You are very perceptive.  In fact, vibrations have been used in many ways
to form and join metals.  Examples include using ultrasonic vibrations in
welding, using vibrating conical dies to reduce friction during extrusion
of metal parts, and using vibrations simply to transport parts along an
assembly line or to feed them into a machine.  Since high friction or
inadequate lubrication can cause marring and damage to the surfaces of
metals during forming operations, like forging, bending, and rolling, it
might be worthwhile to explore friction reduction in sheet metal forming
processes through vibrations.

The relationship between friction and vibration in metalworking has been
studied in the past, much of that work was done in the Former Soviet
Union. Currently, there is interest in friction-vibration research in the
Department of Mechnical Engineering at Carnegie Mellon University in
Pittsburgh, PA.  I suggest that you contact the department chairman there
for more information on their current work.  You might also contact ASM
International (formerly called the American Society for Metals) to see
whether additional references to vibrations in metalworking are available
