Notes:

• Depths of cut (ap) shown in the table are the allowable maximum

  values.
• Mist cooling or air blow is recommended.
• The maximum number of revolutions of the machine to be used is

  lower than 50,000 min-1, the revolutions and feed rate should be
  modied at same rate.
• Use smallest possible overhang.
