Abstract :The selection of wood materials in accordance with the place of use and their processing under the most appropriate conditions will ensure the utilisation of natural resources with high efficiency. In the utilisation of wood material, it is known that the characteristics of the place where it grows and the place where it grows affect the properties of the log and timber obtained. In this study, the surface roughness (Ra) values of larch (Pinus nigra Arnold) and eastern beech (Fagus orientalis Lipsky) wood species growing in northern and southern aspects were determined under various machining parameters. The specimens were grooved using a Scilled 2040 CNC 3-axis milling machine at 3 different feeds of 1000 mm/min, 1500 mm/min and 2000 mm/min, 12000 rpm, 15000 rpm and 18000 rpm, using a 12 mm diameter HSS (High-speed steel) cutter. The surface roughness parameter Ra was determined on the surfaces obtained, and the data obtained was evaluated. When evaluated in general, the lowest Ra value for both wood species was obtained at 18000 rpm at 1000 mm/min for larch and 1000 mm/min or 1500 mm/min for beech at a feed of 1000 mm/min or 1500 mm/min for the specimens obtained from the southern aspect. A linear decrease in Ra value occurred for both wood species with the increased number of revolutions. The lowest Ra values were obtained at 18000 rpm. Generally, the samples obtained from the southern aspect direction gave smoother surfaces for both wood species.
