The basic metalworking processes are not likely to change fundamentally, but their organization and control definitely will. 尽管基本的金属加工工艺不太可能发生根本性的改变，但是它们的组织形式和控制方式必将发生改变。 In one respect, manufacturing could be said to be coming full circle. 从某一方面可以说，制造业正在完成一个循环。 * * 《机械工程专业英语教程》 The first manufacturing was a cottage industry: the designer was also the manufacturer, conceiving and fabricating products one at a time. Eventually, the concept of the interchangeability of parts was developed, production was separated into specialized functions, and identical parts were produced thousands at a time. 最初的制造业是家庭手工业：设计者本身也是制造者，一次只构思与加工一个产品。后来，形成了零件的互换性这个概念，生产被依照专业功能分割开来，可以成批地生产数以千计的相同零件。 * * 《机械工程专业英语教程》 Today, although the designer and manufacturer may not become one again, the functions are being drawn close in the movement toward an integrated manufacturing system. 今天，尽管设计者与制造者不再可能是同一个人，但在向集成制造系统前进的途中，这两种功能已经越来越靠近了。 It is perhaps ironic that, at a time when the market demands a high degree of product diversification, the manufacturing enterprises have to increase productivity and reduce cost. Customers are demanding high quality and diversified products for less money. 可能具有讽刺意味的是，在市场需求高度多样化产品的同时，制造业必须提高生产率和降低成本。消费者要求用较少的钱去购买高质量和多样化的产品。 * * 《机械工程专业英语教程》 The computer is the key to meet these requirements. It is the only tool that can provide the quick reflexes, the flexibility and speed, to meet a diversified market. And it is the only tool that enables the detailed analysis and the accessibility of accurate data necessary for the integration of the manufacturing system. 计算机是满足这些要求的关键因素。它是能够提供快速反应能力、柔性和来满足多样化市场的唯一工具。而且，它是实现制造系统集成所需要的、能够进行详细分析和利用精确数据的唯一工具。 《机械工程专业英语教程》 * * It may well be that, in the future, the computer may be essential to a companys survival. Many of todays businesses will fade away to be replaced by more productive combinations. Such more-productive combinations are superquality, superproductivity plants. The goal is to design and operate a pl
