Отмечено, что дальнейшее повышение объёмной точности путём совершенствования конструкции и повышения качества изготовления деталей станков в настоящее время практически невозможно, и прогресс в этом направлении связан с программной коррекцией движений рабочих органов с помощью различных математических моделей. На основе ранее представленной авторами модели измерений и вычислений объёмной геометрической погрешности станков разработана процедура коррекции перемещений рабочего органа трёхкоординатного металлорежущего станка. Процедура позволяет значительно повысить точность позиционирования рабочего органа трёхкоординатного металлорежущего станка – точность его выведения в заданную точку. При управлении движением рабочего органа использованы астатический закон и результаты вычислений координат точек траектории, скорректированных согласно дифференциально-геометрической модели объёмной погрешности. Разработанная процедура реализована программно и позволяет вносить коррекцию в управляющую программу, представленную в виде G-кода. Приведены результаты экспериментов по программной коррекции объёмных погрешностей трёхкоординатного металлорежущего станка с числовым программным управлением в соответствии с предложенной процедурой. Эксперименты выполнены в Московском государственном технологическом университете «СТАНКИН». По итогам программной коррекции значительно (на 90 %) уменьшена геометрическая объёмная погрешность станка. Разработанную процедуру можно применять для повышения точности металлорежущих станков путём создания постпроцессоров, которые на основе результатов интерферометрических измерений вычисляют скорректированные координаты точек траектории рабочего органа, заданные в системе управления.</p></abstract><trans-abstract xml:lang="en"><p>The article is devoted to increasing the volumetric accuracy of multi-axis machine tools. Based on the model of measurement and calculation of the volumetric geometric error of machine tools presented by the authors, a method has been developed which allows to signifi cantly improve the accuracy of the movement of the operating unit of a three-axis metal-cutting machine tool to a given point. The astatic law and the calculation of the coordinate correction according to the differential geometric model of the volumetric error are used to control the movement of the operating unit. The developed method is implemented programmatically and allows to perform the correction in the control program represented in G-code. As a result of experiments on software correction of volumetric errors according to the developed method, conducted at the State Engineering Centre of the Moscow State University of Technology “STANKIN” on a threeaxis CNC machine tool, a signifi cant reduction (up to 90 %) of geometric volumetric errors was shown. The developed method can be used to improve the accuracy of metal-cutting machine tools by creating postprocessors that calculate corrections to the coordinates set in the control system based on the results of interferometric measurements.</p><p>Keywords: volumetric accuracy, interference measurements, three-axis machine tools, machine tool accuracy, geometric errors, astatic control law, mathematical modelling, differential geometry</p></trans-abstract><kwd-group xml:lang="ru"><kwd>объёмная точность</kwd><kwd>интерференционные измерения</kwd><kwd>трёхкоординатные металлорежущие станки</kwd><kwd>точность станочного оборудования</kwd><kwd>геометрические погрешности</kwd><kwd>астатический закон управления</kwd><kwd>математическое моделирование</kwd><kwd>дифференциальная геометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>volumetric accuracy</kwd><kwd>interference measurements</kwd><kwd>three-axis machine tools</kwd><kwd>machine tool accuracy</kwd><kwd>geometric errors</kwd><kwd>astatic control law</kwd><kwd>mathematical modelling</kwd><kwd>differential geometry</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства науки и высшего образования Российской Федерации (проект FSFS-2021-0003).</funding-statement><funding-statement xml:lang="en">The work was supported by the Ministry of Science and Higher Education of the Russian Federation (project no.
