CNC feeds and speeds calculator CNC feeds and speeds calculator

CNC RPM and feed rate calculator

Use the calculator for first-pass CNC settings before checking material and tool recommendations.

Final settings depend on machine rigidity, tool geometry, material, cooling and workholding.

Use the calculator to turn input values into a clear, repeatable result.
Keep units and assumptions visible so the calculation can be checked later.
Copy the result or key numbers for reports, messages or spreadsheets.
Reset to defaults when you want to compare another scenario from a clean state.
Calculators run in the browser and are useful for quick estimates before formal checks.
For finance, health, engineering or legal decisions, verify important results with a specialist or official source.
