Abstract :In this paper, the optimization of computer numerical control insert ignore into journalissuearticles values(CNC); drilling parameters was conducted using the Taguchi design method on the drilling holes’ inner surfaces roughness insert ignore into journalissuearticles values(Ra); massive wooden edge-glued panels insert ignore into journalissuearticles values(EGP); made of spruce insert ignore into journalissuearticles values(Picea Orientalis Link.);, beech insert ignore into journalissuearticles values(Fagus Orientalis Lipsky);, Iroko insert ignore into journalissuearticles values(Chlorophora excelsa); and Medium Density Fiberboard surfaced with synthetic resin sheet insert ignore into journalissuearticles values(MDFlam);. Three drilling parameters and their effects on Ra were evaluated. These parameters included spindle speed, feed rate, and cutter type. Surface roughness measurements according to ISO 4287 were performed on the inner surfaces of the holes, and Ra values were obtained. An analysis of variance insert ignore into journalissuearticles values(ANOVA); was performed to identify the significant factors affecting the Ra. Optimum drilling parameter combinations were acquired by analyzing the signal-to-noise insert ignore into journalissuearticles values(S/N); ratio. It is shown that the most ideal result was obtained with a two flutes cutter insert ignore into journalissuearticles values(cutter number 2); at 18000 rpm and feed of 1750 mm/minute for in-hole roughness values of the MDFlam test sample. In the drilling operations performed with a double-entry cutter, the lowest roughness values were obtained in all materials.
