随着微流控、微机械、微电子和微光学系统功能集成度的提高，工件尺寸不断缩小，复杂程度不断增加，对加工精度提出了更高的要求。在工艺和几何参数方面，大多数精加工制造工艺都可以通过三轴或五轴的铣削和磨削操作来完成。但是，尽管现有的机床很难在所有自由度上实现所需的过程动态和精度，但要求仍然增加。因此，Fraunhofer IPT开发了高精度机床，遵循紧凑的设计策略，尽可能减少传统机床部件（如测量或驱动系统）的整体尺寸。两个紧凑型机床的发展表明，通过紧凑的设计提高了动态和精度，并在下面进行描述。
Due to raising functional integration in micro fluidic, micro mechanic, micro electronic and micro optical systems the trend to scaling down the work piece sizes while increasing its complexity requires high precise machine accuracy. With respect to the process and geometrical parameters, most of the finishing manufacturing processes can be covered by milling and grinding operations with three or five machine axes. But whereas the available machine tools hardly achieve the required process dynamic and accuracy in all degrees of freedom, the requirements still increase. For this reason the Fraunhofer IPT has developed high precise machine tools following a compact design strategy by reducing the overall machine dimensions as far as conventional machine components such as measuring or drive systems were available. The developments of two compact machine tools exemplify the dynamic and accuracy enhancement by compact design and are described in the following.
