Cutting temperature is a major factor in controlling the tool wear, surface quality and chip formation mechanics. To understand the exact temperature rise in the tool chip interface has been recognized as an important study in achieving the best cutting performance. In this paper, a numerical model based on the finite difference method is presented to predict the temperature between tool and chip interface in continuous machining process. Continuous or steady-state machining operations in orthogonal cutting are studied by modeling the heat transfer between the tool and chip at the tool rake face contact zone. The shear energy created in the primary zone, the friction energy produced at the rake face chip contact zone in the secondary zone and the heat balance between the moving chip and stationary tool are considered. The primary and secondary zone temperature distribution was solved by a computer program written in FORTRAN using finite difference method. The mathematical model and simulation results are satisfactory compared with experimental measurements reported in the literature.
