Abstract: It is known that the efficiency of an abrasive tool is primarily determined by the physico-mechanical properties of the abrasive grain, as well as the qualitative properties of the bundle. However, the assessment of these indicators by existing methods does not allow us to accurately predict the properties of the finished instrument. This circumstance leads to the fact that the manufacturing process of an abrasive tool is accompanied by a sufficiently high percentage of defects or the development of new types of it is difficult. Therefore, it is very important to evaluate the basic properties of abrasive materials. Thus, one of the most important properties of an abrasive grain is its cutting ability. This property was evaluated using special techniques using the RSZ-2 device, developed in the 80s of the last century. However, these methods are either quite time-consuming, and the device itself is already obsolete, which reduces the efficiency of the analysis and processing of the results. It is worth noting that the devices do not have automated collection and processing of the experimental information received. Thus, it is necessary to modernize existing devices so that they meet modern realities in the field of instrumentation and presentation of the results of tests performed on them. The article considers an approach to the modernization of the above-mentioned device. A block diagram of the automated control system of the device is presented and the operation of its upgraded version is described. The upgraded version of the device will allow conducting experiments to determine the properties of abrasive materials in conditions that were previously unattainable, as well as obtaining measurement information to assess energy performance, thereby determining the efficiency of various abrasive materials.
