Conference on Laser Polishing – LaP: Fine Tuning for Surfaces

12.07.2018

It’s all about the finishing touches, in the truest sense of the word, for the third time at the Fraunhofer Institute for Laser Technology ILT in Aachen on the 12th and 13th of September 2018. After the first two successful conferences on laser polishing, the institute expects more than 70 participants from industry and research to attend the third “Conference on Laser Polishing – LaP”.

Laser polishing is a relatively new process that has only been used for selected fields of applications in the industry: for example, machining metals for toolmaking and automotive engineering, as well as processing glass optics.

International conference

Prior to 2014, the pioneers of this process did not have the opportunity to exchange research results in a wider and international context. That is why Fraunhofer ILT launched the first “Conference on Laser Polishing – LaP” in 2014, which has been held every two years since then and has become the international meeting place for laser polishing experts.

“If you look at the specialist literature, more than 80% of the research groups working on the topic worldwide have attended the LaP conference so far,” states Dr. Edgar Willenborg, Head of the Laser Polishing Group at Fraunhofer ILT.

“Researchers from all over the world – from China, Russia, Canada, many European countries and the USA – have come to the conference. That's why English is the conference language, also at the third LaP”. While the majority of the 20 lectures come from academia, the participants come roughly equally from industry and research.

Focus on technical surface properties

“Researchers are concentrating more and more on the properties of surfaces relevant to specific applications,” says the expert. “In the beginning, it was primarily about lowering the roughness, but now more and more functional tests and application tests are being added”.

For example, users would like to eliminate microdefects to increase the lifetime of a metallic component, or to polish particularly complex optical glass surfaces. One of the new applications, covered for the first time at LaP, is the laser polishing of additively manufactured components made of plastic.

Many speakers have one goal in common: to create a broad, scientific basis for the industrial use of laser polishing. Willenborg: “With hand polishing, it is possible to achieve a lower roughness on metallic components, but it is much slower than laser polishing”.

With the laser, on the other hand, complex geometries can be polished automatically, reproducibly and significantly faster. While the quality of laser polishing for many applications is already sufficient, the processing speed must be increased even more. “Accelerating laser polishing is currently an important trend, as it makes the process economical for a wide range of applications,” says Willenborg.

Im Focus: Megakaryocytes act as „bouncers“ restraining cell migration in the bone marrow

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.

Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...

Im Focus: Artificial neural network resolves puzzles from condensed matter physics: Which is the perfect quantum theory?

For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.

Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...

Im Focus: Extremely hard yet metallically conductive: Bayreuth researchers develop novel material with high-tech prospects

An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".

The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...

Im Focus: Modelling leads to the optimum size for platinum fuel cell catalysts: Activity of fuel cell catalysts doubled

An interdisciplinary research team at the Technical University of Munich (TUM) has built platinum nanoparticles for catalysis in fuel cells: The new size-optimized catalysts are twice as good as the best process commercially available today.

Fuel cells may well replace batteries as the power source for electric cars. They consume hydrogen, a gas which could be produced for example using surplus...

Mushrooms: Darker fruiting bodies in cold climates

The fly agaric with its red hat is perhaps the most evocative of the diverse and variously colored mushroom species. Hitherto, the purpose of these colors was...
