ABSTRACT

Purpose. To solve a scientific and technical problem related to high-speed milling of a part from a selected material by optimizing and controlling its machinability with a hard alloy tool 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 cutting parameters and the properties of the material being processed, tool geometry, and corresponding integration into specialized engineering programs.

Findings. Numerical research results were obtained for a scientifically based approach to solving the scientific and technical problem of productive milling of a part from a selected material on a machine tool, containing a set of adjusted algorithms for predicting machinability while ensuring the reliability of the cutting tool. 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.

The originality. Establishing a complete and systematic relationship between processing parameters and the properties of the material being processed, tool geometry, and design and technological factors 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, providing a clear picture of the influence of each parameter of the milling process.

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: high-speed milling, machine tools, CNC, rotation frequency, workpiece, cutting edge, optimization of cutting modes.
