Объектом исследования являются процессы и закономерности обеспечения безприжогового (бездефектного) шлифования деталей, изготавливаемых из труднообрабатываемой коррозионностойкой нержавеющей стали марки 12Х18Н10Т, никелевого сплава марки ХН60ВТ, конструкционной стали марки 30ХГСА и сложнолегированной стали марки 12Х2НВФА. В работе использовано имитационное моделирование в программной среде DEFORM. В качестве критерия, регламентирующего обеспечение качественных показателей процесса шлифования, была выбрана температура в зоне резания. Исследования базируются на использовании положений теории резания материалов. Установлено, что каждый из исследованных абразивных инструментов 1 25A F60 O6V, 1 25A F60 Q6V, 1 25A F80 O6V, 1 25A F80 N7V имеет свою рациональную область применения. Для детали «Штырь» экономический эффект, достигнутый за счет исключения брака деталей, вызванного возникающими прижогами на шлифуемой поверхности, составил 18095 руб. С позиций повышения качества обработанной поверхности детали по шероховатости на основе анализа параметра Ra рационально применение малых глубин резания (от 0,05 мм до 0,25 мм) в сочетании с применением частот вращения ведущего круга до 108 мин-1. С позиций обеспечения требуемой точности изготовления детали показано, что целесообразно применение глубин резания до 0,25 мм в сочетании с применением частоты вращения ведущего круга 86 мин-1. Таким образом, разработаны новые концептуальные принципы и методология проектирования (и выбора) абразивных инструментов с обеспечением минимального разупрочнения материала шлифуемой детали, обеспечения требуемой шероховатости поверхности, точности размеров детали и производительности обработки. Дальнейшее развитие работы целесообразно вести с привлечением более крупнозернистых (F40, F36) абразивных инструментов.</p></abstract><trans-abstract xml:lang="en"><p>The present work is aimed at enhancing the grinding efficiency of abrasive tools by designing and selecting their optimal characteristics. To that end, regularities in the process of defect-free grinding of workpieces made of hard-tomachine corrosion-resistant stainless steel of 12Х18Н10Т grade, nickel alloy of ХН60ВТ grade, structural steel of 30ХГСА grade, and complex-alloyed steel of 12Х2НВФА grade are studied by simulation modeling in the DEFORM software environment. The temperature in the cutting zone is selected as a criterion determining the quality indicators of the grinding process. The research methodology is based on the theory of metal cutting. It was established that each of the investigated abrasive tools, i.e., 1 25A F60 O6V, 1 25A F60 Q6V, 1 25A F80 O6V, and 1 25A F80 N7V is characterized by its rational field of application. For the “Pin” workpiece, the economic effect achieved due to elimination of scrap caused by grinding burns on the ground surface amounted to 18,095 RUB. In terms of the Ra parameter, an improved roughness of the machined surface can be achieved by small cutting depths (from 0.05 mm to 0.25 mm) in combination with a driving wheel speed of up to 108 min-1. The required accuracy of machining can be achieved by cutting depths of up to 0.25 mm in combination with a driving wheel speed of 86 min-1. Hence, a new methodology for designing and selection of abrasive tools is proposed. This methodology ensures minimal softening of the ground material, as well as the required surface roughness, accuracy of workpiece dimensions, and machining performance. In future research, coarser-grained (F40, F36) abrasive tools should be investigated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>абразивный режущий инструмент</kwd><kwd>бесцентровое шлифование</kwd><kwd>температурный параметр процесса шлифования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>abrasive cutting tools</kwd><kwd>centerless grinding</kwd><kwd>grinding temperature parameter</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">Непогожев А.А., Желтухин А.В., Крит Б.Л., Морозова Н.В., Эпельфельд А.В., Перетягин П.Ю.
