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)
