AB - This article proposes a simulation model for the fractal characteristics of  grinding wheel surfaces generated based on specified roughness parameters.  The new model is based on the relationship between roughness parameters and  fractal dimension, and uses a random Weierstrass-Mandelbrot function and  Johnson transformation system to obtain a surface point cloud matrix with  non-Gaussian random distribution. Then, the spacing of this matrix was  adjusted using random number algorithm and fractal interpolation algorithm  to obtain a matrix of abrasive distribution with randomness and  self-affinity. The ablation study proved that the model is superior to the  fractal function model in calculating roughness parameters. This achievement  is of great significance for optimizing the design and manufacture of  grinding wheels and improving the quality of grinding operations.
