# 生产成品率计算器

把锯切、干燥、机加工和涂装的成品率串成一个综合出材率——并看清目标产量到底需要多少原木。

从原木到出货成品之间的每一步都在丢材积：制材留下板皮和锯末，干燥带来收缩和降等，机加工产生截头料和刨花。这个计算器把各道工序的成品率相乘成一个综合成品率，逐道工序拆解损失，并把它换算成采购真正关心的问题：生产一立方米成品，我要买多少立方米原木？

## FAQ

木工行业典型的生产成品率是多少？

制材出材率通常为 38-60%（FAO 全球平均约 50%），干燥基本保住材积但会让部分板材降等，机加工到最终尺寸的成品率一般为 70-90%。从原木到成品部件的整条链条，往往落在 25-45%。

累计成品率怎么算？

把各道工序的小数成品率相乘：锯切 55%、干燥 70%、机加工 85%、涂装 95%，得到 0.55 × 0.70 × 0.85 × 0.95 = 31.09%。损失是叠乘的，所以综合成品率总是远低于最低的那一道工序。

生产 1 m³ 成品需要多少原木？

用成品材积除以综合成品率。综合成品率 31.09% 时，每出货一立方米，需要投入 1 / 0.3109 = 3.22 m³ 原木。

哪道工序损失的材积最多？

通常是原木开料：把圆木锯成方边锯材，会有 40-60% 变成板皮、裁边条和锯缝。损失表会显示每道工序的贡献，方便你先攻最大的那一项。
