Effect of wood finishing and planing on surface smoothness of finished wood

Abstract

The effect of wood finishing and planning on surface smoothness of finished wood samples of Scots pine (Pinus sylvestris L.) eastern beech (Fagus orientalis L.) and oak (Quercus petraea L.), commonly used woods in the furniture industry in Turkey, was investigated for this study which was carried out in 2006 in the capital city of Ankara in Turkey. Two hundred and forty samples were prepared and processed by planing on the radial and tangential direction to annual rings with 2 and 4 blades. Surface smoothness of the samples was measured according to Turkish Standard (TS) 930. Following that, filling coat and topcoat of polyurethane varnish were applied to surfaces of the samples according to ASTM-D 3023. Then, samples were again subjected to measure for determining the surface smoothness. Statistical data were obtained for surface smoothness from varnished and unvarnished wood samples and it was concluded that finishing increases the surface smoothness. © 2007 Asian Network for Scientific Information.
