The authors review the methodology for monitoring of operational indicators of abrasive materials. They describe existing methods of evaluating brittle and strength properties of abrasive grain as a construction made of this material, and equipment for assessing the crushability of abrasive grains, their cutting and polishing ability, wear resistance. The possibility of applying the method and apparatus for determining the brittle strength of the abrasive grains of black silicon carbide is illustrated theoretically. It justifies the application of the original device to determine the cutting ability of grinding materials. In the device we implemented the conditions that ensure constant cutting force at the hardware level which allows us to estimate the effect physical, mechanical, and geometrical parameters of abrasive grains have on the intensity of abrasive dispersion of a metal. Specific dispersion energy is introduced as a new indicator for the operation of abrasive grain. The cutting ability of SiC and Al2O3 abrasive grains in the range of different grit and cutting speeds is experimentally studied. The possibility of monitoring operational indicators of abrasive grains of different materials using the RSZ-2 is experimentally confirmed.
