The laser output power is a parameter directly related to the melting ability of the processed material, and it is necessary to increase the output power according to the requirements of improving the processing ability. The situation of improving processing capability is as follows:

1. Improve the operating speed of laser cutting in Shenyang.

2. Increase the required thickness of the processed sheet metal.

3. Processing high reflectivity materials such as aluminum and copper.

4. Change from short focal length lens to long focal length lens.

5. The focal position changes from the surface of the processed object.

We can determine whether the output energy of the machining conditions used is appropriate based on the cutting surface after machining and the situation of sparks during machining. When the output power is much higher than the standard value, the thermal impact around the incision increases and melting occurs at the corner. And the cut noodle marks become thicker, from top to bottom vertically. If the output power value is much lower than the standard value, the lower part of the incision becomes significantly thicker, becoming a dug in state. Moreover, the amount of residue attached increases slightly, making it difficult to remove. The Mars during the cutting process lags behind in the opposite direction of the cutting progress. The suitable processing output conditions exist within a certain range, and the thinner the processing plate, the wider the range of output conditions. Under appropriate output conditions, the cutting surface has fine streaks, and the lower part moves slightly slower relative to the speed of light.
