SPP 1156: Adaptronics for Machine Tools

优先计划的核心是提高机床的效率。高效机床的特点是生产质量高，加工速度快，在使用不同的刀具或材料时具有可靠性和灵活性。虽然子组件（结构、执行器、测量系统等）目前正在不断改进，但效率的提高只能通过根本性的创新优化思想来实现。一个例子是“智能结构”，也称为自适应电子学，到目前为止主要是为航空航天技术开发的。使用自适应元件，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，以及阻尼或完全消除它们。因此，开发了新的模块化机器组件，通过它可以将结构布置为整体或最佳的独立机器组件。通过自适应元件也可以补偿长时间影响的热变形或其他（准）静态影响，这些影响也以消极的方式影响生产质量。结构力学工程师、控制工程师和生产工程师必须共同努力，对具有不同机器和工艺相关问题的各种制造工艺的自适应电子子组件进行理论和实验研究。这种跨学科的协同作用是成功开发具有结构集成致动器和传感器与自适应控制算法相结合的机床最佳机械结构系统的必要基础。

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.
