Fiber Laser Cutting Thickness & Speed Chart

On the one hand, these problems are related to the laser power, on the other hand, they are related to the cutting speed.

In fact, the question of how to calculate the laser cutting speed is an old question. Most operators with laser cutting machines will find the answer to this question.

In this article, we show you the maximum cutting thickness and corresponding cutting speed of IPG 1000-15000W fiber laser in the form of table. Of course, all the following data are for metal fiber metal cutting, such as carbon steel, stainless steel, aluminum, copper, etc.

In addition, if your laser is not an IPG brand (many laser cutting machine manufacturers will use other brands, such as Amada, TRUMPF and Mitsubishi), the following table can be used for your reference, but you can appropriately reduce the value when actually adjusting the machine parameters until you find the most suitable laser cutting speed.

If you want to know how to select the power of fiber laser cutting machine, you can read this post.

II. Fiber Laser Cutting Thickness & Speed Chart by Power

Note: The parameters marked in red in the table are sampling parameters, which are greatly affected by various factors in actual processing and are only applicable in limited scenarios. Small batch production is not recommended; instead, it is advisable to use higher power lasers for mass production and processing.

Note: For cutting carbon steel with a thickness of 1 or 2 mm (which may vary depending on the power), it is recommended to use air or nitrogen gas. This method offers a faster cutting speed compared to using oxygen, although there may be slight slag formation.

III. Fundamentals of Fiber Laser Cutting

Fiber laser cutting is a precision fabrication process that harnesses high-intensity laser beams to cut materials. It is vital for one to understand the laser source’s characteristics and how different materials interact with this technology.

Laser Source and Wavelength

A fiber laser’s source and wavelength are pivotal in determining its cutting capabilities and the quality of the final output. Typically, fiber lasers operate at a wavelength of around 1.06 micrometers, allowing for a highly focused beam with increased absorption by metals. The wavelength is an intrinsic property that affects the interaction with various materials, impacting the cutting efficiency and speed.

Material Types and Compatibility

Fiber lasers are highly compatible with a variety of metal materials, including:

  • Carbon steel
  • Stainless steel
  • Aluminum
  • Copper

The compatibility between the laser and a material dictates the maximum thickness of the material that can be precisely cut, as well as the speed of the cut. Different materials require specific settings to achieve optimal cuts, which is reflected in the thickness and speed charts for fiber laser cutting. These charts are crucial resources for operators to maximize performance and precision in the cutting process.

IV. Influencing Factors on Cutting Speed

Material Type: Different materials absorb laser energy at varying rates, affecting the cutting speed. Metals with higher reflectivity, such as aluminum and copper, typically require lower speeds.

Laser Power: Higher-powered lasers can cut thicker materials at faster speeds. For instance, a 500W laser might cut 1mm steel at a speed of 10 m/min, while a 3kW laser can achieve 35 m/min for the same material and thickness.

Focus Position: The laser beam needs to be precisely focused. If not properly adjusted, the cutting speed can decrease, impacting the edge quality.

Assist Gases: The type and pressure of assist gases, such as oxygen, nitrogen, or air, influence the cutting speed and the quality of the cut edge
