Abstract: This paper discusses the importance of how to improve the wood processing ratio and value in round wood peeling current situation.The existing problem in round wood peeling is also introduced,which is caused by the incorrect control model and outmoded control method.In order to solve the problem two kinds of mathematical models of round wood with no center peeling are established:speedrotation number model and round wood radiusspeed model.Accordingly,two kinds of models,two kinds of round wood with no center peeling control systems for different conditions are designed.The thickness of wood plates is undercontrolled in round wood rotation cutting process.The thickness range of peeling from 0.35 mm to 2.7 mm and the fluctuant value of peeling thickness under ±0.075 mm are realized.The wood ratio and value are greatly raised.
