Researchers at Purdue University are working with industry to develop an "intelligent" system that could save U.S. companies $1 billion annually in manufacturing costs by improving precision-grinding processes for parts production.

Commonly referred to as CNC machines, the grinders cost up to $1 million and are widely used in industry to manufacture parts. Shin is leading research work that uses artificial intelligence software to improve the precision of such CNC grinding machines, which potentially could yield annual savings of $1 billion for U.S. companies.

"Precision grinding is currently an art that relies heavily on the experience and knowledge of employees who have been in the business for years," said Yung Shin, a professor of mechanical engineering who is leading the Purdue portion of the research. "The problem is that many factories don’t have enough of these very experienced people, so a lot of grinding processes are run under suboptimal conditions.
"Our system strives to enable relatively inexperienced employees to operate grinding machinery with the same precision as these rare, highly experienced workers."

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
