In many industrial sectors, material defects in the final product can lead to premature failure and impair their safe use. Intelligent, nondestructive sensor systems play a key role in quality assurance: without damaging the material itself or changing the surface, components or parts can be inspected quickly and cost-effectively during the production process. From 23 to 26 October 2018, experts from Fraunhofer IZFP will present a robot-assisted sensor system providing quality monitoring as integral element of production processes at EuroBLECH in Hanover (hall 11, booth A25).
When time-consuming destructive testing methods are used, the damage or destruction of the products results in enormous costs of the quality inspection. Moreover, due to the fact of inspections being limited to random samples process flaws are often not detected until a considerable amount of rejects has already occurred. Thus, nondestructive testing methods provide an alternative and, after appropriate implementation, a long-term replacement for destructive methods.
Cognitive sensors for quality assurance in production
At this year's EuroBLECH, our engineers will demonstrate a robot-assisted sensor system for fast and plain integration into production processes. The automated use of intelligent, nondestructive sensor systems is not only crucial for ensuring optimum product quality in production, but also indispensable for implementing current “machine learning“ concepts.
The potential application of such systems is demonstrated by means of the robot-assisted inspection of press-hardened components using EMAT and 3MA in which EMAT enables the couplant-free defect inspection in sheet metal, while 3MA allows quantitative material characterization in parallel.
Inspection in seconds
The benefits of the robot-based combination of 3MA* and EMAT** sensors comprise the contact-free inspection, detection and assessment of multiple relevant quality characteristics of sheets in a matter of seconds.
Using this sensor-based inspection procedure, mechanical properties of steel such as residual stress states and hardness are identified and defects such as cracks or constrictions are detected at an early state. As a result, resources are spared and costs are reduced while at same time the competitiveness of producers is strengthened. The institute aggregates decades of experience and know-how in the field of combining and automating nondestructive inspection methods for production.
Cognitive sensor systems – efficient processes
Fraunhofer IZFP’s scientists and engineers develop cognitive sensor systems, i. e. intelligent, auto-adjustable sensor/actuator networks that are able to monitor, control and optimize both, single processes and entire value-added chains. In doing so, not only production processes are focused, but likewise processes in the fields of material and product development, maintenance, upkeep and recycling of raw materials. To this, the institute deploys the entire scope of available physical measuring principles.

Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
Just in time for Christmas, a Mars-analogue mission in Morocco, coordinated by the Robotics Innovation Center of the German Research Center for Artificial Intelligence (DFKI) as part of the SRC project FACILITATORS, has been successfully completed. SRC, the Strategic Research Cluster on Space Robotics Technologies, is a program of the European Union to support research and development in space technologies. From mid-November to mid-December 2018, a team of more than 30 scientists from 11 countries tested technologies for future exploration of Mars and Moon in the desert of the Maghreb state.
Close to the border with Algeria, the Erfoud region in Morocco – known to tourists for its impressive sand dunes – offered ideal conditions for the four-week...

A team of experimentalists at the U.S. Department of Energy's Ames Laboratory and theoreticians at University of Alabama Birmingham discovered a remarkably long-lived new state of matter in an iron pnictide superconductor, which reveals a laser-induced formation of collective behaviors that compete with superconductivity.
"Superconductivity is a strange state of matter, in which the pairing of electrons makes them move faster," said Jigang Wang, Ames Laboratory physicist and...
