При разработке методики предварительного расчета суммарной осевой силы, действующей на режущей кромке концевых фрез, использованы структурные схемы механообработки и силовые модели процессов косоугольного резания в режимах осевой подачи инструмента и непрерывного пластического деформирования обрабатываемого материала. Опыты с вращающимся инструментом проведены на 3-осевом обрабатывающем центре UWF 1202 H фирмы «Hermle», дополненном пьезоэлектрическим динамометром фирмы «Kistler» (модель 9272). Предложена, разработана и апробирована методика предварительного расчета силовых характеристик процесса механической обработки заготовок концевыми фрезами, учитывающая влияние величины энергетической мощности вязкого разрушения обрабатываемого материала. Обусловлено, что контактное трение, возникающее на передней и задней поверхностях режущего инструмента, не достигает предельной величины и подчиняется закону Кулона-Амонтона, то есть оценивается зависимостью прямо пропорциональной нормальному давлению. В результате выполненных вычислений предопределены материалы заготовки для фрезерной обработки – сталь 45 (AISI 1045), и концевой двузубой фрезы – сплав Т14К8 без покрытия, из которого были изготовлены опытные образцы. Установлены режимы фрезерной обработки: глубина засверливания – 4 мм; скорости резания – 50, 100 и 150 м/мин; подача режущего инструмента – 0,05 и 0,1 мм/об. Выявлено, что отклонение измеренных значений осевой силы резания от расчетных в диапазоне изменения значений скорости подачи инструмента составляет не более 11%, а в диапазоне изменения значений скорости резания не более 15%. Разработанная расчетно-аналитическая методика оценки силовых параметров процесса формообразования заготовок концевыми фрезами обеспечивает повышение оперативности и достоверности предварительного прогностического расчета рабочих параметров и характеристик режущих элементов концевых фрез.</p></abstract><trans-abstract xml:lang="en"><p>The aim is to develop and validate an operational methodology for calculating the force parameters and characteristics of the tool and the process of milling structural materials with end milling cutters. The structural schemes of machining and force models of oblique cutting processes in the modes of axial tool feed and continuous plastic deformation of the processed material were used when developing the method of preliminary calculation of the total axial force working on the cutting edge of end milling cutters. The rotating tool tests were conducted on a Hermle UWF 1202 H 3-axis machining center supplemented with a Kistler piezoelectric dynamometer (model 9272). Authors suggested, developed and tested the preliminary calculation method applied to the force characteristics of the machining process of workpieces by end milling cutters, considering how the energy power of ductile fracture of the machined material affects the process. Contact friction arising on the front and rear surfaces of the cutting tool does not reach the limiting value being subject to the Coulomb – Amonton law, that is, it is estimated by the dependence directly proportional to the normal pressure. After calculations, we defined the materials of the workpiece for milling, that is 45 steel (AISI 1045), and the end two-tooth cutter, uncoated T14K8 alloy, which was used to produce samples. The following milling modes were established: 4 mm boring depth; 50, 100 and 150 m/min cutting speeds; 0.05 and 0.1 mm/rev cutting tool feed. Deviation of the measured values of axial cutting force from the calculated values in the range of changing values of tool feed rate was found to be no more than 11%, and in the range of changing values of cutting speed no more than 15%. The developed calculation and analytical methodology for estimating force parameters of the machining process by end milling cutters provides an increase in the efficiency and reliability of the preliminary prognostic calculation of operating parameters and characteristics of cutting elements of end milling cutters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фрезерная обработка</kwd><kwd>концевые фрезы</kwd><kwd>косоугольное резание</kwd><kwd>деформационное упрочнение</kwd><kwd>Кулоново трение</kwd><kwd>удельная работа разрушения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>milling</kwd><kwd>end mills</kwd><kwd>oblique cutting</kwd><kwd>strain hardening</kwd><kwd>Coulomb friction</kwd><kwd>specific work of fracture</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания в сфере научной деятельности Министерства науки и высшего образования Российской Федерации (тема FZUN-2020-0015, госзадание ВлГУ).</funding-statement><funding-statement xml:lang="en">The research was carried out under the state assignment in the field of scientific activity of the Ministry of Science and Higher Education of the Russian Federation (theme FZUN-2020-0015, state assignment of Vladimir State University).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Jawahir I.S., Schoop J., Kaynak Y., Balaji A.K., Ghosh R., Lu T.
