Abstract: [Objective] This paper proposed three measures: slicing double-sided, cutting feed optimization and reasonable selection, in order to solve the inefficiency, low-productivity, more deficiency and other problems of traditional methods for producing veneer.[Method] Firstly, this study proposed to improve volume ratio and production efficiency by the use of sided-slicing processing for small-diameter wood (sides-slicing refers to the continuous longitudinal chipping on both sides of small-diameter wood, it would not stop until 20 mm thickness was remained for a fixed core slice; then slicing the fixed core that remained after multiple processing). Secondly,we gave detailed formulas for both short and long trail direction of sliced veneer volume by conducting mathematical modeling and practical calculating on the ideal small-diameter wood, by which the theoretical basis for reasonable cutting feed was founded. Finally, this paper conducted mathematical modeling on the cross-section of small-diameter wood, and gave the corresponding volume ratio formulas,the actual parameters of the small-diameter wood were measured, and the volume ratio was calculated according to the formula.[Result] By the actual analysis of the small-diameter wood's volume ratio, the conclusion came that the increase of the size of small-diameter wood (The object is ideal small-diameter that has no knots, no radial bending), the sliced veneer volume was gradually increased, the larger size small-diameter wood should be chosen when slicing veneer, so that the volume ratio of small-diameter wood could be improved to a certain degree.[Conclusion] When the veneer is prepared, the sides slicing technology can not only save time, but also reduce manpower, as a result,greatly improve the processing efficiency and volume ratio. On the basis of mathematical modeling for small-diameter wood, sliced veneer volume formula in short and long trail direction and the volume ratio formula, the waste of timber resources could be decreased and the economic efficiency would be improved by reasonable selecting, cutting feed and slicing the wood.
