The Timken Co. is using a $1.4-million grant from the US Department of Energy to develop an online ultrasonic measurement system that increases the efficiency of manufacturing seamless steel tubing. The new manufacturing process uses a laser-ultrasonic system for providing on-line measurement of wall thickness and eccentricity of steel tubing for manufacturing control. According to the US Department of Energy, the system improves productivity of seamless mechanical steel tubing by 30 to 50% while reducing energy consumption and emission of pollutants. How? First, consider that current methods require stopping production runs for manual measurement. Machinery adjustments for each run result in a loss of approximately three of ten tubes made. "And while you stop the machinery and make adjustments three or four times, your plant sits idle," says Robert Kolarik, an engineer and project manager for the Timken Co. "The new online ultrasonic measurement method eliminates the need for stopping the machine for manual measurements. "Just like traditional ultrasound, we use sound waves. Knowing the acoustic velocity of the steel allows us to determine the wall thickness and eccentricity," he says. Scrapped tubes resulting from out-of-tolerance specifications are eliminated.

Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
Weaned on the relatively effortless connectivity of today’s massive variety of consumer electronic products, automation users in the IIoT will likely not tolerate too many competing, piecemeal standards for long. And the Industrial Internet Consortium is trying to preempt history.
