Sandvik Coromant – How to reduce vibration in metal cutting 15
Inserts:
We recommend you use sharp, light cutting inserts with a positive chip
breaker such as the CoroCut – CM or GF geometry or the T-Max Q-Cut
5F or 4G geometry. Also it is beneficial to use thin coated inserts which
will enable a smooth cutting action and produce a minimal radial force.
Grooving applications:
When grooving it is possible to change the application to minimise the
risk of vibration by selecting a smaller insert width and making several
cuts instead of one. The operation can then be finished with a side turning
motion, see fig.
In order to avoid vibrations when machining large, wide grooves, make several
inputs with a narrower insert, (fig A), or groove with a narrow insert and
longitudinal turning (fig B).
