Abstract

Purpose. To solve a scientific and technical problem related to the technological support of mechanical processing of a part manufactured using additive technologies by optimizing and controlling its machinability with cutting tools made of hard alloys on modern numerically controlled machine tools. Methods. The methodology is based on the use of numerical and grapho-analytical research methods to establish a systematic relationship between the parameters of mechanical processing of a part and the properties of the material being processed, the geometry of the tool, and their corresponding integration into the control program of the machine tool and 3D printer. Findings. Numerical results of research were obtained for a scientifically based approach to solving the scientific and technical problem of productive combined processing of stainless steel parts on a numerically controlled machine 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, measurement results, and quality control. 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 made it possible for the first time to obtain comprehensive dependencies in a form convenient for calculation and analysis, which give a clear idea of the influence of each parameter of the turning process on the machine tool. Practical implementation. It consists in selecting and justifying the optimal geometric parameters of cutting tools, establishing the nature of the influence of stainless steel blade processing conditions on the main indicators of the process – 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.
