Laser cutting is an expertise that uses a laser to cut materials, and is normally used for industrial manufacturing applications, but is also planning to be used by small businesses and schools. A typical commercial laser for cutting materials would involve a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. Industrial laser cutters are used to cut flat-sheet material as well as structural and piping materials. Laser cutting is mainly done in custom plastic parts, but it can also applicable in custom wood, foam parts and rubber as well as thin custom metal parts.


Advantages of laser cutting over mechanical cutting comprise easier work holding and reduced infectivity of work piece. Accuracy is also better, since the laser beam does not wear throughout the process. There is also a cheap chance of warping the material that is to be cut, as laser systems have a little heat-affected zone. Some materials are also very hard or unfeasible to cut by more conventional ways.

Types of Laser Cutting:

There are three types of lasers used in laser cutting: CO2 Laser Cutting; Neodymium (Nd) Laser Cutting; Neodymium yttrium-aluminum-garnet (Nd-YAG) Laser Cutting.

The CO2 laser is suited for cutting, boring, and engraving. CO2 lasers are used for industrial cutting of many materials including aluminum, mild steel, wax, stainless steel, titanium, paper, plastics, fabrics and wood.

The neodymium (Nd) and neodymium yttrium-aluminum-garnet (Nd-YAG) lasers are equal in style and vary only in function. Nd is applicable for boring and where high energy but low repetition is necessary. The Nd-YAG laser is applicable for boring and engraving and where very high power is required.

Methods Available in Laser Cutting:

Some methods available for laser cutting are briefly discussed below:

  1. Vaporization cutting: Non melting material such as wood, carbon and thermo set plastics are usually cut by this method.
  2. Melt and blow or fusion cutting: It uses high-pressure gas to blow molten material from the application area, significantly decreasing the power requirement. Materials cut with this process are generally metals.
  3. Thermal stress cracking: This method is usually used in cutting of glass as brittle materials are mostly sensitive to thermal fracture.
  4. Reactive cutting or flame cutting: Mostly used for cutting carbon steel which thicknesses is over 1 mm. This process can be used to cut very thick steel plates with relatively little laser power.
