I. Introduction
In the modern manufacturing industry, fiber laser cutting machines are highly valued for their efficiency, precision, and versatility. 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 talk about the cutting speed and thickness parameters of Raycus fiber laser sources, ranging from 1000W to 15000W, for various metals such as carbon steel, stainless steel, brass, and aluminum.
By comparing the cutting speeds at different power levels and material thicknesses, this guide aims to help you select the most suitable cutting parameters to achieve optimal cutting performance and efficiency. 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 fiber laser cutting machine. A 1000W fiber 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 fiber 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.
III. Interpretation and Analysis of the Above Parameter Tables
1. Relationship between cutting speed and power
(1) Relationship between power and cutting speed
The cutting speed of a laser cutting machine is closely related to its power. The greater the power, the higher the laser energy and the cutting speed increases accordingly. This is because higher power provides more energy to melt and vaporize materials, speeding up the cutting process.
For example:
When cutting 1mm thick carbon steel, the 1000W laser has a speed of 5.5-10 m/min.
