Revolotions = n = Vc x 1000   Revs / min
                π x D

*n : Revolotionsı (revs/min)
*Vc : Cutting Speed (m./min)

---------------------------------------------------------------------------

Cutting Speed = Vc = π x D x n   meter / min
                      1000

*D : Workpiece diametre (mm)
*π : Constant (3,14)

-------------------------------------------------------------

Delivery = Vf = n x z x fz  mm / min

*z : Number of tooth
*fz : Delivery per cutting (mm/z)
