列仅在最小程度上受到影响。
Regular surface texture may be generated by an unconventional grinding operation. The simple version of the method consists in grinding with the wheel having helical grooves which are deeper than the grinding depth. The wheel active surface is reproduced on the work-material in the form of regularly arranged grooves separated from each other. Regular surface texture consists of two components: deterministic, resulting from the nominal wheel surface, and stochastic, resulting from the random shape and arrangement of abrasive grains. Simulations and experiments revealed the limited contribution of the stochastic component of the surface structure of the work-material. Random arrangement of abrasive grains is important only at local (micro) level and affects the roughness of groove bottoms, while the dimensions and arrangement of the grooves are affected only to a minimal degree.
