This Demonstration on the manufacturing process of flat rolling shows how roll radius, friction, and plate thickness determine the maximum change in plate thickness that can be achieved in a single pass through the rollers (maximum draft). It also calculates the force that has to be exerted by the rollers on the metal plate to achieve this draft. The kip is a non-SI unit of force equivalent to 1000 pounds-force.
