Achieve maximum Q
Choose a
e
between 60%–80% as a starting value if possible.
Reduce the number of inserts to maximize Q. This is particularly
important when using full slot engagement.
Chip evacuation
Use compressed air to prevent re-cutting of the chips. This is
especially important in deep-cavity milling. Notice that a coarse
pitch cutter will have more space to evacuate the chips.
Entry and exit
Avoid situations where the centre line or the cutter is in line with
the workpiece edge. In situations like that, the insert is leaving cut
when the chip thickness is at its maximum, which gives very high
shock-loads at entry and exit.
