Apparatus and method for estimating timber stiffness profiles of a log by determining the density profile of a cant

摘要

A method of breaking down a stem, log, cant or slab which comprises or includes the steps; of determining an acoustic velocity value for the stem, log, cant or slab, predicting a stiffness profile across the stem, log, or cant as a function of the acoustic velocity and a density profile across the stem, log, cant or slab, and utilizing the stiffness profile in cutting the stem, log, cant or slab.
