The method of measuring tool life in this work is in accordance with ISO3685 tool life testing standard for single point turning tool. The present work deals with, experimental investigations to understand the role of cryogenic treatment, on tool wear mechanism and dimensional variations in machining of crank shaft as a case study. Commercially in machining of crankshaft, tungsten carbide and HSS tools are used. The tool life results have been compared with treated and untreated tools. Further the result of study suggests that tool life of tungsten carbide inserts increases by 22%. Cutting conditions like feed, depth of cut and geometry of tools were held constant throughout the experimental study. After the cryogenic treatment of tools, machining cost per component has been reduced by 14. 75%. The best settings of parameters for CNC machine are cutting speed 290m/min for roughing and finishing tool, 280m/min for facing tool. For HSS tools result indicates that tool life improves by 20%.

Кроме того, закон определяет порядок использования финансовых средств, высвобождаемых от налогооблажения и предоставления соответствующих отчетов. О потенциале производственного комплекса Курской области достаточно красноречиво говорят цифры – Курская область экспортирует свою продукцию в 52 страны мира. Она производит 1/6 электроэнергии, почти столько же сахара, более четрверти железнорудных окатышей, пятую часть аккумуляторов, каждый десятый подшибник. Взяв инвестиционный страрт всего около 2-х лет назад , администрация области провела активную работы с инофирмами по организации совместных производств. Комитет внешнеэкономической деятельности областной администрации сотрудничестве с отраслевыми комитетами и курскими предприятиями осуществляет планомерное привлечение инвестиционных и кредитных ресурсов для реализации проектов на основе динамичного и сбалансированного развития экономики области. Пакет прорабатываемых проектов включает около сорока предложений. Общая сумма привлекаемых инвестиционных и кредитных ресурсов составляет 800 -1000 млн. долл. США. Основные усилия были направлены но переоснащение сельского хозяйства современными тракторами фирмы ZA ELLO (Аргентина), сельскохозяйственными машинами фирмы KVER ELA D (Норвегия) и зерноуборочными, свеклоуборочными и картофелеуборочными комбайнами фирм JOH DEERE и CASE (США), GLAAS (Германия), EW HOLLA D (Бельгия).
