Forming processes tend to be categorised by differences in effective stresses. These categories and descriptions are highly simplified, since the stresses operating at a local level in any given process are very complex and may involve many varieties of stresses operating simultaneously, or it may involve stresses which change over the course of the operation.
Precision Metalforming Association or PMA is a trade association [1] representing the $137-billion metalforming industry of North America: the industry that creates precision metal products using stamping, fabricating, spinning, slide forming and roll forming technologies, and other value-added processes.
Incremental sheet forming (or ISF, also known as Single Point Forming) is a sheet metal forming technique where a sheet is formed into the final workpiece by a series of small incremental deformations.
A fireman turning a bar of metal on a lathe on the USS Harry S. Truman in 2004. Metalworking is the process of shaping and reshaping metals in order to create useful objects, parts, assemblies, and large scale structures.
Commercial Metals Company (CMC), headquartered in Irving, Texas, is a producer of rebar and related products for the construction industry. Along with Nucor, it is one of two primary suppliers of steel used to reinforce concrete in buildings, bridges, roads, and infrastructure in the U.S.
Foldforming [1] is a technique of metalworking whereby metal is folded, repeatedly forged and annealed, and unfolded; at which stage it generally has a dramatic new three-dimensional form.
Manually driven bending brake Cornice brake Hydraulic press - 400T. A brake is a metalworking machine that allows the bending of sheet metal.A cornice brake only allows for simple bends and creases, while a box-and-pan brake also allows one to form box and pan shapes.
Animation of a power press with a fixed barrier guard. Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape.
