At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive manufacturing to laser polishing – are now commonplace in large-scale production.
Cost structures, new materials and new processes are framing the demands placed on lasers and process engineering, of which process control is an essential element. Process control has developed steadily over the past few years in terms of performance and reliability, and is being used more and more by manufacturing companies.
More stringent demands placed on process monitoring
New sensors paired with innovative signal analysis now permit more accurate diagnosis of faults in laser-based processes. Today’s lasers offer equally high levels of performance and brilliance. This means that laser processes are becoming ever faster, which often leads manufacturers to exhaust process limits as they seek to maximize profitability.
Process windows are thus becoming narrower and narrower, which in turn raises the importance of process monitoring. The demands placed on the sensor technology in process control are thus correspondingly high: suitable measuring points need to be identified in the manufacturing process, the correct sensors need to be integrated and appropriate automated processes need to be found to ensure rapid detection of quality issues. Overall this represents a considerable challenge for users and manufacturers.
Accumulated expertise: the Industry Working Group for Process Control
At the process control seminar during AKL’16, it was apparent that there is great interest among users in new developments in process control. To meet users’ needs for support in this area, the Fraunhofer Institutes for Laser Technology ILT and for Production Technology IPT in Aachen announced the launch of the Industry Working Group for Process Control in Laser Material Processing.
The working group is aimed at users of laser techniques across a wide variety of sectors. Together with the research units, users in the working group can define and carry out pre-competitive projects such as feasibility studies or develop benchmarks, for instance. Members of the working group have access to the latest expert knowledge and trend analyses.
Particular emphasis is placed on encouraging an exchange of information, both among users themselves and with experts. Moreover, members have direct access to research and funding projects as well as training opportunities. The activities of the working group are funded by membership fees. To date, some ten companies have expressed interest and are in discussions with the organizers. Further members are very welcome!
With the inaugural meeting planned for autumn 2016, interested parties are now free to submit topics and questions for discussion.

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“.

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.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
