UNFINISHED WOOD PRODUCT CUTTING OPTIMIZATION SYSTEM

摘要

A system for estimating a velocity of a stress wave induced in an unfinished wood product such as a log or tree stem is used to maximize the value of wood products produced. An accelerometer is placed against the log while the log is struck with a pneumatic hammer. By monitoring the signals received at the accelerometer, t he velocity of stress wave can be determined. Based on the velocity, an estimate of the modulus of elasticity (MOE) for the wood in the log is made. A price table is selected that relates different sizes of lumber having the determined modulus of elasticity to a current market value. The log is then cut such that the value of the lumber produced is maximized.
