2. Foldforming - Wikipedia

   en.wikipedia.org/wiki/Foldforming

   The difficulty with this is that paper and sheet metal are materials with very different properties, so artist are still limited to the materials' limits of malleability. [5] Paper material is able to bend more freely but incapable of sustaining a folded form as easily as sheet metal, and sheet metal is a thicker and tougher material to work with.

3. Hemming and seaming - Wikipedia

   en.wikipedia.org/wiki/Hemming_and_seaming

   Hemming and seaming are two similar metalworking processes in which a sheet metal edge is rolled over onto itself. Hemming is the process in which the edge is rolled flush to itself, while a seam joins the edges of two materials. [1] Hems are commonly used to reinforce an edge, hide burrs and rough edges, and improve appearance. [1]

4. Bending (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Bending_(metalworking)

   Though faster than folding, wiping has a higher risk of producing scratches or otherwise damaging the sheet, because the tool is moving over the sheet surface. The risk increases if sharp angles are being produced. [2] This method will typically bottom or coin the material to set the edge to help overcome springback.

5. Types of press tools - Wikipedia

   en.wikipedia.org/wiki/Types_of_press_tools

   Press tools are commonly used in hydraulic, pneumatic, and mechanical presses to produce the sheet metal components in large volumes. Generally press tools are categorized by the types of operation performed using the tool, such as blanking, piercing , bending , forming , forging , trimming etc.

6. Sheet metal - Wikipedia

   en.wikipedia.org/wiki/Sheet_metal

   Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its ...

7. Brake (sheet metal bending) - Wikipedia

   en.wikipedia.org/wiki/Brake_(sheet_metal_bending)

   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. It is also known as a bending machine or bending brake or in Britain as a sheet metal folder or just a folder.
