· Slot or pocket milling is not recommended, since the chip · Cutting conditions are generally limited by the rigidity and
re-cutting easily occurs. power of the machine and the rigidity of the workpiece.
· Tool overhang length must be as short as possible to avoid When setting the conditions, start from half of the values
chatter. When the tool overhang length is long, decrease the of the standard cutting conditions and then increase the
number of revolutions and feed. value gradually while making sure the machine is running
normally.
