Insert geometry
Correct insert geometry is a very important factor
when using anti-vibration boring bars. The most
recommended insert geometry for successful
anti-vibration use, is a positive geometry insert
with a positive rake angle, as this shape exerts a
lower tangential cutting force when machining.

Choosing the appropriate nose radius of the insert
is also a vitally important consideration. A lower
nose radius is recommended as this configuration
significantly reduces the cutting forces, due to the
lower contact between the insert and workpiece,
which helps to limit and reduce vibration.

A greater nose radius creates much larger radial
and tangential cutting forces that can produce
unwelcome vibrations.
