In manufacturing processes, especially metal forming, it is often very difficult to determine what acceptable heat transfer coefficients are at the die workpiece interface; this is a poignant problem often faced by engineers using commercial software to simulate a metal forming situation. This work is part of an ongoing study of the physics of the die-workpiece interface in metal forming. An experimental investigation has been conducted on the temperatures at the interface in metal forming. This work differs from others in that the temperatures are measured directly at the die-workpiece interface. The raison d'etre for this work is the experimental data from these measurements can be used to derive accurate heat transfer coefficients (thermal resistances). For the experiments in this work two flat platens were used as dies with both hot and cold solid cylindrical billets. The results indicate that this method can provide a reliable means of predicting the contact resistance. The experimental results also show that commercial metal forming software accurately predicts the heat transfer conditions, at the metal to die interface, if a heat transfer coefficient is chosen above a minimum value.
