Laser cutting is the process in which the laser beam is used to heat the workpiece to the point where the piece is decided precisely, the laser machine includes a high -powered laser and a computer to direct the laser beam to the material to be cut. From there, laser rays melt, evaporate, or burn material along the specified piece line, produce the right edge and neatly cut perfectly for gifts and wall art.
Lasers use CO2 gas mixed with high voltage to make plasma, this is transferred through the cold tube of water into the lens, then requires a laser beam through three more mirrors that are aligned correctly and within half a millimetre.
The beam is then passed through another lens set at the focus length and finally to the material.
Laser lenses can be converted to the desired effect that operators want to achieve, for example general cutting lenses are different from image engraving lenses.
According to Coherent, a company that manufactures laser cutting machines, laser cutting:
"... the concentration of energy in high amounts to a small place that is well defined. The heat energy produced by the laser evaporates the material in this specified small area and gas, or a mixture of gas, such as oxygen, CO2, nitrogen, and/or helium is used to blow the vaporised material out of the kerf (the width of a groove made by the laser beam). The beam's energy is applied directly where it is needed, minimising the Heat Affected Zone (HAZ) surrounding the area being cut."
Laser cutting is the most accurate process for the right cutting in almost all ingredients. Laser cutting is the use of high -powered laser to cut materials for the right specifications specified in the laser cutting machine control software. Digital settings are converted by software and are managed by laser for clean and precise cuts. Laser conversion applications are used to do through cutting, cutting kiss, laser perforation, score, laser etc., laser ablation, laser welding, and drilling.
Laser beams are produced by stimulating reinforcement material, CO2 in some cases, with electricity release or lights in a closed area. After the material is stimulated, the beam is reflected from a partial mirror to collect sufficient energy to escape as a visible light beam. This light beam is directed to the lens that focuses the beam. Beams are used to make piercings before cutting. During cutting, the direction of the beam polarisation must be rotated to ensure a smooth edge. The two main cutting methods are evaporation and melting and blowing. Cutting evaporation using laser heat to carry the surface to the boiling point and burn the hole. The hole gets deeper when the steam erodes the hole wall. Cutting evaporation is ideal for materials that do not melt such as wood, carbon, and thermoset plastic. By melting and blowing, the material is heated until it melts and the melted part is blown away by the gas jet. This is a common process for cutting metals.
Laser cutting has many advantages compared to mechanical cuts.
Lasers can also cut more types of material than mechanical cutting and have control software to ensure accuracy. There are companies such as Twilight Craft, offering professional laser cutting services for all your cutting needs.
