The relevance of the work is driven by the need to ensure the machining quality of the outer surface while adhering to strict temperature constraints at the metal-polymer interface, imposed by the low thermal resistance of the filler material. <bold>Purpose of the work </bold>is to develop and implement a multi-criteria optimization approach for the finishing turning parameters of the metal-composite system. This approach is based on previously developed regression models for the interface temperature and cutting tool wear, and aims to minimize tool wear while satisfying temperature constraints and surface quality requirements. <bold>Methodology.</bold> The methodology is based on a previously developed 2T3-type regression model for predicting temperature at the metal-metal-polymer interface and a cutting tool wear model formulated as a generalized Fick-Taylor equation for a cemented carbide insert (grade AH6225). Using these models, a mathematical programming problem with a nonlinear temperature constraint is formulated and solved via the sequential quadratic programming (SQP) method within specified ranges of cutting speed, feed rate, and depth of cut. <bold>Results and discussion.</bold> The numerical implementation of the proposed approach yielded the domains of admissible and optimal finishing turning parameters for the metal-composite system, based on criteria of thermal load and tool wear. The depth of cut was identified as the dominant factor influencing the temperature at the metal-metal-polymer interface. It was shown that the temperature constraint defines the boundaries of the admissible parameter domain. Specific combinations of cutting speed, feed rate, and depth of cut were determined that simultaneously satisfy the polymer's temperature limit and ensure an acceptable wear level for the AH6225 carbide inserts.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Рассматривается задача выбора режимов финишного точения металл-композитной системы с тонкостенной металлической оболочкой толщиной 2 мм, полученной методом селективного лазерного сплавления, и внутренним металлополимерным заполнителем. Актуальность работы связана с необходимостью обеспечения качества обработки внешней поверхности при жестком ограничении температуры на межфазной границе «металл – металлополимер» из-за низкой термостойкости заполнителя. <bold>Цель работы:</bold> на основе ранее разработанных регрессионных моделей температуры на межфазной границе и износа режущего инструмента сформировать и реализовать подход к многокритериальной оптимизации режимов финишного точения металл-композитной системы, обеспечивающий минимизацию износа инструмента при соблюдении температурных ограничений и требований к качеству поверхности. <bold>Методы и методология.</bold> В качестве методов и методологии исследования использованы ранее разработанные регрессионная модель температуры на межфазной границе типа 2Т3 и модель износа режущего инструмента по типу обобщенного уравнения Фика – Тейлора для твердосплавной пластины AH6225. На их основе сформулирована задача математического программирования с нелинейным температурным ограничением, решаемая методом последовательного квадратичного программирования в заданных диапазонах скорости резания, подачи и глубины резания. <bold>Результаты и обсуждение.</bold> В результате численной реализации предложенного подхода получены области допустимых и рациональных режимов финишного точения металл-композитной системы по критериям термонагруженности и износа инструмента. Показано доминирующее влияние глубины резания на температуру на межфазной границе «металл – металлополимер»; выявлено, что температурное ограничение формирует границы допустимой области режимов; определены сочетания скорости резания, подачи и глубины, обеспечивающие одновременное соблюдение температурного порога металлополимера и приемлемый уровень износа твердосплавной пластины AH6225.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Metal-composite systems</kwd><kwd>Additive manufacturing</kwd><kwd>Metal-polymer composites</kwd><kwd>Cutting temperature</kwd><kwd>Interface</kwd><kwd>Modeling</kwd><kwd>Optimization</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Металл-композитные системы</kwd><kwd>Аддитивные технологии</kwd><kwd>Металлополимер</kwd><kwd>Температура резания</kwd><kwd>Межфазная граница</kwd><kwd>Модель</kwd><kwd>Оптимизация</kwd></kwd-group><funding-group><funding-statement xml:lang="en">Funding This study was supported by grant No. 23-79-10022 from the Russian Science Foundation, https://rscf.ru/project/23-79-10022/ Acknowledgements The study was performed using the facilities of the High Technologies Center of Belgorod State Technological University named after V.G.
