Abstract: Temperature distributions generated during orthogonal machining are computed using the finite element method allowing for variations of thermal properties of the work and tool materials with temperature. It has been found that the effect of such variations from ambient temperature values usually results in a lowering of the shear plane temperature by about 10%. However, the effect on tool-chip interface temperature is very complex and depends on the cutting conditions. Possible variations in the thermal conductivity of carbide tool materials were found to have very significant effects on tool-chip interface temperature and cratering rates. © 1991.
