During the EuroMold 2011 tool and die making trade fair, the Fraunhofer IPT will be presenting this robot-based processing plant at the joint Fraunhofer booth C66 in Hall 11.

Transferring manual dexterity to a robot
The Fraunhofer IPT’s automated plant uses a lineal grinding motion to remove the milling traces that arises when manufacturing forming tools and molds. The manufacturing unit on display at the trade fair consists of a conventional industrial robot and a pneumatic smoothing tool in which the processing movements and the forces acting on the workpiece are introduced and controlled via air pressure. The processing path is programmed using the so-called "CAx-Framework" software especially developed by the Fraunhofer IPT.
Without the right tool holder or process parameters for the robot to reproduce the manual dexterity and the experience of a human operator, it was virtually impossible to automate the smoothing and brush polishing processes on freeform mold surfaces. As part of the "Green Carbody Technologies Innovation Alliance" (InnoCaT), the engineers in Aachen therefore performed scientific investigations to find the right processing methods and tools for different materials and geometries. A comparison of the results of an optical component measurement with the original design data then provided the basis for developing the optimum processing strategy for automated finishing operations.
The plan is to continue developing the system in order to fully automate the processing of free form tools both with robots as well as in milling machines.
The "Green Carbody Technologies Innovation Alliance" is an association of over 60 companies and scientific institutes that aims to make automotive manufacturing more energy and resource efficient. As part of this alliance, the Fraunhofer IPT develops new tool and mold manufacturing systems together with its industrial partners in order to reduce the resource consumption and manufacturing costs involved in component production.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
