A computerized bucking trainer for optimally bucking hardwoods

Abstract

The bucking of hardwood stems constitutes the initial manufacturing decision for hardwood lumber production. Each bucking cut creates a log of fixed grade and scale. The grade and scale of each log created by the bucker determines the quantity and quality of potential lumber, which determines the value of the log within a given market. As a result, bucking decisions significantly influence the profitability of the harvesting enterprise and ultimately the efficiency of hardwood resource utilization. Poor choices of bucking cut locations with respect to the log shape, size and defect pattern irreversibly reduce value, profit and efficiency. Within a holistic discussion on felling and bucking hardwoods, F.J. Petro (1975) addresses bucking techniques which may be implemented in order to improve log value and operation profitability. In several chapters, he details the practices of jump butting and jump cutting, defect identification, manufacturing to reduce sweep and crook, and bucking for grade. Through the application of these techniques, optimum logs may be produced and substantial improvements in profitability may be realized. This paper discusses available software that will select the optimal bucking pattern for any given hardwood stem.
