Sandvik Coromant – How to reduce vibration in metal cutting 45
Entry/exit:
Avoid a situation where the centre-line
or the cutter is in line with the work-
piece edge. In this situation the insert
is leaving cut when the chip thickness
is at its maximum, with very high
shock-loads at entry and exit.
Chip evacuation:
Use compressed air to prevent
recutting of the chips.
In deep cavity milling, this is
especially important.
Notice that a coarse pitch (L) cutter
will have more space to evacuate the
chips.
