Abstract
In this paper, a methodology is presented to estimate the heat flux generated in the contact region between the chip and the tool. In the heat flux estimation, a comparison is made between three methodologies: Classic Sequential Function Specification Method (SFSM), nonlinear SFSM and Time Traveling Regularization (TTR). With the estimated heat flux the temperature distribution in the cut region was calculated, the tool hot spot and the influence of the aluminum oxide and titanium nitride coatings on the tool was analyzed. The estimated heat fluxes had little variation between the different techniques used and the temperature had the biggest difference about 3% in relation to the experimental one. The aluminum oxide coating presented a higher reduction of temperature in the cutting tool when compared to the titanium nitride coating.
