The purpose of this study is to study the influence of the physical properties of the processed material and the dispersion system on the polishing performance of optical parts made of polystyrene. As a result of the study of the polishing mechanism of optical parts made of polystyrene using a dispersed system of micro- and nano-particles of polishing powder, it was established that the formation of sludge nanoparticles of the processed material and wear nanoparticles of the polishing powder is a consequence of FRET between the energy levels of the particles of the polishing powder and the processed material in the four-mode mode, which takes place in an open resonator formed by two parallel surfaces of the processed material and the lapping. It is shown that the removal speed of the processed material and the intensity of polishing powder wear during polishing of polystyrene are determined by the total volumetric wear coefficients for all modes, the total lifetime values of the excited state of clusters of the treated surface and polishing powder particles, and the resulting Q factor of the resonator at all possible frequencies of the discrete spectrum. It was established that the results of the theoretical calculation of the speed of removal of the processed material during the polishing of optical parts made of polystyrene are in good agreement with the data of the experimental determination of the polishing performance with a deviation of up to 3%. It is shown that the roughness of the polished surface depends on the Q factor of the resonator at all allowed frequencies and is characterized by the parameters Ra, Rq and Rmax, which are the superposition of these parameters characteristic of each of the possible modes. It was established that the speed of removal of the processed material and the roughness of the polished surfaces satisfy the requirements for the process of polishing optical surfaces. The research results should be used in the development of processes for polishing polymer optical materials.
