| 摘 要： | The FEM model of TiBN ant TiBNI TiN coated cutting tool in milling of H13 steel was developed. Process variables such as temprature and stress in the coating layer as well as in the substrate were analyzed. The efficacy of the present FEM analysis was verified by conducting controlled milling experiments on AISI H13 to collect the relevant tool life and force data. The results show that the stress in a coated tool can significantly be reduced compared to an uncoated cutting tool, possibly due to surface coatings improving the tribolagical properties of cutting tools. Coatings with good thermal properties also help to improve the thermal behavior of cutting tool.
