Для решения этой проблемы проанализированы существующие подходы. Предложен новый способ увеличения жёсткости, заключающийся в использовании поддерживающего люнета. Люнет служит дополнительной опорой для фрезы, значительно повышая её жесткость и демпфируя колебания. Приводятся результаты математического моделирования статической жесткости инструментальной системы. Одним из ключевых преимуществ нового подхода является его технологическая простота и возможность интеграции в существующие станки с числовым программным управлением без кардинальной модернизации оборудования. В отличие от активных систем указанный метод не требует сложной электроники или программного обеспечения. Метод позволяет вести обработку глубоких и узких пазов даже при неблагоприятном соотношении их ширины к глубине, что прежде считалось труднореализуемой задачей. Возросшая жесткость системы, в свою очередь, положительно сказывается на износостойкости инструмента и дает возможность увеличить режимы резания, тем самым наращивая общую производительность. Наибольший потенциал метод раскрывает при работе с жаропрочными сплавами, где классическое фрезерование наталкивается на жесткие технологические ограничения.</p></abstract><trans-abstract xml:lang="en"><p>   The article addresses the pressing challenge of machining deep slot grooves and narrow cavities with widths of 3 mm or less in components used in aerospace and power engineering.</p><p>   Particular emphasis is placed on the insufficient rigidity and tendency to vibrate in elongated solid carbide end mills, especially when the length-to-diameter ratio L/D ˃ 5.</p><p>   These vibrations degrade surface quality, accelerate cutting edge wear, induce runout and often lead to tool failure. The authors analyse existing solutions and propose a new method to enhance tool rigidity: the use of a supporting steady rest (steady). This device acts as an additional support for the end mill, significantly increasing its stiffness and suppressing vibrations. The authors present results from mathematical modeling of the static rigidity of the tool system. One of the key advantages of this method is its technological simplicity and the ability to integrate it into existing CNC machines without major equipment overhaul. Unlike active damping systems, the method does not require complex electronics or specialized software. It enables the machining of deep, narrow slots even under highly unfavorable width-to-depth ratios-a task previously considered technologically challenging. Moreover, increased rigidity improves tool life and allows for higher cutting parameters, boosting productivity. This approach is particularly promising for machining parts made from heat-resistant alloys, where conventional milling techniques face significant limitations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>малоразмерная фреза</kwd><kwd>нежёсткий инструмент</kwd><kwd>щелевой паз</kwd><kwd>вибрации</kwd><kwd>жесткость</kwd><kwd>поддерживающая стойка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>small-diameter end mill</kwd><kwd>low-rigidity tool</kwd><kwd>narrow slot</kwd><kwd>vibrations</kwd><kwd>stiffness</kwd><kwd>supporting steady rest</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы не имеют финансовой заинтересованности в представленных материалах и методах</funding-statement><funding-statement xml:lang="en">The authors have no financial interest in the presented materials or methods</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">Altintas Y.
