Вибровозбудитель в виде электродвигателя с несбалансированным ротором позволяет моделировать динамическую нагрузку, эквивалентную процессу фрезерования по параметрам модуля сил резания и частоты воздействия, исключая применение СОЖ и стружкообразование. Приведенный метод может быть применен для определения предельных режимов резания и участков рабочей зоны станка, обеспечивающих необходимую жесткость и точность обработки.</p></abstract><trans-abstract xml:lang="en"><p>The article presents a technique for evaluation dynamic flexibility of the vertical milling machine table, considering the deformations of the supporting system of the machine under the influence of forces equivalent to cutting forces. The vibration exciter in the form of an electric motor with an unbalanced rotor makes it possible to simulate a dynamic load equivalent to the milling process in terms of the modulus of cutting forces and impact frequency, excluding the use of coolant and chip formation. A setup has been developed to create an equivalent dynamic load on the machine tool. The proposed technique can be used to determine the cutting limits and the locality of the working area of the machine that provide the greatest rigidity and processing accuracy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>обрабатывающие центры</kwd><kwd>точность обработки</kwd><kwd>точность фрезерования</kwd><kwd>жесткость несущей системы</kwd><kwd>динамика привода</kwd><kwd>ballbar</kwd></kwd-group><kwd-group xml:lang="en"><kwd>CNC machine tools</kwd><kwd>milling accuracy</kwd><kwd>supporting system rigidity</kwd><kwd>feed drive system dynamics</kwd><kwd>ballbar</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Luo B.
