Sandvik Coromant – How to reduce vibration in metal cutting 46
Two axis ramping:
One of the best methods to reach a full
axial depth of cut is linear ramping in
the X/Y and the Z axis.
If the correct starting point is chosen,
there is no need for milling away stock
from the ramping section.
Use compressed air to get the chips
out of the cavity.
Milling strategy for opening a cavity
There are several ways to open a cavity. Three common methods can be the
following:
Three axis ramping:
Feeding the tool in a helical shaped
path in the axial direction. It is recom-
mended that the diameter of the hole is
twice the diameter of the cutter.
Remember to check the maximum
ramping angle for the cutter. Use com-
pressed air to get the chips out of the
cavity.
