Fiber laser cutting machines are widely used for processing different types of metal materials. However, achieving the best cutting result depends largely on selecting the correct parameters based on material thickness.
This article will guide you on how to optimize laser cutting parameters for better performance.
1. Laser Power Selection
Laser power should match the thickness of the material.
For thin sheets, lower power is sufficient and helps avoid burning. For thicker materials, higher power is required to ensure full penetration.
Using incorrect power may lead to incomplete cutting or poor edge quality.
2. Cutting Speed Adjustment
Cutting speed must be balanced with laser power.
If the speed is too fast, the material may not be cut through. If the speed is too slow, it may cause overheating and rough edges.
Proper speed adjustment improves both efficiency and cutting quality.
3. Assist Gas Selection
Different materials require different assist gases.
Oxygen is commonly used for carbon steel to enhance cutting efficiency. Nitrogen is preferred for stainless steel to achieve clean and oxidation-free edges.
Gas pressure should also be stable for consistent results.
4. Focus Position Optimization
The focus position directly affects cutting performance.
For thin materials, the focus is usually set on the surface. For thicker materials, the focus should be slightly below the surface.
There is no single parameter setting suitable for all situations.
It is recommended to perform test cuts before mass production. Adjust power, speed, and gas step by step to find the best combination.
Conclusion:
Optimizing laser cutting parameters based on material thickness is essential for achieving high-quality results. By properly adjusting power, speed, gas, and focus, users can improve efficiency and reduce defects.
