Analysis & Observations on Cutting 3.175 mm Alder with a Monport Onyx 50W CO2 Laser
Optimal Cutting Settings
After conducting a detailed power and speed test, the best settings for clean and precise cuts on 3.175 mm Alder were observed at 50% to 70% power and speeds ranging from 10 to 20 mm/s. These combinations achieved full penetration while maintaining relatively smooth edges, making them ideal for detailed cuts and production work.
Performance Insights
- Successful Cuts:
The most effective cuts occurred at mid power (50%–70%) with speeds between 10–20 mm/s, ensuring clean separation from the material without excessive scorching. - Shallow or Incomplete Cuts:
At higher speeds (30 mm/s and above), even with 100% power, the laser failed to fully cut through the wood, leaving incomplete cuts. - Ineffective Settings:
Lower power levels (20%) across all speeds was unable to fully cut through, making it more suitable for marking or surface detailing rather than full-depth cuts.
Charring & Overburn Considerations
While slower speeds at higher power (e.g., 5 mm/s at 100% power) resulted in deeper cuts, they also led to significant edge darkening due to prolonged exposure to the laser. This effect may be desirable for a natural wood-burn look but can be reduced by adjusting air assist and using masking.
Key Recommended Settings for 3.175 mm Alder:
- Power: 50% – 70%
- Speed: 10 – 20 mm/s
- Frequency: 20 kHz
- Passes: 1
- Air Assist: Recommended to minimize charring
These settings offer a balance between efficiency and cut quality, making them ideal for laser woodworking, engraving, and crafting projects.
