短周期工业用材多锯片剖分过程的数学模拟研究

THE MATHEMATICAL SIMULATE RESEARCH OF THE SHORT FELLING CYCLEPOLE-TIMBERS ON SAWING WERE RIPPED BY SLASHER SAW

采用截顶椭圆一抛物面原木数学模型，应用原木的四个实测参数，测定出经多锯片裁分锯剖分的各块毛边板、板皮的精确材积；精确算出锯路的损耗和出材率。应用本文提出的理论，可以设计出简单的多锯片裁分锯数控检测系统，使短周期工业用材加工实现数控化。

Using the ellips-parabolid log model with the four practical measurable parameters, it is measured that the exact volume of all the uncut-boards and clabs cut by the multi-bit ripping edger. The loss of the saw Kerf and recovery have be accurately calculated. By the theroies, a quite simple NC detecting system of the multi-bit ripping eddger will be desinged which made the numerical control for the maching of short cycle wood for timber industry realizable.
