Abstract : Any wood or panel piece is planed before utilization. To obtain the best surface quality in terms of roughness is generally the main objective because everyone relates the final quality of any wood item to his sensitive perception of the surface brightness or roughness. Most often, the surface is not kept in this primary stage. Sometimes. wood pieces are planed and calibrated to be jointed by glueing. The paper demonstrates that the highest mechanical performance of the glued assembly is not obtained from the best surface quality defined as the lowest roughness. In a first step. different methods of surface roughness measurement are described and compared. Then, surface quality is related to glueing (strain energy release rate) capability. At the same time. surface quality is also studied in function of the planing or sanding factors (cutting speed. feed speed, nature of tool, The existence of optimal machining conditions to prepare a surface for glueing is demonstrated on MDE.
