SPP 1156: Adaptronics for Machine Tools

优先方案的核心是提高机床的效率。高效机床的特点是产品质量高，加工速度快，使用不同的刀具或材料时，可靠性和灵活性强。尽管子组件(结构、执行器、测量系统等)在目前不断改进的情况下，只有通过根本的创新优化思想才能预期效率的提高。一个例子是“智能结构”，也被称为自适应电子学，到目前为止，它主要是为了航空航天技术而开发的。自适应电子元件，如压电多层陶瓷，可以完全集成在一个结构中，可以测量结构的振动和结构产生的噪声，以及抑制或完全消除它们。因此，新的模块化机械部件被开发出来，通过这些部件，结构可以作为一个整体或作为最佳的独立机械部件来布置。通过自适应电子组件也可以补偿具有长期效应或其他(准)静态效应的热变形，这些效应也会对产品质量产生负面影响。结构力学领域的工程师、控制工程师和生产工程师必须共同努力，才能针对不同的制造过程和不同的机械和工艺相关问题进行自适应电子组件的理论和实验研究。这种跨学科的协同作用是成功开发具有结构集成执行器和传感器与自适应控制算法相结合的机床最优机械结构系统的不可或缺的基础。

In the centre of the Priority Programme is the increase of efficiency of machine tools. An efficient machine tool is characterized by a high production quality and fast machining speeds, reliability and flexibility when different tools or materials are used. Although sub-assemblies (structures, actuators, measuring systems, etc.) are at the moment continuously improved, improvements in efficiency can be expected only through fundamental innovative optimization ideas. An example are "smart structures", also called adaptronics, which until now were developed predominantly for aerospace techniques. With adaptronic components, like piezoelectric multilayer ceramics, which can be completely integrated in a structure, it is possible to measure vibrations and structure-born noise of structures, as well as to damp or completely eliminate them. Thus new modular machine components are developed, through which the structure can be laid out either as a whole or as optimal stand-alone machine components. Through adaptronic components can be compensated as well thermal deformations with long-time effects or other (quasi-)static effects that also affects in a negative way the production quality. For theoretical and experimental researches on adaptronic sub-assemblies for various manufacturing processes with different machine and process related questions, engineers of the structural mechanics field, control engineers and production engineers have to work together. This interdisciplinary synergy is an indispensable foundation for a successful fundamental development of optimal mechanical structure systems for machine tools with structure-integrated actuators and sensors combined with adaptive control algorithms.
