Abstract

The FEM model of TiBN and TiBN/TiN coated cutting tool in milling of H13 steel was developed. Process variables such as temperature 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 uncoated cutting tool, possibly due to surface coatings improving the tribological properties of cutting tools. Coating with good thermal properties also help to improve the thermal behavior of cutting tool.
