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.

The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
