Considering the current state of scientific and technical knowledge, there is mismatch between size of machine tools used for micro manufacturing and size of the manufactured work pieces. Current machine concepts are derived from scaling conventional components down to cope with increasingly small parts. The aim of this project is to develop innovative direct drives with smart materials. Through the elimination of major parts of the usual drive chain for machine tools, technical and economic advantages can be achieved. The modular shape memory actuators developed in the first funding period can accomplish precise displacements of a few micrometers and can be combined to a machine tool with dimensions of less than half a meter. Because of the drives modular structure, the components can be manufactured and maintained economically. During the second funding period, these drives will be developed further based on the previous findings and new functions will be included. The focus lies on configuring a machine tool out of different modules to gain an improved flexibility. Through choosing suitable components, the machine can be fully customized to fit the machining task at hand. Further developments in the control of shape memory actuators will increase the spectrum of parts which can be produced. Furthermore, extra modules will be added to allow for more degrees of freedom during the manufacturing of complex structures. At the end of the project, all modules will be included in a prototype to validate technical and economic advantages.

考虑到当前的科学技术知识状况，用于微制造的机床尺寸与所制造的零件尺寸之间存在不匹配。目前的机器概念是通过缩小传统部件来处理越来越小的部件而产生的。该项目的目标是利用智能材料开发创新的直接驱动。通过取消机床常用传动链的主要部件，可以获得技术和经济上的优势。在第一个资助期开发的模块化形状记忆执行器可以完成几个微米的精确位移，并可以组合成尺寸不到半米的机床。由于采用模块化驱动结构，因此可以经济地制造和维护部件。在第二个资助期内，将根据以前的调查结果进一步发展这些活动，并将纳入新的功能。重点在于从不同的模块中配置机床，以获得更高的灵活性。通过选择合适的部件，机器可以完全定制以适应手头的加工任务。形状记忆致动器控制的进一步发展将增加可生产的部件的范围。此外，还将增加额外的模块，以便在制造复杂结构时有更多自由度。在项目结束时，所有模块都将包括在样机中，以验证技术和经济优势。
