Formula

v = π × d × n / 1000

n = 1000 × v / (π × d)

d = 1000 × v / (π × n)

Diameter is in mm, cutting speed in m/min, and spindle speed in revolutions per minute. The diagonal lines show constant RPM; the graph uses the exact formulas, so line positions are approximate to the photographed diagram.
