The research team's principal tasks are the interdisciplinary development, design, and optimization of machine tools as well as the implementation of a methodological approach suitable for these purposes. A focus lies on the examination and optimization of machine tool dynamic behavior. In this regard, methods are developed for the simulation and experimental analysis of machine tool structural behavior, automatic control systems, and cutting processes. In addition, tools and procedures are designed for the development of control software. The control design for complex systems provides an important basis for the development and implementation of integrated adaptive structures and automatic control methods for the improvement of dynamic machine tool properties.

Simulation of Thermal Effects

Heat-intensive manufacturing processes can cause changes in the structural properties of machined parts and components and can have a negative impact on the achievable level of quality. Conversely, the use of resulting process heat holds untapped potential. Nowadays, there is often a lack of sufficient understanding for occurring thermal effects. The Research Area "Simulation of Thermal Effects" is therefore concerned with the structure simulation of thermo-metallurgical and thermo-mechanical phenomena in forming, cutting, and joining manufacturing processes as well as in machine tools. Using numerical methods, the goals here include the analysis and optimization of thermal manufacturing processes and the realization of operational accuracy for machine tools.

Structure and Process Behavior

Modern machine tools are subject to extremely strict requirements with regard to both dynamic properties and machining accuracy. These inherently conflicting requirements are the focus of activities for the Research Area "Structural and Process Behavior." Methods are here developed for the simulation, analysis, and optimization of machine tool structural behavior, automatic controlling, and cutting processes. Methods and tools are also developed here for the analysis and optimization of static, dynamic, and thermal production system behavior while taking machining processes into account. This research is supplemented by close collaboration with the Research Area "Control of Mechatronic Systems" on the subject of control system technology. These methods constitute an important basis for the development and implementation of integrated adaptive structures and automatic control methods by which the dynamic properties of machine tools can be enhanced.

Control of Mechatronic Systems

Modern production facilities are subject to growing requirements and the increasing integration of new functions. The interaction between mechanical, electrical, and information technology modules results in complex mechatronic systems which must be frequently adapted to the unique requirements of individual customers.

In order to develop quality-ensured production systems, the Research Area "Mechatronics" develops methods for describing the dynamic interactions between mechanical structures and electrical drives including underlying control architectures. Other extensively researched areas include process monitoring and quality control. The work here is conducted in close cooperation with the Research Area "Structure and Process Behavior."
