Macroscopic Model of an Abrasive Tool

When designing an abrasive tool, it is necessary to know the most important properties of grain-bond system. The greatest interest study physical and mechanical characteristics tool: hardness, density, bending strength, modulus elasticity, Poisson's ratio, coefficient thermal expansion, properties, etc. There are extensive experimental data on testing tools in which a number empirical formulas have been obtained determine tool (grain size, structure, grain bond grade, etc.). article based core several assumptions hypotheses that limits applicability results obtained, within theory has complete model behavior tool.
