Ulyanov, 15 Prospect Moskovsky, Cheboksary, 428015, Russian Federation Abstract The article outlines the problems of the prospects of using polymer composite materials in various designs and processing methods. A brief comparative analysis of the processing methods of polymer composites is given, revealed. that the mechanical (blade) method is more versatile and widespread in application for cutting non-metallic composites. The study of the formation of serration on the cutting blade of a tool designed for processing polymer composite materials. It has been established that it is either not possible or quite laborious to ensure the required quality for a tool equipped with carbide cutting elements using the traditional methods described in various references, where the result is not constant and not stable, because the resulting damage to the cutting blade in this case does not lie in the permissible range of 0.004 ... 0.007 mm. Therefore, the research subject needs further study in the direction of using new progressive, combined methods of processing high-strength tool materials. The nature of the influence of cutting conditions during grinding of carbide cutting elements of a tool intended for processing polymer composite materials on the formation of serration and stress-strain state of the plate after processing is revealed. The conclusions and prospects of further research are formulated. Keywords Grinding, serration, carbide, cutting tools, quality, polymer composites
