Evaluation of the effect of individual paramaters of oak wood machining and their impact on the values of waviness measured by a laser profilometer
This article deals with determining the effect of different degrees of thermal modification, different cutting speeds (20, 30, 40 m. s-1), different feed rates (4, 8, 11 m. min-1) and different rake angles (15, 20 and 25°) with a 1 mm layer of removed material, on the quality of the surface of the workpiece using the mean arithmetic variation of the waviness profile „Wa“. The release was secured by setting the ruler and firmly holding it in the desired position. The ruler so configured was all the time to milling all the setting options.The article evaluates the process of planar milling of natural and thermally modified oak wood (Quercus cerris). For the evaluation, the samples were thermally modified by the Thermowood process at a temperature range of 160-210°C. The quality of the treated surface was evaluated after the planar milling process. The results obtained from this research show that by increasing the cutting speed during the machining of thermally modified and natural oak wood, we achieve better values of the mean arithmetic deviation of the waviness profile. The values of the monitored characteristic can also be improved by lowering the feed rate and selecting an appropriate rake angle. Thermal modification always lowers the values of the monitored characteristic.
