| Abstract: |
| A large amount of cutting heat is produced during the heavy cutting process, and insert life is restricted by the effect of thermal load. The thermal load experiment of cemented carbide SCS, WF and YT15 is carried out, and the results show that the bending strength and fracture toughness of cemented carbide material decrease obviously under cyclic thermal load, while in the cooling process, the material mechanical property changes worse suddenly. The high-temperature mechanical property of SCS is the most stable, and that of YT15 is the worst. Further, a relation model among cutting temperature, cutting parameters and insert life is established. Finally, the measures to improve heavy cemented carbide inserts life are summarized from the aspects of cutting parameters selection, insert optimization design and TiCN, A12O3, TiN complex insert coating. The research results are expected to provide support and reference for heavy cutting technology and insert technology. |
