По разработанным маршрутам холодной прокатки в сочетании с термической обработкой листов из алюминиевого сплава 8011А получены образцы с различными коэффициентами поперечной деформации. Рассчитано усредненное значение показателей анизотропии в плоскости листа и коэффициент плоскостной анизотропии. На специальном стенде, состоящем из промышленного робота KR 160 R1570 nano, рамы для фиксации заготовки и бесконтактной оптической системы измерения деформаций Vic 3D, получены значения предельного угла инкрементального формообразования. На основании полученных значений были построены зависимости распределения главных деформаций e1 и e2 в направлении прокатки по образующей для листов с различными показателями анизотропии. Определено, что характер распределения деформации одинаков для рассматриваемых образцов. От центра к краю заготовки деформации увеличиваются до предельной величины (участок криволинейной образующей), а затем уменьшаются до нуля (область перехода от образующей ко дну). Однако, главные деформация и положение максимума для листов с показателем анизотропии Δμ &gt; 0 выше, чем для листов с Δμ &lt; 0. Затем для изготовленных листов был определен предельный угол инкрементального формообразования, равный 67,8º для образцов с положительным показателем плоскостной анизотропии и 47,6º для образцов с отрицательным. Полученные результаты в совокупности с положением трещины на конических деталях свидетельствуют о существенном влиянии анизотропии механических свойств на процесс инкрементального формообразования</p></abstract><trans-abstract xml:lang="en"><p>The results of an experimental study of the effect of anisotropy of the mechanical properties of sheet blanks on the limiting angle of incremental shaping are presented. According to the developed cold rolling routes in combination with heat treatment of aluminum alloy 8011A sheets, samples with different coefficients of transverse deformation were obtained. The average value of the anisotropy indicators in the plane of the sheet and the coefficient of planar anisotropy are calculated. The values of the limiting angle of incremental shaping were obtained on a special stand consisting of an industrial robot KR 160 R1570 nano, a frame for fixing the workpiece and a non-contact optical deformation measurement system Vic 3D. Based on the obtained values, the dependences of the distribution of the main deformations e1 and e2 in the direction of rolling along the generatrix for sheets with different anisotropy indices were constructed. It is determined that the nature of the strain distribution is the same for the samples under consideration. From the center to the edge of the workpiece, the deformations increase to the maximum value (the section of the curved generatrix), and then decrease to zero (the transition area from the generatrix to the bottom). However, the main deformation and the position of the maximum for sheets with an anisotropy index Δμ &gt; 0 is higher than for sheets with Δμ &lt; 0. Then, for the manufactured sheets, the limiting angle of incremental shaping was determined, equal to 67.8° for samples with a positive index of planar anisotropy and 47.6° for samples with a negative one. The obtained results, together with the position of the crack on the conical parts, indicate a significant influence of the anisotropy of mechanical properties on the process of incremental shaping.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инкрементальное формообразование</kwd><kwd>предельные деформационные возможности</kwd><kwd>алюминиевый сплав 8011А</kwd><kwd>анизотропия механических свойств</kwd></kwd-group><kwd-group xml:lang="en"><kwd>incremental forming</kwd><kwd>ultimate deformation capabilities</kwd><kwd>aluminum alloy 8011А</kwd><kwd>anisotropy of mechanical properties</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования выполнены при поддержке гранта Президента МД-936.2022.4.</funding-statement><funding-statement xml:lang="en">the author expresses gratitude for the financial support of the research to the grant of the President MD-936.2022.4.</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">Кривошеин В.А., Анцифиров А.А., Май-стров Ю.В.
