3D моделирование оптимального затылования дисковых модульных фрез
Ажар, А. В.; Осадчий, Е. Н.; Ишкуло, П. Ю. (БНТУ, 2021)It is proposed to determine the optimal diameter of the grinding wheel for sharpening shaped disk modular cutters by 3D modeling of the grinding operation, taking into account the restrictions on the formation of a saddle on a sharpened tooth and grooves on an adjacent tooth. Analysis of the results of modeling the sharpening operation of standard cutters with a modulus of m = ...2022-03-03 -
3D моделирование технологии затылования дисковых зуборезных фрез
Ажар, А. В.; Дулуб, А. Д.; Кустов, С. В.; Минасян, Г. О. (БНТУ, 2022)3D modeling was carried out to determine the optimal diameters of grinding wheels for backing the back surface of the tooth of a disk gear cutter with a module m = 1...16 mm. A linear relationship has been established between the height of the tooth, the angle of the flute of the cutter and the diameter of the grinding wheel. It has been proven that the formation of a “saddle” ...2023-01-24 -
Автоматизация подбора гитары сменных зубчатых колес на универсально-фрезерный станок
Ажар, А. В.; Сивак, М. В. (БНТУ, 2023)The article describes a developed software module for automating the selection of replacement wheels for a guitar used on a universal milling machine. The module is implemented in MS Excel based on a macro command, the algorithm of which sequentially goes through all the options from a given set of wheels to find the optimal solution. The module can be adapted to various CAD ...2024-01-23 -
Анализ эффективности обработки крепежных отверстий на станке с ЧПУ комбинированными инструментами
Ажар, А. В.; Шейбак, Д. В. (БНТУ, 2020)It is proposed to use the possibilities of kinematics of modern CNC machines to expand the scope of combined and multifunctional processing. A project is proposed for machining fastening holes in the "Bracket" part of a MAZ car on a 4-axis machining center with combined tools. Achieved reduction of the nomenclature of tools, piece time and unit power by more than 2 times. A model ...2021-01-26 -
Оптимизация операции заточки затылованных дисковых фасонных фрез методами компьютерного 3D моделирования
Ажар, А. В.; Минасян, Г. О.; Кошевой, А. Н. (БНТУ, 2020)A method is proposed for determining the optimal diameter of a grinding wheel for sharpening shaped disk mills, based on computer 3D modeling of the grinding operations, taking into account the restrictions on the formation of a saddle on a tooth and a gouge on an adjacent tooth. For the feasibility study of the wheel toolkit at the stage of production preparation, a complex ...2021-01-26 -
Оценка ресурса сборного комбинированного инструмента по временной стойкости и количеству обработанных отверстий
Ажар, А. В.; Дулуб, А. Д.; Сивак, М. В. (БНТУ, 2023)An example is given of calculating the service life of a combined tool for machining a stepped hole, which proves the inappropriateness of assigning tool cutting modes to a cutting element with a minimum minute resource. It is proposed to pre-assign cutting modes for tools of the same type according to the cutting element with the longest cutting length, establishing a replacement ...2024-01-23 -
Решение проблем инструментального производства при проектировании сложнопрофильных фасонных и сборных инструментов методом 3D-моделирования
Ажар, А. В.; Пенкина, А. Д. (БНТУ, 2020)It is proposed to use the methods of computer 3D modeling to solve the problems of manufacturing complex shaped tools that work by copying when processing cylindrical, screw surfaces, and prefabricated tools with spatial basing of a removable polyhedral plate.2021-01-26 -
Структурная модель и расчет показателей надежности сборных торцовых фрез
Ажар, А. В.; Верхотуров, А. Д. (БНТУ, 2021)The cutter body and the insert holding mechanism are highly reliable elements that have a probability of failure-free operation close to unity in the period of time before the tool stops. The reliability of the cutter is assessed by the reliability of its inserts (cutting part), which often fail due to breakages and chipping. The assembled face milling cutter has a reliability ...2022-03-03
