What is laser cutting?

Laser cutting is a way to reduce precise patterns in metal, plastic, wood and virtually all other materials that one works with. It allows the level of accuracy and complexity impossible for conventional machining tools. Laser cutting works with an exciting gaseous medium, commonly carbon dioxide, causing its light reinforcement to reflect several times in the laser chamber. The light emerges from the aperture and is focused on a specific point. This is enough to melt the most common materials. Because lasers focus less and lose energy when they penetrate the material, there is a limit of about 20 mm for the depth of cut. Laser cutting machines are integrated into a larger CAD/CAM system (computer -supported computer, computer -supported rash) that takes a design file and implements it on the workpiece. These machines represent a springboard in a continuing trend from practical production, with human workers to remove more and creative design roles.

Because the laser is made up of photons, parts of its energy can bounce according to materials such as aluminum and copper alloys. These materials are also thermal conductors, which means that they distribute more even incoming heat throughout their volume. For this reason, carbon alloy and stainless steel are popular workpiece materials for laser cutting. They are poor in heat absorption, so the heat is concentrated in the laser track more easily.

Typical laser cutters allow a small size of 1 mm. Specialized lasers often have sizes that are even smaller, allowing the production of real micromachinry. The first laser cuts were carried out in 1967, as part of the spin -OFF military research project focused on lasers. Because the beams use "class 4" lasers in cutting, the machines are designed to ensure that people are never exposed to them directly. All cutting is done insidemachinery.
