• Vc: Cutting speed<br />
• fz: Feed per tooth (Feed per revolution is fz 2 as effective number of teeth is equal to two)<br />
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<br />
recommended.<br />
• Excessive tool overhang from the toolholder should be avoided to prevent chatter.<br />
