Technological limitations, such as temperature deformations and the need for subsequent high-precision machining of critical surfaces, arise when using additive technologies for their manufacturing.</p> <p><bold>AIM:</bold> Development and justification of an integrated design and technological approach to the production of compressor and turbine wheels of a micro turbojet engine combining additive technologies and mechanical post-machining.</p> <p><bold>METHODS:</bold> The study examines structural elements to compensate for negative temperature effects, special supporting structures, elements for subsequent precise datum setting at a computer numerically controlled five-axis machine, allowances for post-machining. In addition, the study shows the technology of post- machining, including the preparation of machining datum surfaces on a universal machine, CAD preparation of the machining project, selection of tools, tooling and cutting modes, machining the final shape of the blades at a five-axis milling machine.</p> <p><bold>RESULTS<italic>:</italic></bold> An integrated approach including design and technological solutions has been developed. A comparison of the labor intensity of the proposed and traditional production methods is carried out, showing a reduction in manufacturing time. Quantitative results of roughness measurement on critical surfaces after finishing are presented.</p> <p><bold>CONCLUSION:</bold> The practical value of the study lies in proving the applicability and effectiveness of the developed approach for the mass production of complex aircraft engine parts. The completed study and proposed solutions make it possible to overcome the key limitations of additive technologies and to ensure the manufacturing of products with high quality and precision properties.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Производство сложнопрофильных деталей авиационных двигателей, таких как колёса компрессора и турбины, традиционными методами механической обработки является трудоёмким и длительным процессом.
