Laser Cutting Advanced Tutorial 04 - Effect of focal length on cutting effect
After the three influencing factors of power, speed and blowing, the laser cutting advanced tutorial continues to describe the fourth factor that affects laser cutting, the focal length.
The theme of this issue: Laser Cutting Advanced Tutorial 04 - The effect of focal length on cutting effect
parameter settings:
Cutting speed: 20mm/s
Cutting power: 25%
Cutting focal length: 6mm, 18mm, 24mm
Whether to blow: weak blowing
We also know that physics is the measure of the aggregation or divergence of light in an optical system. It also refers to the distance from the center of the lens to the focus of the light when the parallel light is incident. Simply put, the focal length is the distance between the focus and the center point of the mirror. The right focal length can make the best effect. So today, let's talk about the best focal length of Leiyu laser cutting machine.
Comparison of effects:
We can see from the pictures that the difference in values makes the cutting effect very different.
1. As the focal length increases, the slit becomes wider and wider. It can be seen that the slit is very thin when the focal length is 6 mm, but when the focal length is 18 mm and 24 mm, the slit is changed from the original slit. Become a groove. The reason is that the focal length becomes larger and the spot becomes thicker.
2. The depth of the cut will become smaller as the focal length becomes larger. It can be seen that the wood block is cut when the focal length is 6 mm, but when the focal length is 18 mm and 24 mm, there are no cuts on the back. It is. It shows that the change of the spot makes the focused energy weakened and the cutting becomes shallow.
in conclusion:
Through this test, we know that the optimal cutting focal length of Leiyu laser cutting machine is 6mm. At this focal length, the slit is the finest. Of course, the cutting depth is also the deepest under the same power and speed.
But isn't the other focal length values a bit inappropriate except for 6mm? Actually not, we can also use different focal lengths to make a variety of different effects, as shown below:
