A study of flank wear in orthogonal cutting with internal cooling

Internal cooling is being paid more and more attention as a means to overcome the limitations of cutting fluids. The purpose of this paper is to investigate the effects of internal cooling on the flank wear of cutting tools in orthogonal cutting. A flank wear model for a cutting tool in orthogonal cutting is presented which is based on previous wear models and includes the normal stress and the effect of thermal softening. The effects of internal heat sink intensity and heat sink area on the flank wear of the cutting tool in orthogonal cutting are demonstrated.
