Quantity and Quality: Novel Sensor Module Ensures Efficient Production

12.03.2013
Flexibility, individuality and efficiency are some of the most powerful driving forces in industrial production.

Defects, especially fractures and wrinkles, slow down production processes and increase the reject rate when forming mass products, e. g. during deep-drawing of automotive parts or the manufacture of prototypes.

Fraunhofer researchers have developed a multifunctional thin film system which is located directly in the main load zones and allows for a sensitive and highly dynamic monitoring of the process. A variety of sensor modules will be presented from April 8 – 12, 2013 at Hannover Messe (hall 3, booth D25 and hall 2, booth D18).

There is almost no room for extras where stress in forming processes is at its highest level. Here, precision is the keyword. Therefore sensor systems that monitor the process are often located far from the critical range of forming tools. Researchers of the Fraunhofer Institute for Surface Engineering and Thin Films develop multifunctional sensor modules that are customized for the respective system and incorporated in the main load zones free of play, thus making a long-term stable acquisition of relevant process parameters possible.

The main part of the thin film sensor system is the DiaForce® layer – an amorphous hydrocarbon coating developed at Fraunhofer IST. The layer combines tribological stability with piezoresistive properties so that the sensor can measure forces directly in the main load zones without suffering from wear. Online monitoring, for example of the draw-in movement of sheet metal during deep-drawing processes, and accurate information acquisition from direct contact with the sheet become possible with the DiaForce® layer.
The sensor module can be applied in a variety of fields: Not only deep-drawing systems but also die-cutting systems are important application areas. Here, the module measures the cutting forces in direct contact with the punch. The thin film sensor system offers maximum flexibility when it is incorporated in washers and, in this form, can be built into virtually any system geometry without much effort, ensuring long-term stable data acquisition and monitoring of the production process.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
