Abrasive surfaces can nowadays be produced incorporating precision cutting features of controlled shape, size, protrusion and location. This study investigates the influence of defined abrasive shapes (square/triangular/conic pyramidal frusta) of designed groups of overlapped abrasives on the successive removal of ductile (Cu) and brittle (Al2O3) materials. Scanning electron microscopy studies combined with detailed micro-topographical evaluations of scratches/adjacent material have revealed the progressive actions of material removal/displacement of copper and the fracture and brittle/plastic transitions of sapphire for the different abrasive shapes, aiding a fundamental understanding of the influence of defined micro-geometries on the grinding process and resulting material surface topography.
