2.Adjusting Cutting Parameters

Laser Power and Cutting Speed

For different stainless steel types (such as 304, 316), thicknesses, and properties, adjusting the laser power and cutting speed is critical. Excessive power or speed can result in poor cutting surface quality or even cracks, while insufficient power or too slow a speed can reduce production efficiency. Experimentation and fine-tuning are key to finding the optimal settings.

Gas Pressure and Nozzle Selection

Using the correct gas type and pressure, along with a well-matched nozzle design, is crucial for effectively removing oxides and slag during cutting, ensuring a clean and smooth cut surface. For thicker stainless steel plates, larger nozzles and higher gas pressures are required.

Focal Position

The position of the laser focus significantly affects cutting quality. Generally, the thicker the material, the lower the focus position should be set. Adjusting the focal point can enhance cutting results and minimize burr formation.

Frequency and Duty Cycle

By adjusting the laser pulse frequency and duty cycle, you can balance cutting speed with quality. Higher frequency and duty cycles may increase cutting speed but could degrade the cut surface and result in layering. Adjusting these parameters according to real-time cutting conditions ensures the best outcome.

3.Optimizing the Cutting Path

Path Optimization

Efficient cutting path planning can significantly boost production efficiency and reduce costs. When planning the path, it’s important to minimize empty travel and redundant cuts while taking into account the material’s shape, size, and processing requirements.

Support and Fixation

During cutting, stainless steel materials must be adequately supported and secured to prevent movement or deformation, which can compromise cutting quality.

4.Key Considerations

Coaxial Testing

Before beginning the cutting process, perform coaxial testing to ensure the nozzle is aligned with the laser beam output. This guarantees cutting stability and precision.

Safety Precautions

Laser cutting generates high temperatures and intense light, making safety precautions critical. Operators should wear protective eyewear, clothing, and follow proper safety guidelines.

Maintenance

Regular maintenance of the laser cutting machine, including cleaning lenses, checking nozzles, and adjusting parameters, is essential to ensure smooth operation and cutting quality.
