How To Use: Laser Cut Kerf Tester

The laser beam has width and burns away material during cutting. Without Kerf, joints will be loose. Download the test file to determine the optimal value. (Default recommended: 0.2mm)

Understanding the Kerf Phenomenon

"Kerf" refers to the thickness of the material removed by the laser's heat. This gap is not a fixed number; it fluctuates based on several variables:

• Material Choice: Different materials react differently to thermal processing.
• Machine Variance: Every laser cutter has its own unique beam characteristics.
• Process Parameters: Your specific speed, power, and focus height settings.

One important thing to remember: bigger kerf value = tighter fit.

Recently, Atomm has launched a large number of new generators. There is an important value that many users might not pay much attention to but can greatly affect the final result - Kerf.

For complex structures like the Curved Wave Lamp, success depends on finding a precise kerf compensation value tailored to your unique hardware and material.

This project allows you to bypass guesswork by cutting two interlocking test components. By physically testing how these parts mesh, you can verify the exact offset required for your specific setup.

• Measure Your Material: Use digital calipers to find the exact materialThickness. Always measure the raw material after removing any protective masking or tape to ensure accuracy.

• Define the Range: Set your startingKerf to the lowest compensation value you wish to evaluate.

• Reference Marks: Ensure the numerical labels are set to "Score" or "Engrave." These are vital for identifying which side corresponds to which value after cutting.

• The Fit Test: Once the pieces are cut, pair the sides with identical values.
• Evaluate: You are searching for a "friction fit"—the parts should slide together firmly and stay connected without the need for glue, yet without forcing the material to crack.
