Ulianov Chuvash State University, 15 Moskovsky Prospekt, Cheboksary, 428015, Russian Federation Abstract The paper presents the main indicators characterizing the process of blade processing. The features of polymer composite materials, the specifics of its processing, taking into account the used cutting tool, its geometry, design and material, are noted. Any production process for the manufacture of products in mechanical engineering is the choice of the most profitable option for the implementation of the technological process with effective indicators such as productivity, reliability, flexibility and mobility of production, environmental friendliness and others. The priority indicator of efficiency is the efficiency of any technological process. The aim of the work is to create a methodology for assessing the efficiency of cutting tools for processing polymer composite materials and technology of blade processing with prefabricated tools. The paper discusses the parameters that affect the assessment of the efficiency of processing such materials, and presents a methodology for assessing the efficiency of cutting tools for processing polymer composite materials and blade processing technology on the example of using a prefabricated tool structure. The ways of implementing the results in practice are presented. Keywords Cost of production, polymer composite materials, tool life, tool performance, tool life period, blade processing with assembled tools, milling, profitability.
