Computer Controlled Cutting

What Is Laser Cutting?:

Laser stands for Light Amplification by Stimulated Emission of Radiation. The laser is used to cut materials such as acrylic and wood. It is usually used for Industrial manufacturing. Over the years, laser cutting has been used by many organisations including schools, small businesses and even people with hobbies. When the machine points the laser at the intended material, it would result in it being burned, melted, or vaporized away. Optics are present on the machine to help focus the laser as well as CNC for motion control.

Laserable Materials:

  • Cardboard
  • Wood
  • Acrylic
  • Delrin
  • Fabric
  • Ceramic
  • Glass

    • Prohibited Materials:

  • PVC
  • Plastic Leather
  • Moleskin
  • Polycarbonate/Lexan
  • HDPE
  • Polystyrene Foam
  • Fiberglass
  • Carbon Fiber
  • Butane/Gas

    • *Flame test: If it flames, it should not be cut*

    Laser Settings:

  • Power:

    • - Higher Burns deeper

    - Too much or too little sacrifices detail

  • Speed:

    • - Higher saves time, burns shallower

    - Too high or low speeds reduces detail

  • Frequency (PPI):

    - # pulses per inch of travel

    • - Higher increase burning/melting effect

    - Acrylic: 500 ~ 1000

    - Wood: 100 ~ 500

  • Rule of Thumb:

    • - Doubling power doubles depth of cut

    - Halving speed doubles depth of cut

  • Use vendor recommended settings as a starting point
