sheetmetal

A novel way to create sheet metal could generate big energy savings in motorized machines.

Purdue University engineers are getting a $1.5 million federal grant to begin studying the new process and its applications this summer.

The three-year project will focus on adding larger amounts of silicon to the small steel parts that help power electric motors.

Silicon helps the steel waste less electricity, says Purdue materials engineer Kevin Trumble, but adding enough to make a difference isn’t easy.

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.
