1. Introduction
Reduce the cutting forces
Start out by choosing the best available cutting solution. Then,
choose the largest possible diameter and shortest possible over-
hang to minimize deflection.
The next thing to have in mind is that the dampening system should
be as close to the cutting edge as possible, and that the weight in
front of the damper should be as light as possible. Reduced weight
on the cutting tool will minimize the kinetic energy in a potential
vibration. This will make it easier for the tool to dampen vibration,
and thus stretch the maximum overhang for both solid and damped
tools.
By implementing these strategies, you will reduce the force varia-
tions and vibration.
