Feed Conversion
Feed Conversion
Converts tooth feed, feed per revolution, and feed rate into one another, including imperial units.
How to use the result
Milling cutter catalogues usually specify feed per tooth fz, turning and drilling data specify feed per revolution fn, and the NC program requires vf (G94) or fn (G95), depending on the G-code.
For inch data, IPT, IPR, and IPM correspond to fz, fn, and vf.
Formulas
fn = fz · zvf = fn · n = fz · z · nfz = vf / (z · n)1 in = 25,4 mm Sources: Tabellenbuch Metall: feed in milling and turning; DIN 66025 (G94 feed per minute, G95 feed per revolution)
