Choosing the Correct Insert
               Choosing the correct insert can have a big influence on the overall success of vibration damping.
               The main way the insert can improve the machining stability is by minimizing the cutting
               forces. Following the guidelines below should be  your first step to eliminate vibrations:


             1  Choose an entry angle that is as close as possible to 90° to reduce the radial forces to a minimum.


                    90°                            75°                             45°







             2  Choose the smallest insert head angle possible.  This will reduce
               overall cutting forces and increase the clearance.

             3  Choose a small nose radius to reduce the cutting forces and to enable machining
               in a lower depth of cut. (Depth of cut should be larger than the nose radius)



                                  0.2                            0.4                            1.2

             4  Machining depth (ap) should be larger than the nose radius.
