In the paper there is investigated the cutting tool properties of high-strength composite ceramics with multi-coated cutting hardened steel. Mathematical models of cutting are obtained. They establish the dependence of the wear and tear on the back of the instrument, roughness of the machined surface of the parts, the tangent component of the cutting forces, as well as cutting power on the modes of turning. A problem of cutting tools modes optimization is made of high-strength composite ceramics. It is established that the application of the multi-functional coatings on ceramic cutting tool allows you to increase the efficiency of processing.
Исследованы режущие свойства инструмента из высокопрочной композиционной керамики (ВКК) с многофункциональным покрытием при резании закаленной стали. Получены математические модели резания, устанавливающие зависимости износа по задней поверхности инструмента, шероховатости обработанной поверхности детали, тангенциальной составляющей силы резания, а также мощности резания от режимов точения. Сформулирована и решена задача оптимизации режимов резания инструментом из ВКК. Установлено, что нанесение многофункциональных покрытий на керамический режущий инструмент позволяет повысить эффективность обработки.
