When machining, most people focus on the part or product they are producing. Purdue professor Srinivasan Chandrasekar and his colleague, Dale Compton, however, find the scrap most interesting. While studying machining processes, the researchers found that the metal chips produced were composed of nano-crystalline structures, which possessed characteristics such as high strength and wear resistance. "After that, we lost all interest in the more complicated processes and concentrated on the residue," Chandrasekar laughs. Typically the chips are collected as scrap, melted down and reused. But melting turns these natural nanocrystals back into ordinary bulk metals, removing their super strength and other unusual properties. "We've known that if a material is deformed beyond recognition, one can create a new stronger material with different characteristics," Chandrasekar continues. The shaving tool applies the correct amount of pressure to deform the metal shaving. He believes that a machining process could be designed to create materials with specific crystal sizes, which could have a number of applications. For example, the shavings could be made into powder and added to other materials to form a new class of composites. Or the powder could be compressed into solid bodies and used to build fuel system components, turbocharger blades, bearings, or gears with better wear resistance than those used today. Nanocrystal materials have long been a pie-in-sky material because they cost about $100 per pound to produce. Chandrasekar expects that, with the new patent pending process, will cost only $1 per pound above the cost of the raw material.

On Memorial Day, Americans remember the sacrifices the US armed forces have made, and continue to make, in service to the country. All of us should also consider the developments in technological capabilities and equipment over the years that contribute to the success of our military operations.
In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
Advanced visualization can depict an entire plant in motion, while also detailing an individual workstation. Individual products can be rendered different for each discipline involved — marketing, engineering, or suppliers.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
