Computer-Controlled Cutting

1. Safety Training

We need follow the rules

1. Proper Training: Ensure you are properly trained on the laser cutter's operation and safety procedures.

2. Wear Safety Glasses: Always wear laser safety glasses, a mask or respirator, and thick gloves to protect your eyes, lungs, and skin.

3. Follow Manufacturer's Instructions: Adhere to the manufacturer's guidelines and safety instructions for your specific laser cutter.

4. Use Safety Interlocks: Never bypass or disable the safety interlocks built into the laser cutter. These interlocks are designed to prevent accidental exposure to the laser beam.

5. Ventilation: Ensure proper ventilation to avoid inhaling harmful fumes produced during cutting.

6. Fire Safety: Keep a fire extinguisher nearby and be aware of the fire risks, especially when cutting flammable materials.

7. Supervise the Machine: Never leave the laser cutter unattended while it's in operation.

8. Keep the Area Clean: Remove any debris or flammable materials from the cutting area to prevent accidents.

9. Logbook: Maintain a logbook detailing who used the laser cutter, the cutting time, and the materials cut.

10. Stay Alert: Always stay focused and alert while operating the laser cutter.

By following these precautions, we can safely harness the power of laser cutting technology for our projects.

2. Group Test

Cutting speed and laser energy

The group tested the relationship between cutting speed and laser energy. The photograph below records the comparison.

Kerf measurement

The group estimated a kerf of approximately 0.3 mm from these test samples, as documented in Le Li’s Week 3 report.
