One of High-Tech Methods for Cutting Materials Is with Laser Cutting Machines.

One of the most popular high-tech methods for cutting materials from metal to fabrics today is with laser cutting machines. The reasons are simple and that is that laser cutting machines offer several advantages in the form of precision and flexibility, as well as the fact that Laser Cutting is very clean in that it doesn't generate any dust. How Laser Cutting Machines Cut In short, laser cutting is done by focusing a beam of high intensity energy on the Material to be cut, which causes it to either melt, burn or vaporise, depending on the type of material being cut and the intensity of the laser beam. Focusing More Than One Laser Beam Laser resonators are used to focus more then one laser beam on a single area, resulting in a faster more intensive cut. Or for softer more easily cut materials, such as plastics or fabrics, only a single laser beam would be used to make a laser cut. The Use Of Gas With Laser Cutting Machines Gases are also used with laser cutting machines to effect the cutting process. For instance, just as with standard arc welding, inert gas such as nitrogen can be introduced into the cutting zone to prevent any chemical reactions from occurring as a result of the heat and energy being produced by the laser cutting process. The Use Of Oxygen With Laser Cutting Machines Also, just as with standard gas welding oxygen can be introduced into the zone that is being effected by the laser cutting machine to create more heat. This would be done on materials such as metals that would tend to melt from the added heat. Todays Laser Cutting Machines Laser cutting machines and technologies have allowed todays manufactures to increase productivity and cut and create with far more precision. Also, surfaces of odd shapes that in the past would have been very difficult to cut with standard cutting devices are now easily cut with laser cutting machines. Source: hicow.com
