How Laser Cutting Works

Lasers are known to serve a lot of purposes in our industry. One of its several uses is to efficiently and effectively cut through metallic materials. When it comes to laser cutting aluminums and mild steel materials, the cut is definitely precise, smooth, and allows cutting even the most sophisticated holes and shapes.

A lot of individuals are already knowledgeable that “LASER” means light amplification by stimulated emission of radiation. But, do you know how lasers effectively cut materials?

Laser cutting works through operating an extremely powerful laser beams, in a very accurate focus length, to any object which they intend to engrave or cut. Laser cutter machines or equipment are utilized in laser cutting. Laser cutters effectively cut objects just like what other computer operated tools, but laser beams are utilized in this machine rather than blades.

There are basically three primary kinds of lasers utilized in the laser cutting process. One of them is the CO2 laser and this kind of laser is best for doing cuts, bore, and engraves. Next is the neodymium or shortened as Nd, which is utilized for boring and needs great level of energy but lesser repetition. Another kind of laser is the neodymium yttrium aluminum garnet, shortened as Nd-YAG, is a laser that is somewhat similar to Nd, but requires extreme power for engraving and boring.

Laser cutting also has several procedures in cutting different kinds of objects and below are some of the common procedures used.



  • Thermal stress cracking – fragile objects are certainly sensitive when it comes to this particular method. Beams are emphasized on the object producing local heats and thermal extension. This would then lead to cracking which could be controlled through the beams. This method is generally utilized to cut glasses.
  • Vaporization – in this method, the emphasized beams will heat up the object’s surface until it reaches the boiling level and creates a keyhole. Keyholes would then start rapid raising of its absorption quality and expanding the depth of the hole. While the hole starts to become deeper and the object reaches its boiling point, vaporization is then produced, eroding the melted walls blasting wastes out and quickly deepening the hole. Objects that do not melt like woods and other materials are generally using this kind of laser cutting procedure.
  • Melting and blowing – sometimes called as fusion cutting, this method utilizes extreme pressured gas to blast on melted objects from the cutting space, significantly lessening the power necessity. Initially, the object is introduced to heat until it melts, then gas jet blasts the melted object out from the cut preventing the necessity to increase the object’s temperature a lot more. Objects which generally utilize this method are metallic.

Laser cutting is actually being used widely in the industry nowadays from the fact that it literally serve several purposes, especially in the manufacturing businesses. In addition, materials that were laser cut have very smooth edges and precise designs. This basically indicates that laser cutting is definitely an effective and great method for cutting materials.
