• Vc: Cutting speed
• fz: Feed per tooth (Feed per revolution is fz  2 as effective number of teeth is equal to two)
Notes : • To get the best of the tool’s performance, use of a high-accuracy, side-lock type toolholder or milling chuck which has a high gripping force is
recommended.
• Excessive tool overhang from the toolholder should be avoided to prevent chatter.
