A model for the topography of diamond grinding wheels

A mathematical model is presented to characterize the topography of a freshly dressed resin/metal bonded diamond grinding wheel. The planar grain density, the area due to exposed abrasives and the abrasive protrusion height distribution of a wheel are estimated with regard to the grit size and volumetric concentration of the abrasives. The model indicates that the protrusion height is approximately uniformly distributed and the percentage of area due to exposed abrasives on the wheel surface is independent of the abrasive grit size for a particular concentration.
