Laser cutting speed table by thickness
Enter the speed your machine uses at the thinnest thickness and the thickest for a material. The tool calculates the in-between (and also thinner or thicker) using inversely proportional to thickness, in mm/min and mm/s.

| Thickness | mm/min | mm/s | Pierce (s) |
|---|
Example values. Use your machine’s real speeds, gas, and power. Rows marked “estimated” are outside the entered range.
How the table is calculated
- Between the two thicknesses: speed varies with 1 ÷ thickness (inverse proportional), which follows real cutting behavior better than a straight line
- Outside the range (thinner or thicker): power curve based on the two points you entered
- Pierce time follows the same calculation
- Conversion: mm/s = mm/min ÷ 60
Why not use a straight line between thicknesses
With a straight line, the mid-thickness speed ends up too high on thin sheet, and cut time is underestimated. The inverse calc gives lower speeds in that region, closer to what the machine actually does, so your price doesn’t fall below cost.
The same calculation inside the system
In MakerCutt Factory, you only enter the thinnest and thickest thickness for each material family. When you add a new thickness, speed and pierce time are already suggested and flow straight into machine time, price, and lead time in the quote.

FAQ
What’s the cutting speed for each thickness?
It depends on power, gas, nozzle, and material. Take two thicknesses you cut often, note the machine’s real speed, and the tool fills in the rest.
Does it work for plasma and CNC router?
Yes. The thickness-to-speed relationship is also inverse on plasma and CNC routers; use your machine’s speeds.
How do I convert mm/min to mm/s?
Divide by 60. Example: 3,000 mm/min = 50 mm/s.
