Green lumber grade yields from black cherry and red maple factory grade logs sawed at band and circular mills

Abstract

Multivariate regression models were developed to predict green board-foot yields (1 board ft. = 2.360 dm ³) for the standard factory lumber grades processed from black cherry (Prunus serotina Ehrh.) and red maple (Acer rubrum L.) factory grade logs sawed at band and circular sawmills. The models use log measurements of grade, scaling diameter, length, and proportion of scaling defect. They can be used in computer programs related to sawmill simulations, economic modeling, or log-yard inventory systems.
