2. Sheet metal - Wikipedia

   en.wikipedia.org/wiki/Sheet_metal

   Sheet metal can be cut in various ways, from hand tools called tin snips up to very large powered shears. With the advances in technology, sheet metal cutting has turned to computers for precise cutting. Many sheet metal cutting operations are based on computer numerically controlled (CNC) laser cutting or multi-tool CNC punch press.

3. Plasma cutting - Wikipedia

   en.wikipedia.org/wiki/Plasma_cutting

   Plasma cutting grew out of plasma welding in the 1960s, and emerged as a very productive way to cut sheet metal and plate in the 1980s. [1] It had the advantages over traditional "metal against metal" cutting of producing no metal chips, giving accurate cuts, and producing a cleaner edge than oxy-fuel cutting.

4. Metalworking - Wikipedia

   en.wikipedia.org/wiki/Metalworking

   Metalworking generally is divided into three categories: forming, cutting, and joining. Most metal cutting is done by high speed steel tools or carbide tools. Each of these categories contains various processes. Prior to most operations, the metal must be marked out and/or measured, depending on the desired finished product.

5. Bending (metalworking) - Wikipedia

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

   Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. Commonly used equipment include box and pan brakes , brake presses , and other specialized machine presses .

6. Metal fabrication - Wikipedia

   en.wikipedia.org/wiki/Metal_fabrication

   Cutting torches can cut large sections of steel with little effort. Burn tables are CNC (computer-operated) cutting torches, usually powered by natural gas. Plasma and laser cutting tables, and water jet cutters, are also common. Plate steel is loaded on the table and the parts are cut out as programmed.

7. Laser cutting - Wikipedia

   en.wikipedia.org/wiki/Laser_cutting

   When cutting low carbon steel with laser power of 800 W, standard roughness Rz is 10 μm for sheet thickness of 1 mm, 20 μm for 3 mm, and 25 μm for 6 mm. R z = 12.528 ⋅ S 0.542 P 0.528 ⋅ V 0.322 {\displaystyle Rz={\frac {12.528\cdot S^{0.542}}{P^{0.528}\cdot V^{0.322}}}}
