The anatomical structure of wood and cutting direction is an important parameter in determining the strength of the bonded samples. The main aim of this paper is to research the effect of radial and tangential grain cuts on bonding strength width-joint bonded samples. The combinations of the bonded surfaces were tangential-tangential, tangential- radial, and radial-radial. Beech-wood, steamed beech- wood, and thermally modified beech-wood samples were planed referring to a radial and tangential surface structure of wood. After the machining process samples were bonded with PVA-c class D3 glue and researched. The planing machine was Weinig Unimat 500 and the planing tool had four blades at a feed speed of 15 m·min-1. The cutting depth of the machining grip was 1.00 mm and the rake angle of the tool blade was bio γ =15°, at 6000°/min. The diameter of the cutting blade was Φ = 125 mm. The results obtained in this research show that the lowest bonding strength had the combination of two tangential surfaces thermally modified beech wood and the highest was at the combination of tangential beech wood. |
