There are several parameters directly affecting the laser cutter's performance. The major performance parameters are
• Air pressure
The auxiliary air pressure plays a role in blowing off the slag. It also causes the heat-affected zone to cool down. The gas includes compressed air, inert gas, oxygen, and nitrogen. For metals, inert gas is used to prevent the burning risks of the material. While air pressure is high, currents will turn up on the material surface. It causes a part of the material to get weakened. It removes the melted part and makes the cutting gap wider. But, in case of the low air pressure, the melted part would not be blown away.
• Laser power
The laser power size affects the cutting speed, quality, width, and thickness. The amount of power can vary with the cutting mechanism and material.
For instance, materials that have a high melting point, high reflectivity, and good thermal conductivity need intense laser power. The increase and decrease in power will result in overheating and slag hanging. Ultimately, you will find the best processing quality. With the increased discharge voltage, there is a higher laser intensity. Thus, the spot diameter also becomes bigger.
• Cutting speed
The quality of every cut can vary with laser cutting speed. The perfect speed ensures a stable line. No slag will be present at the bottom. When the laser power and gas pressure are stable, you will not find a non-linear inverse connection between the slit width and cutting speed. By raising the speed, the laser energy has a shorter action time.
