Rolling cone motion is the rolling motion generated by a cone rolling over another cone. In rolling cone motion, at least one of the cones is convex , while the other cone may be either convex, or concave, or a flat surface (a flat surface can be regarded as a special case of a cone whose apex angle equals π {\displaystyle \pi } ).
For thin sheet metal with a thickness less than 200 μm (0.0079 in), [citation needed] the rolling is done in a cluster mill because the small thickness requires a small diameter rolls. [10] To reduce the need for small rolls pack rolling is used, which rolls multiple sheets together to increase the effective starting thickness.
A roller-cone bit is a drill bit used for drilling through rock that features 2 or 3 abrasive, spinning cones that break up rock and sediment as they grind against it. Roller-cone bits are typically used when drilling for oil and gas. [1] A water jet flowing through the bit washes out the rock in a slurry. [2]
A tandem rolling mill is a rolling mill used to produce wire and sheet metal. It is composed of two or more close-coupled [clarification needed] stands, and uses tension between the stands as well as compressive force from work rolls [clarification needed] to reduce the thickness of steel. It was first patented by Richard Ford in 1766 in England.
Fig. 1. A shear formed product: a hollow cone with a thin wall thickness. Shear forming, also referred as shear spinning, is similar to metal spinning. In shear spinning the area of the final piece is approximately equal to that of the flat sheet metal blank. The wall thickness is maintained by controlling the gap between the roller and the ...

Roll forming, also spelled roll-forming or rollforming, is a type of rolling involving the continuous bending of a long strip of sheet metal (typically coiled steel) into a desired cross-section. The strip passes through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired ...
