Ulianov Chuvash State University, 15 Prospekt Moskovsky, Cheboksary, Chuvash Republic, 428015, Russian Federation Abstract In the work the questions concerning prospects of application of nonmetallic composite materials in designs for various industries are considered. The specifics and difficulties of blade processing of composites, related to their special properties, which are qualitatively different from cutting traditional construction materials, are noted. These problems significantly reduce the efficiency of blade processing and the quality of the surface to be treated. The basic schemes describing the process of interaction of the grinding wheel with the cutting element during grinding are given. The ways of solving the problem are proposed by predicting the destruction of the cutting element of a hard alloy tool for processing nonmetallic composites. A description is given of a technique based on the theory of brittle fracture of a material that makes it possible to improve the quality of the cutting edge of a carbide tool by selecting rational tool materials and the conditions for grinding them. Conclusions and perspectives of further research are formulated Keywords grinding, prediction, damage, hard alloy, cutting tools, quality, non-metallic composites
