Ohio State's Glenn Daehn uses magnetic pulses to
"bump" metal into shape
A process developed at Ohio State University for shaping metal parts
using magnetism has reached a new milestone -- one that may cut manufacturing
costs and help preserve the environment.
The process could also expand manufacturers’ choice of available
metals, and enable the use of aluminum parts in lighter, fuel-efficient
automobiles.
Glenn S. Daehn, professor of materials science and engineering, and
his colleagues pioneered hybrid electromagnetic metal forming in 1999,
while collaborating with the “Big Three” automakers. With
this process, a traditional tool and die stamps the general shape of
a part out of sheet metal. Afterward, a magnetic field pushes at specific
locations of the sheet metal to form fine details or complex shapes...
