Abstract: As noted by some researchers, despite the successful use of the traditional characteristics of the surfaces evaluation roughness, still required new approaches in evaluating the micro relief properties surfaces. One of these solutions to these problems is to use the basic assumptions of the theory of fractals. If we consider the micro-relief surface as a fractal object, it must, in fact, to assess its "self-similarity" and "symmetry". In general, any surface can be seen in the range of fractal dimension between 2 and 3, where D = 2 - absolutely flat surface or "undeveloped" surface, and D = 3 - absolutely "developed" surface. The aim of this work is to establish the regularities of changing fractal dimension of the surface micro relief in various finishing touch stages, spiral drills. To achieve this goal it is necessary to solve the following problem: on the basis of the scheme process finishing touch, spiral drills, to determine the parameters of the fractal dimensions of surfaces at each stage of processing. Experimental studies were performed on spiral drills with a diameter of 14 mm of steel R6M5 (GOST 10902-77). Technological process of finishing touch, twist drills with vacuum ion-plasma coatings consist of the following operations: grinding, sanding and polishing
