We suggested using the heating temperature of wood-cutting circular saws as the control and forecasting parameter of operability of a circular-saw bench. The temperature measur-ing of a cutting instrument of the indicated type in the lumber sawing process was possible by the method of infrared thermal control. The basic problem of infrared control was a high probability of occurrence of the method error of measurement, the dimensions of which, under certain conditions, made this method unsuitable. In this context the goal of research was to establish the mode of the method error compensation, reducing the difference be-tween the tool and actual temperatures to a minimum. The value of the method error in re-mote temperature measurement by total radiation pyrometers was determined by the accura-cy of taking account of coefficient of thermal emissivity of an object. The coefficient of thermal emissivity depended on numerous factors: the material and temperature of an object and external temperature. As a result of the theoretical research it was found, that there was no reliable information in the reference and methodological sources on the magnitude and nature of changes of radiation coefficient of instrument low-alloy steel applied for a saw blade housing. Therefore, it was decided to conduct an experiment using the method of thermal stimulation. As a result of the experiment it was found, that the coefficient of ther-mal emissivity of a saw blade housing was reduced with increasing heating temperature ranging +30…+100 °C and increased with increasing temperature of the saws work space ranging +10…+20 °C. The coefficient of thermal emissivity for the mentioned temperature ranged when measured by the pyrometers of partial radiation in the spectrum of 8 ... 14 um varied 0.2…0.34. As a result of regression analysis of the experiment we have established the analytic dependences of values of thermal emissivity coefficient on the heating tempera-ture and external temperature in the area of infrared control for circular saws, made from instrument steel of 9ХФ and 80CrV2 brands. Application of regression equations enables to compensate the method error in the radiation temperature control at a level not to exceed 5 %, and they can be used at setting of pyrometers of partial radiation for measuring.
