Abstract
To investigate the influence of substrate treatment on the surface integrity and cutting performance of CVD TiN/MT-TiCN/α-Al2O3/TiN coated inserts, four different process routes were designed to produce the coated inserts. The results indicate that the surface treatment can prominently influence the cutting performance. Compared with the typical production process (route 2), the process (route 4) involving polishing rake face and grinding flank face resulted in a 23.3 % enhancement in tool life during continuous turning and a 17.5 % improvement during interrupted turning. This enhancement was due to the smooth rake face (Sa 123 µm) and the improved coating adhesion on the flank face attained through route 4, which delayed the crater wear during continuous turning and notch wear during interrupted turning.
