The cutting speed of the fiber laser cutting machine depends on the power and material thickness.
The power determines the laser energy. The greater the power, the greater the cutting depth.
But too much laser power can cause smoke and burrs.
Speed can control the time that energy is exposed to the material.
The speed of cutting determines the depth of cutting and the smoothness of the edges.
How to select the appropriate and optimal speed, thickness, and power settings?
In this article, we will use the chart to display the maximum cutting thickness and corresponding cutting speed of the Raycus 1000-15000W fiber laser.
The materials involved are mainly metals, such as stainless steel, carbon steel, brass, aluminum, etc.

Now, let's take a closer look at the parameters for cutting stainless steel.
With a 1000W fiber laser cutting machine, you can cut 3mm thick stainless steel at a maximum speed of 3m per minute.
If you use a 1500W fiber laser cutting machine, you can cut 3mm thick stainless steel at a maximum speed of 4.5m per minute.
For 5mm thick stainless steel, a 1000W fiber laser cutting machine can achieve a maximum cutting speed of 0.6m per minute, while a 1500W laser cutting machine can achieve a maximum cutting speed of 1.5m per minute.
By comparing these parameters, it's clear that higher power allows for faster cutting speeds when working with the same type and thickness of materials.

Different materials can also affect the cutting speed of a laser cutting machine.
A 1000W laser cutting machine can cut 2mm thick carbon steel with a maximum cutting speed of 4m/min, 6m/min for stainless steel, 5m/min for aluminum, and 2m/min for brass.
A 2000W laser cutting machine can cut 3mm thick carbon steel with a maximum cutting speed of 4.2m/min, 5m/min for stainless steel, 4m/min for aluminum, and 3m/min for brass.
Conclusion
The greater the power of the laser cutting machine, the thicker the cutting thickness.
The speed of the fiber laser cutting machine is determined by material thickness and fiber laser power.
The thinner the material, the greater the power, and the faster the cutting speed.
However, the cutting quality depends on many factors, and the cutting speed should also be moderate.
If the cutting speed is too fast, there will be many stripes on the cutting surface.
If the cutting speed is too slow, there will be many burrs on the cutting surface.
If your laser source brand is Raycus, you can refer to the parameter provided in this article for adjustment.
The laser cutting machine with different power is selected according to the type and thickness of the material.
