A typical RMS includes both conventional flexible machines and a new type of machine called the reconfigurable machine tool (RMT) on its production line。 The mechanical wrenches in Figure 1 help illustrate the RMT concept。

Figure 1: Reconfigurable tools fill the gap between dedicated tools and flexible tools [1]

Therefore, in RMS, reconfigurable machine tool (RMT) is designed to be easily reconfigured such that they process a family of parts and accommodate new and unanticipated changes in the product design and processing of reconfiguration, new modules replace some old modules, and the degree of freedom of the machine tool are also changed。 Thus, RMT undergo topological changes, i。e。, size, type and number of modules and their interconnections。 [13]

The main advantage of this new approach is the customized flexibility of the system to produce a “part family” of products with lower investment cost than FMS。 A set of core characteristics: modularity, scalability, integrability, convertibility, customization and diagnosibility comprise the heart of an RMS。

There is no milling machine that has yet been constructed suitable for all classes of work。 The Reconfigurable Machine Tool (RMT) (showed in Figure 2) was invented in 1999 in the Engineering Research Center (ERC) for Reconfigurable Manufacturing Systems (RMS) at the University Of Michigan College Of Engineering。 This research is focused on the rapid change of manufacturing process requirement, which makes it possible to quickly adjust its production capacity and functionality within a part family in response to sudden market changes an intrinsic system change。 [4]摘要

当今工业市场竞争激烈，产品寿命短，客户需求变化迅速，形成了新的制造 系统的大趋势。可重构机床（RMT）是一种对未来加工系统的解决方案，这样不 仅可以提供定制的解决方案，使用要求也很划算。本文旨在建立和实施制造业 RMT 设计方法。该方法被引入和扩展，根据五个原则的模块化机床设计。该方法 将在这里一步一步被应用，使方法更清晰。 首先是从客户那里获取概念或过程 要求。客户需要三个可重构零件的高速铣削应用的部件族，包括表，主轴和刀具。 在这种情况下，为了满足客户的要求和概念，双主轴（刀具）可作为一个例子来 解释 RMT 设计方法。其次，在组合机床设计方法中最重要的一点是分析的四原则， 模块化设计，以丰富的经验为基础的有价值的建议。这项工作的四个原则，分离， 统一（标准化），连接和适应，实用的设计方法。在经典四原则的基础上，考虑 零浪费概念，可重用性原则是一个附加原则。为了有效地进行 RMT 设计方法和部 件族的重构，重构的优点在双主轴 RMT 设计根据 RMT 设计方法的补充是有必要的。 最后一步利用计算机软件模拟 3 个维度的配置。可以估算讨论自由度（DOF），刚 度分析和模块的数量。
