Optimization of machining parameters for ball-end milling Год выпуска: 2011Автор: Jackson G. Njiri,Bernard W. Ikua and George N. NyakoeИздательство: LAP Lambert Academic PublishingСтраниц: 108ISBN: 9783846500040Описание This work describes the optimization process for ball-end milling of sculptured surfaces such as those encountered in dies/moulds and aircraft structural components. Since cutting forces are the main factors governing machining accuracy, machine tool vibration, power requirements and tool life, a comprehensive methodology of modelling, analysis and control of cutting forces is outlined. Due to complexity and vagueness of manufacturing process, fuzzy logic controller is employed to vary cutting parameters in real-time during manufacturing process depending on the emanating cutting forces. The control scheme aims at maximizing on the material removal rate and at the same time reducing on the rate at which the tool wears out. Also the need to have a constant machine operator to supervise the machining process is elimintated.

Olga Огромное Вам спасибо за рефераты, я сегодня их забрала и прочитала, в понедельник поедем сдавать в экстернат. Не могу не сказать Вам, что Вы очень талантливый и тонкий человек. Я хорошо знаю, что образование, каким бы качественным оно не было, не даёт возможности безошибочно почувствовать поставленную задачу. Высокое качество Ваших работ бесспорно, однако меня больше всего поразила точность и артистичность не просто реализации цели и задач исследования, а исполнения специалистСКОЙ по духу работы: в нашем случае это не просто рефераты на заданную тему, а рефераты совершенно определённого качественно (в смысле возраста, уровня образования и т.п.) специалиста. Выражаю Вам своё восхищение, надеюсь на дальнейшее сотрудничество.
