Cutting high-thickness metal sheets is a basic manufacturing process common to a wide range of industrial sectors, from heavy carpentry to ship-building. Laser-cutting technology ought, in theory, to have significant advantages over traditional cutting processes, among them high cutting speed, no tool wear and a reduction in the transfer of energy to the piece of metal being cut. Yet despite the fact that commercial laser-cutting systems have been on the market for a decade, their use has not become widespread.
The problem lies in the extreme sensitivity of the process to external disturbances and in the difficulties in controlling and tuning the variables of the laser-cutting process. These make it difficult to predict and model the cutting trajectory that the laser beam should follow. Even very slight changes in the metal’s chemical composition can halt the cutting process, bringing production to a standstill. Consequently the process has to be constantly monitored and adjusted by human operators.
The three partners of project E! 1784 EUROLASER PUBLICS have devised a commercial solution in the form of a fully automated, high power laser-cutting robot which is capable of continuously cutting metals up to 20mm thick in 2D and 3D. A key innovation in the process is to simulate the cut first, to guarantee accuracy. The system enables manufacturers to dispense with human supervision as sensors automatically recognise and correct any anomalies in the cutting process.

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.
Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.
After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.
"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
