An issue people all around the world are faced with is the reduction of climate-changing emissions of greenhouse gasses. By reducing the weight of moving components, especially during the transportation process, using massive amounts of resources can be saved, and the CO2-emissions can be reduced. Lightweight constructions belong to one of the drivers of innovation within Europe and are recognised as a critical technology in politics and industry. Efficient, lightweight construction solutions use synergetic combinations of different materials. At the moment, the processing operations are separated from each other, whereby separate work stages and extensive joining technology have to be applied. The vision of the excellence clusters ist he merging of high volume production suitable basic technology for the efficient resource production of lightweight constructions with high power and functional density.
Immense energy and material savings distinguish this kind of technology fusion. With lightweight constructions, efficient use of materials is given, which when used with mobile applications naturally reduces the usage and CO2 emissions. By doing so, the excellence cluster pursues the long term strategy of the so-called bivalent resource efficiency (BRE-Strategie). This requires close cooperation of engineers and natural scientist on the one hand and technological and selections oriented professional disciplines on the other.Open Homepage
Chipping production still requires greater accuracy and high productivity. The excellent control over the structural design of the structures of the machines and the well-advanced servo technology of the feed axis already contribute to a high precision. Ever growing production volume requires more significant prime movers and high feed rates. In the case of the main drivers, in principle, they mostly dissipate in heat convection at the knitting point of the chipping process and in case of feed drivers, their diversion over either the heightened frictional powers of the mechanical driver and guiding elements or heightened power losses of the driving feeds themselves produces heightened heat convection as well. Both processes increase thermo-elastic deformations.
Conventional measures to reduce thermo-elastic mistakes such as temperature control of load-bearing structural areas of the machine tools with moving cooling fluids, climate-controlling standards for whole production areas as well as continuous operation thermal stabilising hydraulic circuit also in idle process windows are already successfully practised. These measures and practices, however, increase the use of energy and reduce economic efficiency. The approach within the frame of the SFB/TR 96 follows oriented standards, that non-stationary thermal circumstance of compliance of the machining accuracy with increased productivity is safely secured, without additionally needing energy for the temperature control process. This means that the goals of the SFB/TR 96 are the solution to the conflicts of energy usage, precision and productivity with chipping production.
In phase one, a strong focus was on partial projects of fundamental modelling a parameterisation analysis. The analysis was focused on components and assemblies and was flanked by work, among other things for the validation of the models, at corresponding test benches for measurement methods and measured values. All working elements were isolated in phase one, partial models of components and assemblies, as well as measurement and modelling methods, were successfully developed and initial solutions were applied to real-life machine environments.
In phase two, the following directions in research are to be expanded into:
- Increasing complexity of the to be analysed object
- Consideration of further and complicated marginal constraints
- Taking into account more influencing factors, (i.e. cooling lubricants, moved joints) as well as
- Implementation in real-life processes
The third phase focuses on demonstrating compiled solutions implemented in real life.Open Homepage
A particular strength of the Fraunhofer-Institute for Electronic Nano Systems ENAS are the development of smart systems, so-called intelligent systems, for different purposes. These systems connect electronic components, micro and nano sensors and factors with interfaces for communication. Fraunhofer ENAS develops single components for technology used for assembly but also for system concepts and system integration technology and transferred them to their practical usage. Which means that the Fraunhofer ENAS supports client projects from the initial idea to its development, technological development or implementation with existing technology to the tested prototype. If standard components are not up to the requiremnts or they reach their limits, the Fraunhofer ENAS will then try to find a client's specific solution.
The product range and service offering of the Fraunhofer ENAS range from high precision sensors for industry, senor and actuator systems with control and electronic evaluation, to printed functionalities such as antennas or batteries to material and reliability research for microelectronics and microsystem electronics. Its primary focus lies on the development, the design and the testing of silicon-based and polymer-based MEMS and NEMS, methods and technology for the encapsulation and integration of electronic as well as metallization and interconnect systems for micro and nanoelectronics and 3D integrations. Special attention is provided to the safety and reliability of the components and systems. The fields of application are semiconductor industry, the aerospace industry, automotive industry, security sector, logistics medicine and process technology as well as mechanical engineering.Open Homepage [de]
