Evaluation the effect of kiln schedule on warp and surface checking in beech (fagus orientalis Lipsky) at 5 cm thickness

In this research , beech (fagus orientalis Lipsky ) lumbers at 5 cm thickness wereran domically selected and commercially cut down from sari region(Neka choobcompany) ,with three schedule namely T5-C3, T5-C4, T6-C4 were adapted fordrying the lumbers down to the final moisture content of 8% to evalua...
