Abstract
Formation of the ground surface is the result of the interaction of the cutting elements of the diamond tool with the material being processed, so the nature of the working surface geometry of the grinding wheel (WSW) has principal value on processed surface quality. One of the main parameters that characterize the geometry of the WSW is the law of the grain distribution vertex in height. However, statistical models do not reflect the real picture of the tool interaction with the material being processed in the modelling process of grinding tool on the elastic ligament used for final operations. In the process of contact with the material being processed each diamond grain is moved with an adjacent block ligament, changing the position of the cutting vertex relative to both the midrange cords level and the other grains vertexes. As a result the nature of the grain vertexes distribution changes and the conditions of interaction with the material being processed change too. Studies have shown that the density distribution in height of diamond grains elastic grinding tool vertexes in a static state can be described by different distribution laws. For practical use in the calculation of the processed surface roughness and processing capacity is sufficient to approximate the distribution in height only the most protruding grains. In the area of contact with the processed material the distribution density of the grains elastic tool in height significantly differs from the static characteristics and is defined by the elasticity degree of the grinding tool ligament and machinability index of the workpiece material. The obtained results can serve as initial data for the calculation of the processed surface roughness.
