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.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
