In this paper the geometry of the grinding wheel effective topography is analyzed. Existing and newly developed abrasive grain geometry models are investigated. Further, different abrasive distribution systems are developed and the grinding wheel surface is generated. The 3D stereomicroscopy at the Scanning Electron Microscope offers the opportunity to measure a three-dimensional profile of the grinding wheel. Hence, the investigations of the real grinding wheel surface can be used as a verification of the developed surface model. Abbott-Firestone-Curves are used as a comparison of the model based topography and the real grinding wheel surface. The variation of the grain geometry and distribution offers the opportunity to adapt the simulation to the grinding wheel specification.
