Calculation model of the glass-binder volume fraction in the abrasive ceramic tool

A computational model is proposed for the volume fraction of a glass bond in an abrasive ceramic tool, according to which glass interlayers between abrasive grains are composed of spherical particles, and the shape of the grains is approximated by various bodies of revolution: spheres, cylinders, and two paraboloids docked around the circumference. The use of the model makes it possible to estimate the minimum amount of glass bond, at which no contact bridges are formed between the grains, as well as the thickness of the glass interlayers between the grains.
