Abstract: [Objective] The current study proposed a measure which sliced the reconstituted sector board after star-sawing in longitudinal direction in order to improve the volume ratio of log.[Method] This study firstly conducted a mathematical model on the ideal log model. Then, established face cut board mathematical model from the short trail direction and the long trail direction. On the basis of the established mathematical model of log and face cut board, the optimal star-sawing pattern and sliced face cut board diagram could be established. Finally, this paper calculated volume ratio of log which sliced under two different processes consisting of star-sawing and sliced directly.[Result] The analysis pointed out that the width of slicing face cut board, which perpendicular to the short trail direction, was greater than that perpendicular to the long trail direction. It was reasonable to slice face cut board perpendicular to short trail direction if the veneer's width was required.However, if the veneer's quality was an important factor, it should be cut perpendicular to the long trail direction. The calculated results showed that the volume ratio of log could be improved by new star-sawing sliced technology.[Conclusion] This study demonstrated the theory that star-sawing method can improve the volume ratio of log provided the theoretical support for the actual selection, the volume ratio of log could be improved to a certain degree by choosing larger size log when slicing veneer.
