Beschreibung

Since grinding is used to finish flank faces, a cutting edge preparation by means of this same process offers the possibility of finishing an insert in one clamping. On the other hand, cutting edge preparation in the region of insert corner radius demands a new method as a result of machine kinematic limitations. This work presents an investigation of cutting edge preparation of PCBN inserts by grinding and the verification of their applicability in hard turning. Results showed that the used method to prepare edge micro geometries is adequate and asymmetric roundings can increase tool life and compressive residual stresses.
