Laser cutting is a form of technology that uses an optical device to cut materials and is generally used for industrial production applications; however, it is beginning to be used by universities, small businesses, and hobbyists. The optical device cutting process works by guiding the output of a high-power optical device, by computer, onto the fabric to be cut.
The material is then melted or burned, vaporized or, in some cases, carried away by a gas jet leaving an edge with a high quality surface finish. Industrial optical devices or laser cutters are used to cut flat sheet material and also such as structural and piping materials. The use of an optical device for cutting may be a manufacturing method that could eliminate the requirement of machining in various engineering jobs, allowing manufacturers to reduce their production costs.
Optical cutting has a number of advantages over plasma cutting in that this method is much more precise and uses less energy when cutting sheet metal and steel. Also, newer laser machines, for example the new 7 Kw machine, now approach plasma machines in their ability to cut thick materials.
The levels of precision and edge quality achieved with laser cutting machines are higher than more traditional cutting strategies, as the laser beam is not worn during the laser cutting method. Optical device cutting technology also allows manufacturers to cut and design advanced shapes without the need for tools and at speeds identical to or faster than alternative cutting strategies.
The fact that laser cutting technology can offer fabricators greatly reduced contamination of the work piece has a number of advantages over more traditional mechanical cutting techniques.
Laser cutting also enables fabricators to cut small-diameter holes with advanced detail and high edge quality in sheet, plate, tube, or box sections.
However, there are some disadvantages of laser cutting that we will now explore.
When using the laser cutting method for plastic, the fumes that the plastic produces as it melts are often quite toxic. Basically, this means that the machine will need to be placed in a well-ventilated environment, which can take a lot of time and money to create and place.
The laser cutting method cannot be used for all types of metals. Copper and metal cannot be cut with an optical device because they are too thick and can reflect an excessive amount of light. Brittle and transparent materials, such as glass and crystal, cannot be cut either.
A lot of power is needed to keep the laser optical device cutter running. The precise amount of energy used depends on the type of laser, how much is being cut, the thickness of the material, and also the rate of cut. However, an incredible amount of energy is used, particularly in industrial applications.
While laser cutting could be a fast method, the speed of production will not be as constant on an ongoing basis. It may depend on the type of optical device, the thickness of the material, and the type of material you are trying to cut.
