Cutting Speed (Vc)
Vc = (p x d x n) / 1000 (m / min)
d = Diameter Things Work
n = Number of rounds per minute (rpm)
p = Phi = 3.14
Vc Influenced by: a) Material, b) Types of cutting tools,
c) Speed feeds, d) Depth feeds
Speed feeds (F)
F (mm / min) = n (rev / min) x f (mm / rev)
Where: n = (Vc x 1000) / p x d (rev / min)
F = in mm / rotation or mm / min
