In this type of manufacturing, the technology is computer-generated, and it means that the output of a powerful laser is being directed towards the material that needs to be cut. The result is the transformation of the material according to its composition (i.e. it can burn, melt or vaporize away) and a surface finish of high quality. Industrial laser cutting is mainly concerned with cutting piping and structural materials, as well as flat-sheet material.
The advantages that laser cutting holds over the traditional mechanical cutting are numerous. For instance, the lack of any physical contact is probably the most important advantage, or at least as important as precision, given by the fact that there is no wear on the laser. Furthermore, the heat affected zone that lasers have is significantly smaller, which means that the chances of warping the material are also reduced.
A similar process to laser cutting is laser etch; the most notable difference between the two procedures is that, in the latter, the material is not fully cut through by the laser. As the name describes it, laser etch refers to objects being etchd or marked using a laser.
Some materials have been specially designed to be used in laser cutting, laser etch, or similar procedures, in which the use of laser is involved. Such materials include novel metal alloys or polymers, and given their “laserable” nature, the effect of laser etch was all the more notable.
