The paper presents issues related to shaping the topography of the grinding wheel as a result of the impact of a stationary multipoint diamond dresser. The result of the dressing process with diamond multipoint dressers is influenced by the dressing feed, the effective width of the individual diamonds and the distance between the diamonds measured along the dressing feed direction. The paper presents simulation results the influence of these parameters on the multiplicity of contact between generatrix of the flat grinding wheel type 1 and the dressing diamonds. The results of the simulation showed that, depending on these parameters, areas with no contact with diamonds and areas with different multiplicity of contact may form on the surface of the grinding wheel. This means that the active surface roughness of the grinding wheel may not be uniform. Two indexes were proposed to enable supervision of the dressing process using stationary multi-point dressers. The first index (k1) characterizes the average multiplicity of contact between the diamonds and the grinding wheel along its generatrix, and the second (k2) the possibility of forming a spiral ridge on the grinding wheel surface due to the lack of contact between this part of the grinding wheel and the diamonds. The work analyzes the changes in the indexes values as a function of the dressing feed rate and the active width of diamonds for two basic types of diamond distribution on the working surface of the dresser, i.e. uniform and irregular spacing. The study presented the results of evaluating the topography of the flat aluminum oxide vitrified grinding wheel type 1 subjected to dressing with various values of indices k1 and k2. The assessment was carried out on the basis two-sample Kolmogorov-Smirnov test and statistical analysis of parameters for evaluating the microgeometry of the grinding wheel circumferential profile, i.e. the depth of active cutting edges and the undeformed chips thickness. The analysis confirmed the lack of homogeneity of the surface topography of the grinding wheel formed with a stationary multipoint dresser and the purposefulness of using the k1 and k2 indexes.
