Deep drawing, a sheet metal forming process designed to produce hollow shells, was developed in the mid-19th century. Since that time, much has been published regarding deep drawing dies and processes, but very little can be found regarding its origin.
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. However, studies have shown that it can be applied to polymer and composite sheets too. Generally, the sheet is formed by a round tipped tool, typically 5 to 20mm in diameter.is a metal forming process in which a force is applied to a piece of sheet metal, causing it to bend at an angle and form the desired shape. In bending process, the outside portion of the sheet is in. Search the history of over 866 billion web pages on the Internet. Search the Wayback Machine An illustration of a magnifying glass. .
