CORRECTIVE POLISHING OF COMPLEX CERAMICS GEOMETRIES

摘要

This paper showed the results of scientific studies with the goal of shortening the development of a stable and reproducible polishing process for corrective machining of complex ceramics samples. The transfer was successful by rendering unnecessary intensivernpreparatory work on polishing strategies and resulted in satisfying overall results with a high and reproducible MRR and surface quality. In terms of the machine parameters, the eccentric frequency shows only a small impact for the profile formation. However, the eccentric radius, the applied normal force and the relative velocity do have significant impact on the formation of the influence function determining the process efficiency. These technological insights were used to accomplish a first corrective polishing by the zonal process. The ongoing research does include the expanding of geometrical complexity up to free formed surfaces of various advanced ceramics. The results will be presented in future publications.
