The system was entirely assembled on a conventional lathe. A cylindrical bar of a quenched and tempered ABNT D6 tool steel was used as workpiece and a full and uncoated PCBN insert as cutting tool. In order to ensure that the other junctions of the system were kept under room temperature, avoiding undesired voltages, it was built a compensation circuit. Trials were performed from the room temperature to temperature around 400 ºC). The work-tool contact joint was heated with an oxiacetylene flame. During the trials, temperature and voltage signals were collected in order to obtain a representative equation of the system calibration curve which will be used in future work for cutting tool measurement with the work-tool couple used in this investigation.Attribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Temperatura de corteMétodo do termopar ferramenta-peçaCalibraçãobachelorThesisEngenharia Mecânica
