3D finite element analysis of tool wear in machining

The paper is focused on the 3D numerical prediction of tool wear in metal cutting operations. In
particular, an analytical model, able to take into account the diffusive wear mechanism, was
implemented through a specific subroutine. Furthermore, an advanced approach to model heat transfer
phenomena at the tool–chip interface was included in the numerical simulation. The adopted simulation
strategy gave the possibility to properly evaluate the tool wear. The 3D FEM results were compared with
some experimental data obtained turning AISI 1045 steel using uncoated WCtool; a good agreement was
found out.
