• Vc: Cutting speed
• fz: Feed per tooth (Feed per revolution is fz  2 as effective number of teeth is equal to two)
Notes : • Dry cutting (or air-blast) is generally recommended. When chips tend to adhere to the cutting edges such as in
milling stainless steel, use a water-soluble cutting fluid.
• When the cutting width is larger than a half of the cutter diameter or chips tend to stay in the cutting area, use
an air blast to remove chips.
• To get the best of the tool 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.
