Influence de l'usinage du bois sur les caractéristiques objectives et sur la perception subjective de l'aspect d'une finition

Abstract : The influence of the operating parameters of wood machining on the quality of a finished surface was established. Several parameters were studied related to the machining operation, to the surface preparation and to the product application. A statistical Taguschi experimental tool was implemented. The quantitative evaluation of the state of the surface was assessed by means of an artificial vision system for the determination of the pseudo-roughness of wood surfaces. Various criteria for evaluating the resulting profile were derived. The undulation Kond and roughness Krug criteria give good correlation with the different qualities of machining. The assessment of the perception of surface state and subjective quality of the finishing will be carried out by means of visual and tactile perception methods. Among the criteria which characterize the state of the surface, a criterion named Ksub was defined which present the best correlation with the results of the subjective analysis.
