Onefinity CNC Feed, Speed, DOC, and Runtime Calculator

A conservative starting-point calculator for pine, oak, and custom wood conditions. Machine limits stay editable because every Onefinity setup, router, bit, and workholding stack is different.

[!] These settings are conservative starting estimates. Actual results depend on the router or spindle, bit manufacturer, tool stick-out, workholding, machine rigidity, wood condition, grain direction, and toolpath. Start conservatively, test on scrap material, and monitor sound, chips, heat, vibration, and tool deflection.

Warnings & Validation

Specific rule-based checks for machine limits, tool size, geometry, chip load, and setup risk.

    Adjust After a Test Cut

    Change one variable at a time; it makes troubleshooting much easier.

      Saved Presets

      Examples are local starting points only, not manufacturer-guaranteed settings.
