Manufacturers are always looking for new ways to improve these materials' machinability using cutting-edge cutting tool technologies and suitable cooling methods. In this context, rotary tools have shown significant potential for better performance in machining challenging materials. <bold>The purpose of the work. </bold>It is essential to comprehend geometric dimensioning and tolerance (GD&amp;T) parameters when machining aerospace alloys to ensure precision and interchangeability in parts manufacturing. However, limited studies have investigated these parameters while considering the effect of nanofluids during turning with rotary tools. <bold>Methods of investigation. </bold>This study explores the turning of Inconel 718 with a hybrid nanofluid under minimum quantity lubrication (NFMQL) conditions using a self-propelled rotary tool (SPRT). Nanofluids were prepared by mixing Al?O? and multi-walled carbon nanotubes in palm oil. The analysis of worn tools was performed through optical and SEM images. Further, the radial GD&amp;T parameters, such as circularity, cylindricity, radial runout, surface roughness, tool life, and workpiece hardness, are discussed as they vary with the cutting conditions. Additionally, the technique for order of preference by similarity to the ideal solution (TOPSIS) in association with a genetic algorithm (GA) was used to generate Pareto solutions and select the optimal compromise solution. The work with the optimized parameters is finally summarized. <bold>Results and Discussion. </bold>A hybrid nanofluid under NFMQL conditions was used to assess the processability of Inconel 718 during turning with an SPRT. The circularity, cylindricity, radial runout, and machined surface characteristics were investigated. The worn tools have been examined through optical and scanning electron microscopy images. Surface roughness and tool life are significantly affected by feed and cutting speed, while cylindricity is strongly impacted by the depth of cut. Pareto fronts and the best compromise solutions were obtained using a genetic algorithm integrated with TOPSIS. This study found that turning Inconel 718 at a feed rate and depth of cut of 0.1 mm/rev and 0.2 mm, respectively, and a cutting speed between 30–60 m/min could achieve circularity and cylindricity deviations of up to 5.68 µm and radial runout of up to 0.43 mm, as well as surface roughness, tool life, and workpiece hardness in the ranges of 1.07–1.54 µm, 3.46–8.44 min, and 36–38 HRC, respectively. This research provides valuable insights for designing an SPRT and promoting its wide adoption and application in the machining domain for machining superalloys. This study suggests exploring nanoparticle agglomeration in nanofluids and the use of additives to improve machining efficiency. Additionally, this research identifies opportunities to enhance machining performance under NFMQL conditions by utilizing micro-textured SPRTs with nanofluids, addressing concerns related to machined surface integrity.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Жаропрочные сплавы, в частности никелевые, имеют критическое значение в авиа- и ракетостроении, а также в аэрокосмической отрасли в целом благодаря сочетанию высокой износостойкости и прочности. Однако существенный нагрев в зоне резания при их механической обработке создает значительные технологические сложности. Производители постоянно ведут поиск новых подходов к повышению обрабатываемости таких материалов, применяя передовые технологии механической обработки, современный режущий инструмент и эффективные методы охлаждения. В этом контексте вращающиеся инструменты демонстрируют существенный потенциал для повышения производительности при обработке труднообрабатываемых материалов. <bold>Цель работы.</bold> Корректное определение геометрических характеристик и допусков (GD&amp;T) при обработке аэрокосмических сплавов, что является ключевым для обеспечения точности и взаимозаменяемости деталей. Тем не менее влияние наножидкостей на эти параметры в процессе точения вращающимися инструментами изучено недостаточно. <bold>Методы исследования.</bold> В работе исследовался процесс точения сплава Inconel 718 с применением гибридной наножидкости в режиме охлаждения минимальным количеством СОЖ (NFMQL) и использовался ротационный инструмент с собственным приводом (SPRT). Наножидкость была получена диспергированием наночастиц Al?O? и многослойных углеродных нанотрубок в пальмовом масле. Износ инструмента оценивался по данным оптической и сканирующей электронной микроскопии. Проанализирована зависимость радиальных параметров GD&amp;T (отклонение от круглости, цилиндричности, радиальное биение), шероховатости поверхности, стойкости инструмента и твердости заготовки от режимов резания. Для определения оптимальных компромиссных параметров обработки и построения фронта Парето использовалась комбинация метода TOPSIS (техника упорядочения предпочтений по сходству с идеальным решением) и генетического алгоритма (GA). В завершение представлены обобщенные результаты оптимизации. <bold>Результаты и обсуждение.</bold> Для оценки обрабатываемости сплава Inconel 718 при точении инструментом SPRT в условиях NFMQL применялась гибридная наножидкость. Исследованы отклонения от круглости и цилиндричности, радиальное биение, а также характеристики обработанной поверхности. Анализ износа инструмента выполнялся методами оптической и сканирующей электронной микроскопии. Установлено, что шероховатость поверхности и стойкость инструмента в наибольшей степени зависят от подачи и скорости резания, в то время как отклонение от цилиндричности наиболее чувствительно к глубине резания. С помощью комбинации генетического алгоритма и метода TOPSIS были получены фронт Парето и набор наилучших компромиссных решений. Показано, что точение сплава Inconel 718 при подаче 0,1 мм/об, глубине резания 0,2 мм и скорости резания 30…60 м/мин позволяет достичь отклонений от круглости и цилиндричности до 5,68 мкм, радиального биения – до 0,43 мм, а также следующих диапазонов значений: шероховатость поверхности 1,07…1,54 мкм, стойкость инструмента 3,46…8,44 мин, твердость заготовки 36…38 HRC. Результаты работы представляют ценность для проектирования самовращающихся инструментов и способствуют их широкому внедрению в практику обработки жаропрочных сплавов. Перспективными направлениями дальнейших исследований являются изучение агломерации наночастиц в наножидкостях и применение модифицирующих присадок для повышения эффективности обработки. Кроме того, потенциал повышения производительности в условиях NFMQL может быть реализован за счет использования микротекстурированных самоустанавливающихся вращающихся инструментов в комбинации с наножидкостями, что также позволит улучшить показатели целостности поверхностного слоя.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Turning</kwd><kwd>Inconel 718</kwd><kwd>MQL</kwd><kwd>Rotary tool</kwd><kwd>Nanofluid</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Точение</kwd><kwd>Inconel 718</kwd><kwd>MQL</kwd><kwd>Вращающийся инструмент</kwd><kwd>Наножидкость</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Rajurkar A., Chinchanikar S.
