In the past, many power measurement tests have been carried out based on a large number of different combinations of technological parameters. However, in this paper, the effects of technological parameters and wood properties on the power magnitude of peripheral milling are analysed using experimental design methods, where the effects of the different factors can be tested with a much smaller number of combinations. Therefore, a central composite experimental design was used to plan the experiments. Three different tree species with different densities were milled with three different numbers of cutting knives and three depths of cut at constant feeding speed and rotational velocity. For each milling combination, the power was measured continuously and then the average power was calculated. Based on the measurements, a suitable model was determined that allowed the magnitude of the cutting power to be determined for each combination of technological parameters and wood species tested. The model proved to be suitable, as the deviations between the measured and modelled power values are minimal. wood cutting milling power consumption response surface methodology central composite design razžagovanje lesa rezkanje poraba energije metodologija odzivne površine centralna kompozitna zasnova true false true Angleški jezik Hrvaški jezik Članek v reviji 2025-01-08 03:59:10 2025-01-08 08:04:53 2025-01-09 03:57:59 0000-00-00 00:00:00 2024 0 0 Str. 395-404 iss. 4 Vol. 75 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-01-01 630*82 0012-6772 10.5552/drvind.2024.0173 221227267 RAZ_Merhar_Miran_2024.pdf RAZ_Merhar_Miran_2024.pdf 1 D3A91A24B30CA7B761F5837429DFF841 740d41815ee1267df019320bd2763ace0d55589a0b2e6090fc183de1544dbaf6 025a8134-cd8e-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=197882 https://hrcak.srce.hr/en/clanak/470684 1 d62475f7-cd6b-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=197870 Biotehniška fakulteta 0 0 0
