This collaborative research project is directed towards a new technology for the production of micro/meso-scale components by methods whose efficiency approaches that of mass production. Key to achieving this capability will be the creation of "miniaturized" machine tool systems (referred to as meso-Machine Tools, mMTs) whose volume is on the order of 1 dm3. These systems are required to meet the rapidly growing demand for 3D parts and part features at the micro/meso-level (0.01 - 10.00 mm range) in materials that include stainless steel, titanium, aluminum, platinum, iridium and others is currently being met by using ultra-precision CNC machine tools. It is common to have machine-to-workpiece volume ratios of 106 or higher at best, a situation that adversely affects accuracy, precision and overall efficiency. The prevalent microelectronic fabrication techniques and their spin-offs used for micro-electromechanical systems (MEMS) are, in turn, are limited by their inability to produce arbitrary 3D features in a wide range of materials and by their limited relative accuracy. However, to their advantage, MEMS-based technologies are batch type, leading to cheap mass production, while ultra-precision CNC processes are serial, inherently expensive and not easily adaptable to mass production.The goal is to meet productivity requirements by applying these mMT in a massively parallel fashion. It is envisioned that the mMTs, in analogy to a computer system, will be equivalent to plug-and-play boards and treated as replaceable entities. To facilitate an integration of such machines into a system, resource and information distribution mechanisms will be established by an architecture, similar in concept to the "bus" of a computer, that supplies energy, control/feedback information, and materials and tools to/from the individual machines. It is anticipated that the project will demonstrate that it is possible to build mMT systems for costs two or three orders of magnitude below existing systems.

该协作研究项目针对一种新技术，用于通过其效率接近大众生产的方法来生产微/中尺度的组件。 实现此功能的关键将是创建“微型”机床系统（称为中摩希型工具，MMTS），其音量为1 dm3。 这些系统需要满足对3D零件的快速增长需求以及在包括不锈钢，钛，铝，铂金，iRidium等的材料中，在微型/中级级别（0.01-10.00 mm范围内），目前通过使用Ultra Ultra Ultra cnc机械工具来满足，包括不锈钢，钛，铝，铂金，iRidium等。通常，机器对工作量的体积比最多为106或更高，这种情况会对准确性，精度和整体效率产生不利影响。流行的微电子制造技术及其用于微电机电系统（MEMS）的衍生产品又受到其无法在广泛的材料中产生任意3D特征的限制，并且其相对精度有限。但是，为了他们的优势，基于MEMS的技术是批处理类型，导致廉价的批量生产，而超精确的CNC流程是串行的，固有的昂贵且不容易适应大众生产。其目标是通过以众多并行方式应用这些MMT来满足生产力要求。可以预见的是，与计算机系统相比，MMT等于插入板，并被视为可替换实体。为了促进此类机器将这些机器集成到系统中，资源和信息分配机制将由架构建立，概念与计算机的“总线”相似，该计算机的“总线”提供了能源，控制/反馈信息以及材料和工具到各个机器的材料和工具。预计该项目将证明可以构建MMT系统以低于现有系统的价格为两个或三个数量级。
