Lumber recovery in sawmilling is determined by a confusing interaction of several variables. Since no two sawmills are alike, the variables that influence lumber recovery are seldom the same from one sawmill to another. This complexity confuses even those with a wide range of knowledge and experience in sawmilling. Knowing the variables that affect lumber recovery in general can unravel the factors present in a specific mill. The purpose of this report is to identify and show how these factors operate in determining lumber recovery. The focus is on how these factors affect volume recovery. Since value recovery is often affected somewhat differently by these factors, the emphasis on volume should be noted and the points made here not taken out of context. (Author).

Regional Softwood Sawmill Processing Variables As Influenced By Productive Capacity written by Philip H. Steele and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1991 with Forest productivity categories.

The relationship between annual softwood sawmill production and lumber processing variables was examined using data from Sawmill Improvement Program (SIP) studies of 650 softwood mills. The variables were lumber recovery factor (LRF); headrig and resaw kerf width; total sawing variation, rough green size, and oversizing-undersizing for 4/4 and 8/4 lumber; planer allowance; and average log diameter and length. All variables except planer allowance and average log diameter were significantly influenced by annual sawmill production. The conversion efficiency of the mills in terms of most of these variables increased as sawmill size increased but decreased at annual production levels approaching or exceeding 100 million board feet. Study sawmills were grouped by geographic region and annual production class. Weighted values of LRF, sawing, and resource variables were calculated for each region by weighting by the percentage of mills of that production class in each category. Weighted and mean values are presented for each annual production class by region.

This report summarizes the results of lumber recovery studies at four sawmills in western Oregon and western Washington; two dimension mills, one grade mill, and one timber mill were included. Results from individual mills are reported and discussed. The four mills were also combined to approximate "average" conversion of logs to lumber for the region. Recovery information is presented by diameter and log grade for lumber volume, lumber grade, and lumber and log value.
