美国可加工性数据中心(MDC),是美国国防部管辖的若干情报分析中心之一,自1964年与国防部签订合同后,一直由金属切削联合研究公司管理。金属切削加工在美国是一个非常庞大的行业,现在大约有230万台金属切削机床正在投入使用,其中有5万台是数控机床。每年的刀具费用在19.25亿美元以上,切削液费用在16亿美元以上(机械加工),在劳工和杂费上的费用估计每年是1150亿美元。这样大的消耗,使降低成本具有很大的潜力,
The US Machinability Data Center (MDC), one of several intelligence analysis centers under the control of the U.S. Department of Defense, has been managed by the Metal Cutting Joint Research Company since its contract with the Department of Defense in 1964. Metal cutting is a very large industry in the United States. About 2.3 million metal cutting machines are currently in operation, 50,000 of which are CNC machines. Annual tool costs above $ 1.925 billion, cutting fluid costs above $ 1.6 billion (machining), labor and miscellaneous fees are estimated at $ 115 billion a year. Such a large consumption, so that there is great potential to reduce costs,
