Feed Rate Calculator
Calculate milling table feed from RPM, feed per tooth and effective flute count.
A QUICK WALKTHROUGH
How to use this tool
- Enter the values in the stated units.
- Choose decimal places and calculate.
Formula and units
Vf = N × fz × Z; N: RPM; fz: mm/tooth; Z: 1–1000; Vf: mm/min
Scope and limitations
An arithmetic estimate only. It does not select cutting parameters or assess machine capability, tooling, quality, power, chip thinning or operational safety.
Precision and input limits
Enter every value as a finite number greater than 0 and no greater than 1,000,000,000. Effective flute count must be a whole number from 1 to 1,000. Display 0–6 decimal places. JavaScript floating-point arithmetic is used; display rounding does not increase accuracy.
