ABSTRACT

Purpose. To solve scientific and technical problems related to the technological support of mechanical processing of alloy steel parts by optimizing and controlling their machinability with hard alloy tools on modern CNC machines.

Methods. The methodology is based on the use of numerical and grapho-analytical research methods to establish a systematic relationship between the parameters of blade processing and the properties of the processed material, the geometry of the tool, and its stability, and their corresponding integration into the machine control program.

Findings. Numerical research results were obtained for a scientifically based approach to solving the scientific and technical problem of efficient combined machining of alloy steel parts on a machine tools, containing a set of adjusted algorithms for predicting machinability while ensuring the reliability of cutting tools. The results obtained were compared with known works related to the study of mechanical processing of various materials, assessment of the reliability of cutting tools, accuracy and roughness of the machined surface, and the results of measurements of cutting force parameters.

The originality. The study focused on establishing a complete and systematic relationship between processing parameters and the properties of the material being processed, tool geometry, and design and technological features of the part to calculate the optimized technology for automated production. Mathematical and statistical processing of experimental data, which made it possible for the first time to obtain comprehensive dependencies in a form convenient for calculation and analysis, was performed, which give a clear idea of the influence of each parameter of the turning process on its energy and time indicators.

Practical implementation. It consists in selecting and justifying the optimal geometric parameters of cutting tools, establishing the nature of the influence of alloy steel blade processing conditions on the main process indicators – machining time and operating parameters, depending on the hardness of the part material and tool material. Practical recommendations are provided for the optimal use of the obtained data in CAM systems.

Keywords: mechanical processing, machine tool, alloy, technology, stability, cutting tool, cutting modes, CAD, CAM.
