Sensor systems for Industry 4.0

25.03.2015

Bending, drawing, rolling, pressing – there are many ways of shaping sheet metal. But all methods have one thing in common: enormous forces and fluctuating temperatures often result in flaws in the sheets. To prevent this and to boost the efficiency of the process, sensor systems are being developed at the Fraunhofer IST which measure forces and temperatures during the forming process.

In optimizing production processes it is very important to generate measurement data at locations where measuring systems can only be integrated with difficulty, such as, for example, in direct contact between workpiece and tool.

The Fraunhofer IST is developing thin film sensors with which manufacturing can be monitored in the main stress zones, directly on the tools. The new sensorized coating systems are multi­sensoric – in other words, they contain not only piezoresistive but also thermoresistive sensor structures embedded in the wear-protection layers.

It is thus possible for the first time to measure stresses and temperatures simultaneously and with spatial resolution. With these measurement results production processes can be optimized so that, for example, cracks and creasing during the deep-drawing of sheet metal can be minimized or plastic injection-molding processes can even be improved with respect to cycle times.

It is precisely in the age of Industry 4.0 that this further development of integrated sensor technology is gaining enormously in importance. The dominant topic in the production landscape of Europe, especially in Germany, is a qualitative, quantitative, flexible and at the same time resource-efficient production.

The basis for this development is a very good understanding of the production processes on the basis of human experience and measurement results. “This is where we start with our thin-film sensors in supplying the important data needed for simulations”, says Dr. Saskia Biehl, head of the “Micro and sensor technology” group at the Fraunhofer IST.

At the Fraunhofer Adaptronics Alliance joint booth (C22) in Hall 2 the Fraunhofer IST presents the new multisensoric coating systems.

About the project
The results we have described were obtained within the SensoFut project (Sensorized Future – Sensing of temperature and pressure in harsh environments), on which the Fraunhofer IST worked together with the Fraunhofer Institute for Machine Tools and Forming Technology IWU and Sirris, the Belgian research association. SensoFut is funded in the 13th Cornet Call (Collective Research Networking) by the Federal Ministry of Economics and Technology (BMWI) and the German Federation of Industrial Research Associations (AiF) and runs until June 30, 2015.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
