Sheet and strip metal, including steel, aluminum, copper and brass, goes into cars, aircraft, ships, appliances, beverage cans, medical instruments and countless other products. It is produced in rolling mills, which squeeze metal between rollers to thin it.

What they work on
- Develop a physics-based model that predicts which process conditions lead to 3rd octave chatter vibration during cold rolling of flat metals on multi-stand tandem mills.
- Identify which rolling parameter interactions reinforce or eliminate 3rd octave chatter, to guide new chatter-mitigation techniques and better rolling schedule set-ups.
- Use model insights, developed with metal producers and machine builders, to inform rolling mill designs that allow higher rolling speeds before chatter begins.
More about the research
In cold rolling mills, a vibration the industry calls "3rd octave chatter" sets a speed limit. Above a threshold speed, the mill shakes, which limits production and can cause severe damage. Because the physics is complex, these threshold speeds are hard to predict when designing mills or trying new alloys and rolling schedules. Much US rolling-mill design expertise has also been lost as production moved overseas.
Why it matters
Predicting and preventing chatter could let cold rolling mills run faster without damage, raising productivity for US producers of steel, aluminum and other flat metals. This could lower raw material costs for industries that rely on sheet metal, such as automotive, aerospace, packaging and appliances. It could also help mill designers and operators set up new alloys and rolling schedules with less trial and error.
