A model is developed for predicting the heat that flows into the workpiece during dry drilling processes. The model can be applied to any drill of known geometry. The measured drilling thrust and torque are used as inputs in an oblique cutting analysis, and an advection heat partition model is developed to calculate heat flux loads on a finite element model of the workpiece. Experiments using embedded thermocouples have verified that the model accurately predicts the temperature field in the workpiece for a range of drilling speeds and feeds.
