The purpose of this study is to study the patterns of energy transfer between the treated surface and the dispersed system and its effect on the polishing performance of optical surfaces. Based on the cluster model of polishing, it is shown that the removal of the processed material occurs as a result of intermolecular interaction between the processed surface and the polishing dispersed system. The intensity of material removal from the treated surface depends on the operating and kinematic parameters of the polishing process, the rheological properties of the dispersed system, as well as the electrical and optical characteristics of the material being processed and the dispersed system. When the particles of the polishing powder interact with the processed material during polishing, clusters are excited on their surfaces due to the vibration energy of the excited clusters of the counterbody, that is, energy is transferred from the dispersed system to the treated surface and in the opposite direction from the treated surface to a particle of the dispersed phase of the polishing dispersed system. As a result of the research, it was found that during the exchange interaction between the treated surface and the dispersed system, the resonant energy transfer occurs according to the Ferster mechanism and significantly depends on the ratio of the vibration frequencies of molecular fragments of clusters on their surfaces. It is shown that with a decrease in these ratios, the size of the particles of sludge and wear particles increases, the energy required for their formation decreases, as a result of which the productivity of polishing and the intensity of wear of the polishing powder increase. It is advisable to use the results of the study in the development of polishing processes for non-metallic materials, as well as in further studies of the regularities of chemical-mechanical polishing of ultra-smooth surfaces.
