Ulianov Chuvash State University, 15 Moskovsky Prospekt, Cheboksary, 428015, Russian Federation 2Novosibirsk State Technical University, 20 Prospekt K. Marksa, Novosibirsk, 630073, Russian Federation Abstract The cutting tool should be properly prepared and sharpened to ensure the required quality of the product. This is important, since the accuracy, speed and efficiency of the material processing depend on the condition of the tool. High-strength tool materials, such as carbide alloys, high-speed steel, ceramic materials and others, have excellent mechanical properties, which allow it to withstand high loads and temperatures during the processing of various materials. However, in order to effectively use its potential, it is necessary to properly prepare and sharpen the cutting elements. The process of sharpening a metal-cutting tool includes several stages, such as grinding, turning, and possibly the use of special coatings and chemical processing. All these operations are performed with high precision and in accordance with the requirements of the technological process of materials processing. It is necessary to control quality parameters to assess the quality of sharpening of plates made of high-strength tool materials after various types of traditional and integrated technologies at the stage of tool production planning. Numerical values of the values of serration and radius of rounding make it possible to conduct a comparative analysis of various shaping methods. Keywords high-strength tool materials, serration, wear, cutting blade quality, sharpening methods, rounding radius.
