Abstract
Roughness of Thermally Modified Wood at Milling. This article deals with plane milling of maple wood with consideration of technological parameters, which are of significant effect on arithmetic mean deviation of the roughness profile Ra of the treated wood surface. The measurement of the surface quality was carried out at several different milling parameters. The process of treatment was influenced by the cutting speed, which varied from 20, 30 a 40 m/s and the feeding speed 4, 8 and 11 m/min. The removal at one passing through the material was 1 mm of thickness. Based on the results, it is possible to state that the thermal treatment of wood has no statistically significant effect on the arithmetic mean deviation of the roughness profile Ra. The most significant effect of the observed factors was caused by the feeding speed. The lowest average values of the arithmetic mean deviation of the roughness profile Ra were found at the feeding speed of 4 m/min. The increase of cutting speed has led to decrease of average roughness, whereas the increase of feeding speed led to the opposite effect.
