2. 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. Early plasma cutters were large ...

4. Laser cutting - Wikipedia

   en.wikipedia.org/wiki/Laser_cutting

   Laser cutting for metals has the advantage over plasma cutting of being more precise [10] and using less energy when cutting sheet metal; however, most industrial lasers cannot cut through the greater metal thickness that plasma can. Newer laser machines operating at higher power (6000 watts, as contrasted with early laser cutting machines ...

5. Electrical discharge machining - Wikipedia

   en.wikipedia.org/wiki/Electrical_discharge_machining

   An electrical discharge machine. Electrical discharge machining ( EDM ), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). [1] Material is removed from the work piece by a series of rapidly recurring ...

6. Electromagnetic shielding - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_shielding

   Electromagnetic shielding. Electromagnetic shielding cages inside a disassembled mobile phone. In electrical engineering, electromagnetic shielding is the practice of reducing or redirecting the electromagnetic field (EMF) in a space with barriers made of conductive or magnetic materials. It is typically applied to enclosures, for isolating ...

7. Cutting tool (machining) - Wikipedia

   en.wikipedia.org/wiki/Cutting_tool_(machining)

   In the context of machining, a cutting toolor cutteris typically a hardened metal toolthat is used to cut, shape, and remove material from a workpieceby means of machining toolsas well as abrasive toolsby way of shear deformation. The majority of these tools are designed exclusively for metals. There are several different types of single-edge ...
