In the third week, we begin to know and use the machine. I learned the laser cutting machine in the school very quickly, very happy. It can be cut out a lot of interesting shapes according to the 2D design and combined into different works.

Applications | Creative design, educational field, commercial application |
Parameter | Description |
---|---|
Power | Determines the energy intensity of the laser beam, affecting cutting speed and material thickness processing capability. Higher power results in faster cutting but also increases energy consumption and costs. |
Speed | Controls the speed at which the laser head moves, affecting cutting quality and efficiency. Different materials require different cutting speeds; too fast may result in incomplete cuts, while too slow may cause excessive heating of the material. |
Frequency | The frequency of laser pulses affects the fineness of the cut and the size of the heat-affected zone. For certain materials (such as plastics), appropriate pulse frequency can reduce thermal damage. |
Assist Gas | Used to blow away molten material, keeping the cut clean. Commonly used gases include oxygen, nitrogen, and air. Choosing the right gas can optimize the cutting effect. |
Focal Length | The focal length of the lens system determines the position of the laser beam's focus point, affecting cutting depth and precision. Longer focal lengths are suitable for thick materials, while shorter focal lengths are suitable for fine cutting. |
Completed safety training for the xTool P2 laser cutter, covering:
Material A: 3mm basswood & B: 3mm acrylic
Test different materials for optimal power and speed. First of all, draw a 1*1cm square in the software of the laser cutting machine, the cutting process, set different cutting power and speed for each square, and finally, confirm the best power and speed.
Test results of 3mm thick Tilia wood board, relatively economical and efficient power | speed is set to 80% power, speed 35mm/s.
3mm acrylic plate test results, relatively cost-effective power | speed set to 100% power, speed 10mm/s.
Material | Power | Speed (mm/s) | Quality | Notes |
---|---|---|---|---|
3mm Basswood | 80% | 35 | ✅ Best | Clean edges, minimal charring |
3mm Acrylic | 100% | 10 | ✅ Best | Smooth edges, no melting |
Test the cut of 3mm Tilia wood board, first of all, the laser cutting machine software draws 10 side by side 1*1 squares, after cutting, the square is closely arranged in the gap, and then use the vernier caliper to measure the size of the remaining gap, which is the sum of 11 cuts.
Test conclusion: Using power 80%, speed 35mm/s of 3mm Tilia wood is 16mm.
Basswood Kerf: 0.15mm per cut → Total 1.65mm for 11 cuts.
Design Adjustment: Compensate by offsetting paths by 0.15mm in CAD.
Test joint gaps of different materials. Laser cut the two materials of the comb joint test board, the width difference between the adjacent joints is 0.05mm, and then test with 3mm lime wood and 3mm acrylic plate, respectively, to see which seam is the best.
Material | Ideal Clearance | Fit Quality |
---|---|---|
3mm Basswood | 2.75mm | Snug fit |
3mm Acrylic | 2.50mm | Tight fit |
By cutting different textures, the Linden board can achieve different degrees of bending.
