Abstract

Analysis of the phenomena occurring dur-ing the treatment of wood by cutting identified need for research aimed at the optimization of manufacturing con-ditions of parts of the furniture industry. With particular interest are insufficiently investigated transients, in terms of cutting speed, which occur in the processing of com-plex shaped surfaces of open and closed types, such as straight and curly grooves, as well as three-dimensional shaped trimmings. When processed friction materials by cutting work tool on the workpiece causes the formation and evolution of considerable energy in the form of heat. That is why in our studies, special attention was paid to determining the temperature in the cutting zone in the processing tool, which has a different surface roughness. When processing timber almost no reliable research data real distribution of thermal energy due to low thermal conductivity material, as well as the complexity of the temperature measurement process in the cutting zone when processing tool. After analyzing the existing methods for determining the temperature in the cutting zone and through a series of previous experiments, in our re-search we used the method of determining the tempera-ture of artificial thermocouple method. According to the results of experiments built graphical dependence. This led to the conclusion that the temperature in the cutting zone while processing wood, the roughness of the surface depends on the tool is greater than the cutting force. The degree of influence of this factor was determined with the constructed graphical dependence of the temperature, as the roughness function in logarithmic coordinates. The studies allowed to enter the supplement in an empirical equation that is used to determine the temperature in the cutting zone while processing transients in the range of cutting conditions. The paper defines the actual tool blade temperature values by using a tint formed on the surface in the range of the maximum possible temperature in the processing timber. Temperatures that cause treated wood surfaces. The results clearly showed that reducing the friction in the cutting area, by reducing the surface roughness of the tool, possibly lowering the temperature, which is a positive factor. applied for detecting the temperature in the cutting zone while processing transients in the range of cutting conditions.
