Abstract
Thermal fatigue and wear are some predominant phenomena contributing to the
damage of tools. Both are strongly related to thermal evolution of the tool. To
predict the lifetime of the hot forging tools, an important issue is then to
determine accurately the temperature field during formation. The temperature of
tools results from heating steps due to contact with the hot workpiece and
cooling steps due to the lubrication and cooling with air. Thermal fatigue may
appear by repetition of these steps leading to damage of the tool. A thermal
periodic regime is reached after a significant number of forging passes and, in
this state, abrasive wear ocurrs. This work aims to compute as efficiently as
possible the thermal periodic regime and to determine the temperature in tools.
Keywords: periodic regime, forging, tools.
