Quantitative Measurement of Grit Distribution of Diamond Abrasive Tools
摘要
Abstract
This paper putted forward two parameters to evaluate the grit distribution quantitative-ly,which were as static grit density Cs and the distribution uniformity CV .The grit centroids were ob-tained from the binary picture processed from the SEM picture of the diamond tools.The static grits density Cs was obtained by counting the number of centroids.On the other hand,the area of every cen-troid was obtained through the Voronoi diagram approach.The distribution uniformity CV was defined as the coefficient of variation of the Gamma distribution of centroid area.Using the two parameters to evaluate quantitatively the grit distribution for the same wheel surface and different grit distribution surfaces,the results show that the grit distribution morphology can be evaluated better with those pa-rameters.关键词
