Feed & Speed Calculator

Calculate spindle speed and feed from cutting speed, diameter, flute count and chip load.

Two-stage calculation

Basic calculation first. Advanced check second.

Run the simple relationship first, then use the advanced version when the operation needs more variables or machine constraints. The calculators are intentionally stacked, not side by side.

Basic calculation

Basic Feed & Speed Calculator

Calculate spindle speed and feed from cutting speed, diameter, flute count and chip load.

Feed Speed Basic

Enter the values you know. The result is calculated in your browser.

Calculation only. Verify toolmaker data, material grade, engagement, machine limits, workholding and actual cutting conditions before production.

Advanced calculation

Advanced Feed & Speed Calculator

Use the fuller calculator when the dedicated variables and machine constraints matter.

How to use the calculator

Calculate spindle speed and feed from cutting speed, diameter, flute count and chip load. Start with the basic calculation, then move to the advanced check when engagement or machine limits matter. Use the linked references to verify the cutting-data source.
