Laser cutting means that because of the good directional, high brightness, good monochromaticity and other characteristics of the laser, the laser beam formed by it irradiates the material, can afford to melt, vaporize, ablate, and form holes. With the relative movement of the beam and the workpiece, the workpiece eventually forms a slit to achieve the purpose of cutting the workpiece.


Laser vaporization cutting is the use of laser beam to heat the workpiece, because of its high energy, so that the temperature can rise rapidly, the material will begin to vaporize. When steam is ejected, there will be incision formation on the material. This kind of cutting requires a large amount of power and power density to complete, mostly used in the cutting process of very thin metal and non-metallic materials. Laser oxidation cutting, using laser as preheating heat source, using oxygen and other active gases as cutting gas, through the joint action of the two forms a cut in the metal. In the process, there will be a lot of heat release, which will also help to save energy consumption.


In laser cutting, it is very important to grasp the cutting progress reasonably. If the cutting progress is too fast, then the incision amplitude will become smaller, and the beam's illumination point will be close, resulting in towing, roughness will become larger, Scraping Slag and other adverse conditions. But if the progress is too slow, the action time of the laser will be longer, the area of the spot, the amplitude of the incision and so on will be larger. As a result, the cutting progress can not keep up with the progress of material ablation, so it will have a negative impact on the cutting effect.
