Researchers at Purdue University have found a way to fix a long-standing issue in manufacturing, where cutting a piece of metal can make its edges splinter or break apart.

They hope their solution will reap big savings in fuel and production costs.

The problem is called a shear-band. It's a deformity that occurs when a cutting machine pushes through metal, scrunching up its edges at a microscopic level.

Today's manufacturers are using lighter materials -- and less of them -- to make products cheaper and more efficient. That's transforming many Indiana manufacturing jobs.

Now, the Indiana Manufacturers Association, or IMA, is teaming up with a federal group to train more workers in what's known as lightweighting.
