Tooling materials science| Zusammenfassung: | The purpose of this work is to study the regularities of removal of the processed material and the formation of a nanoprofile of polished optical surfaces of copper and aluminum parts during polishing using disperse systems of micro- and nanopowders of copper metaborate and cerium dioxide. As a result of the study of the regularities of polishing optical surfaces of parts made of copper and aluminum, it was found that the removal rate of the processed material increases with an increase in the quality factor of the microresonator formed by the surfaces of the processed material and particles of polishing powder, an increase in the lifetime of quantum dots on the processed surface in the excited state, the volumetric wear coefficient, and the most probable size of sludge nanoparticles, which indicates the same regularities of polishing optical parts made of copper and aluminum and non-metallic materials. It is established that the roughness parameters Ra, Rq and Rmax of polished surfaces of optical parts made of copper and aluminum increase linearly with increasing Q factor of the microresonator and increasing the most probable size of sludge nanoparticles in accordance with the general laws of polishing. It is shown that the theoretically calculated values of the removal rate of the processed material during polishing of copper and aluminum using disperse systems of micro- and nanopowders of copper metaborate and cerium dioxide are in good agreement with the data of experimental determination of polishing productivity with a deviation of 2–5%. The feasibility of using the polishing disperse system of micro- and nanopowders of copper metaborate for polishing optical surfaces of parts made of copper and aluminum, which provides the required roughness of polished surfaces at a high removal rate of the processed material, is substantiated. The results of the study should be used in the development of technological processes for polishing optical surfaces of copper and aluminum parts. |
