The duty ratio of laser cutting refers to the proportion of the actual cutting time to the total processing time in the cutting process.

The duty ratio is usually affected by the following factors:

1. Processing speed: Processing speed refers to the distance that the laser beam moves on the material per unit time. The higher the processing speed, the shorter the cutting time and the lower the duty ratio.

2. Material thickness: When cutting thicker materials, it may take several cuts to completely penetrate the material. This will increase the cutting time, resulting in a high empty duty. In contrast, cutting thin materials can usually be done in a shorter period of time with a low duty ratio.

3. Cutting path: The complexity of the cutting path also affects the duty ratio. If the cutting path is simple and direct, the laser cutting head can move at a higher speed, thereby reducing the duty ratio. For complex cutting paths, the laser cutting head needs to move several times in different directions, increasing the cutting time and duty cycle.

4. Cutting quality requirements: Sometimes in order to achieve better cutting quality, it is necessary to reduce the cutting speed and increase the time that the laser stays on the material. This can help reduce the slit width and improve the quality of the cutting surface, but also increase the duty ratio.

In general, as far as possible to choose the appropriate processing parameters and a reasonable cutting path, you can minimize the duty ratio under the premise of ensuring quality. For efficient production, reducing the duty ratio can improve cutting efficiency, increase actual processing time, and improve production efficiency.
