The aim of the work is to increase the productivity of workpiece processing on CNC machines. To achieve this goal, a system of block-modular cutting tools and a solution to the problem of equalizing the durability of various types of cutting tools during cutting and increasing their reliability based on technological regulations for defect detection and adjustment outside the machine are proposed. Analytical and experimental research methods are used to determine the dependence of the cutting speed on the durability of the cutting tool, taking into account the indicators of relative durability, the coefficient of material machinability, and the equalization coefficient as the ratio of the value of the processing speed of a given tool to the processing speed of the limiting tool. The system of block-modular cutting tools based on a unified cutting block, which is installed in various types of cutting tools, is considered. The tools have simple in terms of configuration and reliable elements for installing cutting plates in the holder and cutting blocks in the bodies of cutting tools. An algorithm for calculating the coefficient of equalization of durability and developing process regulations is given. The efficiency of the proposed method for equalizing the durability of cutting tools is shown using the example of technological processes for manufacturing parts. The research results can be used in multi-product manufacturingof parts on CNC machines.
