Parameter Optimization Guidelines
Cutting Speed Optimization
Too Fast: Incomplete cuts, excessive dross, poor edge quality
Too Slow: Excessive heat input, wide HAZ, material warping
Optimal: Complete penetration with minimal heat input
- Start with calculated speed
- Adjust based on cut quality
- Monitor for consistent penetration
Power Level Adjustment
Too High: Wide kerf, excessive melting, poor surface finish
Too Low: Incomplete penetration, inconsistent cuts
Optimal: Just enough power for clean through-cut
- Use minimum power for complete cut
- Increase gradually if needed
- Consider pulsed mode for thin materials
Gas Pressure Tuning
Too High: Turbulent flow, inconsistent cut, material damage
Too Low: Poor dross removal, oxidation, rough edges
Optimal: Smooth laminar flow for clean cuts
- Start with calculated pressure
- Adjust for dross removal
- Consider material sensitivity
Focus Position
Above surface: Wider kerf top, good for thick materials
On surface: Parallel kerf walls, general purpose
Below surface: Narrow kerf top, good for thin materials
- Adjust based on material thickness
- Consider kerf geometry requirements
- Test focus position for optimal results
Material-Specific Cutting Guidelines
Mild Steel
Best Gas: Oxygen for speed, Nitrogen for quality
Typical Speed: 2-15 m/min (depending on thickness)
Power Requirements: Moderate, good absorption
Considerations: Oxide layer forms with O2, clean cuts with N2
Stainless Steel
Best Gas: Nitrogen for oxide-free cuts
Typical Speed: 1-8 m/min (slower than mild steel)
Power Requirements: Higher due to reflectivity
Considerations: Avoid oxygen to prevent corrosion
Aluminum
Best Gas: Nitrogen or compressed air
Typical Speed: 3-20 m/min (high thermal conductivity)
Power Requirements: High due to reflectivity
Considerations: Requires higher power, avoid oxygen
Acrylic/Plastics
Best Gas: Compressed air or none
Typical Speed: 5-50 m/min (very fast)
Power Requirements: Low, good absorption
Considerations: Flame polished edges, low power needed
Cut Quality Troubleshooting
Incomplete Cuts
Causes: Insufficient power, too fast speed, out of focus
Solutions:
- Increase laser power
- Reduce cutting speed
- Check focus position
- Verify gas pressure
Excessive Dross
Causes: Low gas pressure, incorrect speed, poor focus
Solutions:
- Increase gas pressure
- Optimize cutting speed
- Check nozzle condition
- Adjust focus position
Wide Heat Affected Zone
Causes: Excessive power, too slow speed, poor thermal management
Solutions:
- Reduce laser power
- Increase cutting speed
- Use pulsed mode
- Improve heat dissipation
Poor Edge Quality
Causes: Vibration, beam quality, incorrect parameters
Solutions:
- Check machine stability
- Verify beam alignment
- Clean optics
- Optimize parameters
