Determination of some characteristics of native tree species growing in different environments

Selecting wood materials in accordance with the place of use and processing them under appropriate conditions contributes to the more efficient use of natural resources. It is known that the place where it grows and the environmental characteristics of this place are effective on the usage performance of wood material. In this study, the surface roughness values (Ra and Rz) of larch (Pinus nigra Arnold) and eastern beech (Fagus orientalis Lipsky) tree species growing in north and south views were determined under various CNC wood machining parameters. Test specimens at feed rates of 1000 mm/min, 1500 mm/min and 2000 mm/min; It is grooved on the Scilled 2040 CNC 3-axis milling machine using a 12 mm diameter HSS (high speed steel) cutter at three different speeds, 12000 rpm, 15000 rpm and 18000 rpm. Ra and Rz roughness parameters were measured on the surfaces obtained after the procedure and the results were evaluated. As a result of the general evaluation, it was found that the lowest Ra value for both tree species was 1000 mm/min feed rate and 18000 rpm speed in larch; In beech, it was observed that it was obtained at feed rates of 1000 mm/min or 1500 mm/min in samples taken from the south view. It was determined that the increased number of revolutions provided a linear decrease in the Ra value in both species, with the lowest Ra values obtained at 18000 rpm. In addition, it was determined that the samples obtained from the southern view provided smoother surfaces for both tree species.
