The three-dimensional micrograph was managed to a binarization image

and then the agglomeration area of binarization image was treated as the multiple particles

and the single particle was regarded as a mass point.All these disposing process of EPS/CBN composite foam pattern will use to obtain a distribution of the points that can accurately characterize the CBN abrasive distribution of composite foam sample.Furthermore

the distribution of the points was constructed as a Tyson polygon.Applying Tyson polygon area statistical analysis

the uniformity of abrasive distribution in the composite foam sample was evaluated quantitatively.Finally

the method was used to evaluate the surface abrasive distribution uniformity of different EPS/CBN composite foam pattern that generated at different process.The results reveal that the obtained parameters can be used effectively to evaluate uniformity of abrasive distribution configuration with abrasive agglomeration.
