We determine the appropriate laser cutting head cutting speed and judge whether the laser cutting processing speed can be increased or decreased based on the cutting spark. When the spark spreads from top to bottom or tilts, it indicates that the cutting speed is too fast. If sparks do not spread and gather together, it indicates that the speed is too slow. The material of the workpiece has a certain impact on the accuracy of laser cutting. In the same situation, the cutting accuracy of different materials may vary slightly. Even for the same material, if the composition of the material is different, the cutting accuracy will also differ.

1. The size of the focused spot of the laser beam in the laser cutting head: The smaller the focused spot of the laser beam, the higher the processing accuracy of the laser cutting head, especially for small incisions, with the smallest spot reaching 0.01mm.

2. The positioning accuracy of the worktable determines the repeatability accuracy of laser cutting processing, and the higher the worktable accuracy, the higher the cutting accuracy.

3. The thicker the workpiece, the lower the accuracy and the larger the cutting seam. Due to the conical shape of the laser beam, the cutting seam is also conical, and the material with a thickness of 0.3mm is much smaller than the cutting seam with a thickness of 2MM.

The consequences of cutting too fast:

1. Possible inability to cut through, sparks spraying randomly.

2. Some areas can be cut through, but some areas cannot be cut through.

3. The entire cross-section is relatively thick, but there is no generation of stains.

4. The cutting section shows an oblique stripe pattern, and the lower half is stained.

The consequences of cutting too slowly:

1. Over melting, the cutting surface is relatively rough.

2. The cutting seam widens and the sharp corners melt completely.

3. Affects cutting efficiency.
