How to correctly set laser cutting parameters (speed, power, focusing)?

Learn how to set it up correctly laser cutting parameters – speed, power and focusing.
This is the key to getting precise, clean and professional laser processing effects
for metal, wood, acrylic and other materials.

Why are correct laser settings so important?

Laser cutting is one of the most modern technologies CNC machining,
widely used in industry, production and precision crafts.
The quality and accuracy of the edges depend directly on cutting parameter settings.
Incorrect speed, power or focus values ​​can lead to burns,
burrs or imperfections.
Learn the rules that will make your laser cutting will be fast, clean and repeatable.

Laser cutting speed – how to choose the optimal value?

Cutting speed is a key parameter influencing quality and efficiency of laser cutting.
Too high a speed causes undercuts and rough edges,
too low, however, may lead to overheating of the material and burning.
To find the optimal setting, run tests on the target material.
For laser cutting of steel a speed of 1–3 m/min is usually used,
while at laser cutting of acrylic values ​​can reach up to 20 m/min.

Laser power – how to match it to the material?

The choice of laser power depends on the type and thickness of the material.
Too low a power causes undercuts, and too high a power causes burns and deformations.
For cutting wood and acrylic 30–50 W is usually sufficient,
while at laser cutting of metal the power used is from 100 W to even 200 W.
Please note that any change in material thickness or type requires recalibration of the power.

Laser beam focusing – precision and edge clarity

Correct laser focusing is the basis for clean and precise cutting.
It involves setting the appropriate distance between the laser lens and the material surface.
Too large a distance blurs the beam, and too small a distance can damage the treated surface.
The most common distance used is 1–3 mm, adjusted to the type of laser, lens and material thickness.

Testing and optimization of laser cutting parameters

Each material behaves differently, so it is worth making test cuts before starting production.
Assess the quality of the edges, surface structure and any discoloration.
Measuring tools such as a technical magnifying glass, micrometer or profilometer will be helpful.
Regular testing allows you to optimize laser settings
and avoid material loss.

Summary – Perfect Laser Cutting Step by Step

The right choice laser cutting parameters – speed, power and focus –
is the key to achieving high-quality processing.
By adjusting the settings to the specific material and performing tests regularly,
you can significantly improve production efficiency and edge quality.
Correct laser settings are a guarantee professional results
and customer satisfaction.
