Wood machining processes determine the final quality of the manufactured products. Surface roughness is one of the most frequently used parameters specifying the quality of the surface. The effect of machining parameters and tool wear on roughness is considerable but still not precisely explained, because of numerous factors occurring in the process. Previous research concerned effects of various technological parameters on the roughness in different machining techniques. Furthermore, tool wear was analyzed in case of effect on the surface roughness of wood. The aim of this paper was to define the effect of tool wear and feeding speed on the surface roughness of beech wood using multiple regression analysis. This approach allows to describe these dependences in more precise and systematic way.
Keywords: surface roughness, tool wear, European beech
