Experimental Research on the Relation Between Processing Parameters and Fractal Dimensions of the Machined Surface

In the finishing machining, processing parameters directly affects the quality of machined surface. While the micro topography of the surface maps with the fractal dimensions. The paper researched the relation between processing parameters and fractal dimensions through the experiments in order to obtain the relationship. Through the design of orthogonal rotation experiment, determine the experimental parameters. Then measure the experimental sample for the surface and calculate the fractal dimensions using the box counting method. In the end, obtain the functional relation of processing parameters and fractal dimensions by regression method. The results show that the specific processing parameters of the surface can predict the fractal dimension by this formula. And this provides reference for selection of processing parameters.
