In this study, the surface roughnesses of some types of wood materials processed with machine operations were examined. Acacia (Robinia Pseudoacacia L.), pear (Pirus communis L.), chestnut (Castanea sativa Mill.), oak (Quercus petreaLieble) and Toros cedar (Cedrus libani A. Rich) were used at the tests. Sample preparation of wood materials, to the annual rings in tangential and radial direction, 250 mm diameter, 24 and 48 with saw toothed circle feed speed (12 m/min) and number of revolutions (3200 rev/min) were sawed. Surface roughness values were determined according to ISO 4287 principles. As a result, the highest value for the surface roughness was obtained from the oak samples the lowest value was obtained from the pear samples. Furthermore, 24 saw toothed circle gave higher result for surface roughness than 48 saw toothed circle according to the direction tangent to the radial direction. Increasing the number of teeth was lead to decreasing of the surface roughness
