This study has been done for the purpose of understanding the mechanisms by which the grinding wheel topographies are formed. The irregularity of distribution of grain tips over the wheel surface and the complexity of their morphology can be characterized by the fractal dimensions. Therefore, it was investigated how the fractal dimensions correlated with the dressing parameters and the composition and properties of wheels themselves. Based on the experimental data, the models adequate to describe the mechanisms were built by the technique, which is called “group method of data handling”. On the basis of the obtained models, the following conclusions could be drawn. (1) The dressing at bigger depth of cut on the harder-grade and more open wheel results in the increased morphological complexity of grain tips. (2) The finer dressing on the denser wheel results in the decreased irregularity of grain tips distribution.
