When a scanning laser microscope is used as a tool for measuring the three-dimensional shape of abrasive diamond grains, the result is often distorted due to the presence of noise. After the noise has been removed, a three-dimensional modeling is considered in order to enhance the shape obtained. In the proposed modeling method, the grain body is extracted from the bond surface and horizontally divided into layers. The contour of each layer is modeled by a technique called the cam and follower method, and then the modeled layers are overlapped in order to generate the modeled grain shape. The obtained results are employed for measurements of various shape features of diamond abrasive grains.
