Cutting Data Calculator

Work out milling speed, feed, metal removal rate and cutting power. Pick a material to load typical starting values for a coated carbide end mill, then adjust them to suit your tool.

Time to cut 100 mm

n = 1000 × Vc ÷ (π × D). Vf = fz × z × n. Q = ap × ae × Vf ÷ 1000. P = Q × kc ÷ 60,000, using a typical specific cutting force for the material ().

Default values are general starting points, not guarantees. Tool maker data, machine rigidity and setup come first, so start conservatively and adjust from there.
