  2. Laser cutting - Wikipedia

    en.wikipedia.org/wiki/Laser_cutting

    Laser cutting for metals has the advantage over plasma cutting of being more precise [11] 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 ...

  3. Laser engraving - Wikipedia

    en.wikipedia.org/wiki/Laser_engraving

    The same conduction that works against the spot vaporisation of metal is an asset if the objective is to vaporise some other coating away from the metal. Laser engraving metal plates are manufactured with a finely polished metal, coated with an enamel paint made to be "burned off". At levels of 10 to 30 watts, excellent engravings are made as ...

    For cut path, most machines give the options of tracing the vectors, cutting outside the vectors, or cutting inside the vectors. The operator determines the center point of the part, clamps the part onto the table, moves the bit directly above the marked center and down to the face of the part, and marks this as the starting point.

  5. 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 ...

  6. Laser beam machining - Wikipedia

    en.wikipedia.org/wiki/Laser_beam_machining

    Milling with a laser is a three dimensional process that requires two lasers, but drastically cuts costs of machining parts. [2] [7] Lasers can be used to change the surface properties of a workpiece. The appliance of laser beam machining varies depending on the industry. In light manufacturing the machine is used to engrave and to drill other ...

  7. Die (manufacturing) - Wikipedia

    en.wikipedia.org/wiki/Die_(manufacturing)

    Steel-rule die, also known as cookie cutter dies, are used for cutting sheet metal and softer materials, such as plastics, wood, cork, felt, fabrics, and paperboard. The cutting surface of the die is the edge of hardened steel strips, known as steel rule. These steel rules are usually located using saw or laser-cut grooves in plywood.
