Description of a customized beam of fiber laser cutting machine

A fiber laser cutting machine is a widely used manufacturing machine that uses a focused high-power fiber laser beam to cut materials into custom shapes and designs. This process applies to a variety of metals, including iron, copper, and zinc, and it can also produce precise, and complex parts without the need for custom-designed tools. So, how does the fiber laser cutting machine customize its laser beam according to different needs of the processing? Please let me introduce that to you in the following contents.

What is fiber laser cutting?

Fiber laser cutting is a thermal cutting method that uses a focused high-power-density laser beam as the main heat source to illuminate the workpiece, it causes the irradiated material to melt, evaporate and ablate or reach the point of ignition. At the same time, the molten material is blown away by the high-speed airflow coaxial with the laser beam, so that the cutting of the workpiece is realized. With the maturity of high-power fiber lasers and the application of perfect technology in recent years, the market and application area of fiber laser cutting machines continue to expand, and the fiber laser cutting machine has already become a hot spot in the industry research and development.

How did the fiber laser cutting machine adjust its laser beam?

So, how does the fiber laser cutting machine adjust its laser beam? Actually, all the works done by the fiber laser cutting machine are controlled by the software of the controlling computer of that machine. There are two main setting parameter ranges in the fiber laser engraving machine controlling software that is decisive to the adjustment and customization of the laser beam, which could be listed as the laser power and the cutting speed. Depending on different types of materials these two settings can all be adjusted to meet the customized needs. For example, the level of laser power has a considerable influence on the cutting speed, slit width, cutting thickness, and cutting quality. The required power depends on the characteristics of the material and the cutting mechanism. For example, materials with good thermal conductivity on the cutting surface, high melting point, and high reflectivity require greater laser power. Further reducing or increasing the power will cause slagging or excessive combustion, which will result in a decline in processing quality. This is the main parameter that must be known when using a fiber laser cutting machine. In addition, as the discharge voltage increases, as the input peak power increases, the intensity of the laser will increase. Therefore, the spot diameter increases, and the slit width increases. As the pulse width increases, the average power of the laser will increase. The width of fiber laser cutting is increased. Generally, as the pulse frequency increases, the cutting seam becomes wider. When the frequency exceeds a certain value, the slit width will decrease. In the laser cutting process, the cutting speed has a great influence on the quality of the cut material. The ideal cutting speed will make the lines of the cutting surface more stable, and there will be no slag on the bottom of the material. When the auxiliary gas pressure is in a non-linear inverse relationship with the laser power, the cutting speed, and the cutting width, when the cutting speed is relatively slow, the laser energy will prolong the action time in the cutting seam, increasing the cutting seam width. When the speed is too slow, The effect of laser beam long workpieces on cutting and cutting will be very different, and the cutting quality and production efficiency will be greatly reduced. This is the main parameter that must be known when using a fiber laser cutting machine. As the cutting speed increases, the time for the laser beam to act on the workpiece becomes shorter. This makes the heat diffusion and heat conduction effect smaller. And the width of the slit is reduced.
