Annotation
В первом, на основе чертежа детали и условии среднесерийного производства, были выполнены следующие действия: произведен анализ исходных данных; осуществлен подбор оптимального вида заготовки; разработан технологический процесс изготовления детали; подобрано подходящее оборудование, инструмент и оснастка; расcчитаны режимы резания и нормы времени; составлена техническая документация. Во втором разделе было спроектировано приспособления, а именно: самоцентрирующиеся тиски с пневматическим приводом, для фрезерно-центровальной операции. Были реализованы следующие задачи: рассчитаны силы резания; подобраны установочные элементы; рассчитаны сил зажима; подобрано зажимное устройство; рассчитан и подобран силовой привод. В третьем разделе производилось проектирование трех видов инструмента, а именно: фасонного призматического резца; червячной фрезы для нарезания цилиндрических зубчатых колес; комплекта метчиков.
In the first, based on the drawing of the part and the condition of medium-scale production, the following actions were performed: the analysis of the initial data was performed; the selection of the optimal type of workpiece was carried out; the technological process of manufacturing the part was developed; suitable equipment, tools and accessories were selected; cutting modes and time standards were calculated; technical documentation was compiled. In the second section, devices were designed, namely: self-centering vise with pneumatic drive, for milling and centering operations. The following tasks were implemented: the cutting forces were calculated; the mounting elements were selected; the clamping forces were calculated; the clamping device was selected; the power drive was calculated and selected. In the third section, three types of tools were designed, namely: a shaped prismatic cutter; a worm cutter for cutting cylindrical gears; and a set of taps.
