Pressure gradient and geometrical variation of the abrasive blocks during the polishing process of ceramic tiles with line contact

A series of experimental investigation has been carried out to develop and describe the distribution of pressure gradient underneath and across the topological surface of laboratory grinding tools. The surface pressure plays a key role during polishing process of ceramic tiles in gloss gaining and...
