20.500.12556/RUL-153551 Effects of cutting parameters and grain direction on surface quality of three wood species obtained by CNC milling Computer Numerical Control (CNC) machines are increasingly popular in the production of furniture and wood products, because they combine high processing quality with short production time. The effective use of CNC machines depends on the processing parameters, which also affects the quality of the processed surface. The aim of this study was to determine the effect of feed rate, cutting direction, and grain direction on the surface roughness of various types of wood. Three European wood species (oak, beech, fir) were cut with a spindle speed of 16,000 rpm and two different feed rates (5,000 and 10,000 mm/min) using end mill tools on the CNC machine. The milling was performed in two cutting directions (radial and tangential) and two grain orientations (0° and 90°). An analysis of variance (ANOVA) was performed to evaluate the impact of the cutting parameters. The surface roughness measurements were taken, and two surface roughness parameters (Ra and Rz) were measured to determine the surface quality of the wood. According to the results of this study, the lowest surface roughness values, milling with the same processing parameters, occurred for oak wood, while the highest values occurred for fir. wood CNC milling surface roughness radial tangential grain direction feed rates les CNC rezkanje hitrost pomika true false true Angleški jezik Slovenski jezik Članek v reviji 2024-01-15 09:43:20 2024-01-15 09:43:21 2024-01-16 03:41:24 0000-00-00 00:00:00 2023 0 0 Str. 127-140 no. 3 Vol. 16(65) 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*81 2065-2135 10.31926/but.fwiafe.2023.16.65.3.9 179184643 RAZ_Ibrisevic_Alen_2023.pdf RAZ_Ibrisevic_Alen_2023.pdf 1 DE3EB74070422E8EB8B2699FAE9DB60B 6c95f838360b878a6ebcdb9811fa32ef31ac705e10a6f0b70bee7d62249034f5 09bddbf4-b383-11ee-88ef-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=179599 https://webbut.unitbv.ro/index.php/Series_II/article/view/6759 1 240b2005-b382-11ee-88ef-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=179598 Biotehniška fakulteta 0 0 0
