  3. Laser cutting - Wikipedia

    en.wikipedia.org/wiki/Laser_cutting

    For sheet metal cutting, the focal length is usually 1.5–3 inches (38–76 mm). [7] [8] Advantages of laser cutting over mechanical cutting include easier work holding and reduced contamination of workpiece (since there is no cutting edge which can become contaminated by the material or contaminate the material). Precision may be better since ...

  7. Electron-beam machining - Wikipedia

    en.wikipedia.org/wiki/Electron-beam_machining

    EBM can be used for very precise cutting or boring of a wide variety of metals. Surface finish is better and kerf width is narrower than those for other thermal cutting processes. EBM process is best suitable for high melting point and high thermal conductivity materials. The EBM beam is operated in pulse mode.
