New Patterns of Polishing Surfaces of Parts Made of Nonmetallic Materials

Abstract

As found from the results of studying the mechanism of polishing precision surfaces of nonmetallic parts by dispersion systems based on micro- and nanoparticles of polishing powders, the formation of sludge particles, a polishing powder, and grinding particles is a consequence of the Förster resonant energy transfer (FRET). This occurs in the resonator formed by two parallel surfaces of the work piece and the polishing paste. It is shown that the productivity of polishing of nonmetallic materials increases nonlinearly with an increase in the quality factor of the resonator, while the roughness of the treated surfaces deteriorates. The relationship between the quality factor and the optical length of the resonator is established, and it is shown that the maximum values of the removal rate of the treated material, the intensity of wear of the polishing powder, and the wear of the grinding surface are achieved at a certain optical length of the resonator. It is equal to the number of half waves, which is characteristic of nanoparticles of the sludge, polishing powder, and grinding material. It is shown that the productivity of polishing the parts made of nonmetallic materials and the roughness of their polished surfaces are extremely dependent on the dielectric constant diffrenece between the processed material, the polishing powder, and the dispersion system.
