Study of the influence of the friction force on the surface roughness of wood particle boards and on tool deterioration

The article examines the problem of the influence of the physical characteristics of particle boards on the friction of the processing tool and its deterioration. The method of applying the thermal force to the surface of particle boards while processing for furniture production is an innovative method that eliminates the main disadvantages of processing with sanding belts, namely: the formation of non-recyclable production waste, waviness, surface woolliness, high power consumption. The method of applying the thermal force and, in particular, the effect of friction and heating temperature on the processing tool requires more detailed consideration. One of the key physical characteristics of particle boards is roughness, which significantly affects deterioration. The frictional properties of the material of the processing tool and their influence on temperature indicators are examined. The particle board as a polymer is deformed under the action of external load and temperature. Therefore, the article objectively defines the requirements for polymers. The brands of particle boards which can be subjected to thermal power processing and their full review are presented. The article reveals the concept of the particle board roughness, which significantly affects the deterioration and friction force of the processing tool. Moreover, it was concluded that physical and mechanical characteristics of particle boards, the roughness of which should not exceed 500 micrometer, have already been sufficiently studied. The theory of the transformation of work into thermal energy as well as the influence of the temperature of the board on the physicochemical properties of the particle boards is presented. The article also presents a method for calculating the dynamic and kinematic characteristics of the thermo-drawing unit of the processing tool used to achieve optimal values of the particle board roughness, and to reduce material consumption for lamination and significantly improve the quality of particle boards.
