Thermomechanical modelling of the tool–workmaterial interface in machining and its implementation using the \ABAQUS\ \VUINTER\ subroutine

Abstract : In this paper the complex thermomechanical behaviour at the tool–workmaterial interface in machining has been analysed. The contact behaviour is formulated in the frame of a Lagrangian Finite Element approach. The thermomechanical laws governing the tool–workmaterial interface in machining have been implemented via the \VUINTER\ subroutine of ABAQUS/Explicit \FE\ code. Using this interface, velocity dependent heat partition coefficient of the frictional heat has been implemented. Numerical results (calculated heat flux transmitted into the tool and cutting force) have been compared to experimental ones for different cutting conditions, which are in good agreement. It is shown that different couples of the heat partition and heat transfer coefficients can give the same heat flux transmitted in the tool. In addition, with the new developed \VUINTER\ subroutine, it is possible to implement any mathematical model governing the friction and heat exchange for simulations of complex contact behaviours.
