This paper gives a recommendation of including the measurements uncertainty contribution of the natural thermocouple characteristics in the process of empirical modelling of the average temperature during machining process by turning. It is proposed that the calculated uncertainty value of this source should be a part of the overall uncertainty budget of the coefficients/degrees of the resulting power empirical model. The paper includes results of an example where thermo-voltage vs. temperature
