Results of modeling of process of vibration diamond grinding of polycrystalline supersolid materials on the basis of diamond and dense modifications of nitride of a pine forest are given. On the present diamond grinding by circles on various sheaves is one of the most widespread methods of shaping of products (including the cutting tools) from polycrystalline supersolid materials. Allowance renting from the processed material is carried out at the same time by its fragile microdestruction in high-speed contact interaction with sharp micro- and submicroedges edges of diamond grains. Thus, the main prerequisite for realization of such process is existence on grains of sharp micro- and submicroedges that is reached by creation of prerequisites of the grains initiating process of continuous self-sharpening at diamond grinding. Now for optimization of costs of scientific research the optimum combination of machine and model experiments has considerable prospect. By consideration of possible options of CAD systems the conclusion was drawn that for modeling of vibration grinding by the most suitable the SolidWorks package containing Simulation plug-in which is based on a finite element method is. It is established that imposing of mechanical oscillations (vibrations) in a processing zone significantly increases the intense deformed state in a zone of contact of diamond grain with the processed material when grinding. It is positive the moments in respect of activation of process of self-sharpening of diamond grains by their micro and macrodestructions. It is established also, that in case of introduction to a zone of processing of mechanical oscillations of tension are evenly distributed along all grain that in turn improves its deduction in a sheaf, and, therefore, promotes fuller use of a resource of diamond grains. Eventually, it leads to increase in efficiency of process of grinding due to increase in productivity of processing and decrease in a specific consumption of diamonds of a circle.
