Abstract: In this study, the direct method based on the polishing for obtaining micro-grinding wheel topography was proposed and compared with the optical method. The proposed method provides fine details for the size of grits and the diameters of micro-grinding. The size distribution and profile of the grits were also obtained using the direct method. It was also found that a new method for characterisation of microscale grinding wheels, referred to as the direct method, is more effective to obtain the size distribution of grits and the static and dynamic cutting density of micro-grinding wheels in comparison to the optical method.
