Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
New Manufacturing Technologies for New Products
Implementing innovative concepts, such as for more efficient engines, mostly accompanies with advances in manufacturing technologies. Production tolerances of modern plants thus suffice to process metal components in the micrometer range and are just a thousandth of a millimeter thick. At the same time, a plant must be highly flexible so it can compensate for any fluctuations in raw materials and manufacture a wide range of products. That is why production technology’s next aim is to have plants that can manufacture individual components with the precision and at the cost of mass production.
Laser Measurement Technology as a Key Component
Sensors that can work precisely and reliably even under unfavorable conditions are paramount to monitoring and regulating such manufacturing processes. Interferometers are used under laboratory conditions to measure the shape of components with the highest precision – for example, thickness of sheet metal, roundness of rollers, and eccentricity of waves. In fact, Interferometers are so precise that they can be used to determine not just the component’s shape but also its surface roughness.
Sensors with Digitized Expert Knowledge
To this end, an interferometer’s settings must be adapted precisely to the measurement task at hand. This especially requires correct exposure time and focus; similar to taking a photo. In April this year, the collaborative project INSPIRE was started with the aim of developing an interferometer that can adapt to varying measuring conditions. “The sensors will have digitized expert knowledge and can autonomously optimize the settings,” explains Dr. Hölters from Fraunhofer ILT in Aachen. He coordinates the INSPIRE project, in which four other small and medium-sized enterprises are participating. With the development of fast control electronics, the sensors can adapt to rapidly changing measuring conditions within microseconds. This development will benefit conventional processes such as the cold rolling of sheet metal as well as machining processes such as welding.
Collaborative Project INSPIRE
The project idea of “Interferometric Distance Sensors with Automated Subsystems for Precision Inline Measurement to Regulate Automated Manufacturing Processes,” which in German produces the acronym INSPIRE, convinced the German Federal Ministry of Education and Research (BMBF) to pledge half the funding for the three-year long collaborative project as part of the “Digital Optics” funding initiative. Companies participating in the INSPIRE project are LSA – Laser Analytical Systems & Automation GmbH and Beratron GmbH from Aachen, HIGHYAG Lasertechnologie GmbH from Kleinmachnow, and Friedrich Vollmer Feinmessgerätebau GmbH from Hagen.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
