Optimization Guidelines

Power Optimization

Minimum Power Principle:

• Start with minimum power for complete cut
• Increase gradually to improve speed
• Monitor for quality degradation
• Balance power with gas pressure

Power Density Considerations:

• Thin materials: Lower power density
• Thick materials: Higher power density
• Reflective materials: Higher power required
• Heat-sensitive materials: Pulsed mode

Speed Optimization

Maximum Speed Approach:

• Start with conservative speed
• Increase while maintaining quality
• Monitor for incomplete cuts
• Consider production requirements

Speed Limiting Factors:

• Material thickness
• Quality requirements
• Corner geometry
• Acceleration limits

Gas Optimization

Gas Selection Criteria:

• Oxygen: Carbon steel, fast cutting
• Nitrogen: Stainless steel, aluminum, oxide-free
• Argon: Titanium, reactive materials
• Air: Cost-sensitive applications

Pressure Optimization:

• Start with recommended pressure
• Adjust based on dross formation
• Consider gas consumption costs
• Monitor for blow-out effects

Quality Troubleshooting Database

Edge Quality Issues

Rough Edges:

• Cause: Incorrect focus position
• Solution: Recalibrate focus
• Prevention: Regular focus checks

Excessive Dross:

• Cause: Speed too slow, pressure too low
• Solution: Increase speed or pressure
• Prevention: Parameter optimization

Burn Marks:

• Cause: Excessive heat input
• Solution: Increase speed, reduce power
• Prevention: Heat management

Dimensional Issues

Taper:

• Cause: Beam alignment, nozzle alignment
• Solution: Professional alignment
• Prevention: Regular calibration

Oversize Parts:

• Cause: Excessive kerf width
• Solution: Optimize parameters, kerf compensation
• Prevention: Process validation
