Kerf, fluence, overlap and power scaling, free
Watch the 2:22 Free Laser Calculators tutorial: Kerf, fluence, overlap and power scaling, free with a step-by-step PDF guide and the tool one click away.
In this tutorial
- Three tabs: Formulas, Universal Scaler and Physics
- Preferred units (MM / IN)
- Pulse Overlap, and the warning when the pulses no longer touch
- Fluence: 60 W, 200 kHz, 0.05 mm spot ≈ 15.28 J/cm²
- DPI ↔ Interval: 300 DPI = 0.0847 mm
- Kerf / Line Offset: a 20 mm square with a 20.15 mm hole = 0.075 mm offset
- Power/Speed Scaler: 40% at 500 mm/s → 80% at 1000 mm/s
- Copy a result with its unit ("Offset: 0.075 mm")
- Universal Scaler: a 60 W recipe on a 110 mm field moved to 50 W and 20 W on a 120 mm field, with the power cap and slower speed when the watts run short
- Physics: heat stacking, the zinc trap in brass, pulse width control
