Evaluation of surface topography of metal-bonded diamond wheel utilizing three-dimensional profilometry

摘要: A three-dimensional profilometry has been developed for the purpose of evaluating grinding wheel surface topography. By applying this method to the measurement of topography of a metal-bonded diamond wheel dressed by an abrasive stick method, the effect of dressing conditions on the generation mechanism of diamond cutting points has been investigated. The results obtained are as follows.(1) The tips of the diamond grains located in the wheel outermost surface layer are flattened.(2) The distribution pattern of cutting points in the radial …
