Log and Lumber Software
Here is a collection of calculators that can be used to estimate the
weight of logs and lumber, lumber yield, and tree value. A handful
of products used in the commercial lumber industry for sawing logs into
boards are also included for good measure.
Log
Weight Calculator
Calculates the estimated weight of a log given species, diameter small
end, diameter large end, and length. WoodWeb. Online calculator.
Lumber and Log
Weights Calculator
Computes the weight of green lumber given species and number of board
feet. Also computes the weight of logs given species and number of
cords. Timber Buyers Network. Online calculator.
Lumber Weight Calculator
Calculates the estimated weight of lumber given species, moisture
content, board feet, width, thickness, and length. WoodWeb. Online
calculator.
Lumber Weight Conversion Calculator
Calculates the weight change of lumber given the wood's before/after
moisture content. WoodWeb. Online calculator.
Tree Value
Estimator
Measures a tree’s worth in dollars based on the quantity and quality of
the expected yield in 4/4 lumber. Handles 12 major hardwood species.
Timber Buyers Network. Online calculator.
Tree
Volume Calculator
Calculates volume given diameter, height, and form class. Timber Buyers
Network. Online calculator.
Formula: How to calculate board feet of wood in a standing
tree or log
First measure the diameter of the tree (or log) at breast height and
the height of the tree up to the minimum merchantable log diameter
(where the tree is approximately 8" to 10" wide). You then compute the
following:
Area = radius^2 * PI
([diameter/2]^2 * 3.14)
Cubic Feet = Area (ft) x Height (ft) /
4 (4 accounts for tree taper)
Board Feet = Cubic Feet * 12
Log Cutting and Management Software
CutLog - Assists sawyers
in obtaining the optimum sawing solution for logs. Enables specification
of various cutting parameters such as the thickness of center cants and
side lumber. Results print out includes lumber sizes and piece count,
log size and yield. TEKL Studio. Windows.
HW
Buck
Hardwood bucking optimization and training tool. Grades and scales logs
which are cut from a virtual tree stem and determines the optimal
bucking pattern that provides the greatest potential value. Michigan
Technological University. DOS and Windows.
Log Pro
Software for log procurement and inventory management.
Track and view all inventory transactions by company and location.
Transaction views provide ticket number, date, volume, cost, revenues,
and market value calculations. Primus Partners Inc. Windows.
Sawmill
A powerful tool for professionals in sawmills and/or timber sales. With
just a couple of clicks one can create and simulate complex sawing
patterns and evaluate existing or new products potential profitability.
Generates key financial figures such as "operating profit on EBIT
level", "ROCE%" and "Rawmaterial (round wood) ability to pay". Romware.
Windows.
SAWSIM
Sawmill simulation program used to model the breakdown of logs in any
sawmill. With over 30 years of development, SAWSIM can be used to answer
virtually any "What if . . .?" question you may have about your sawmill
operations. HALCO Software Systems. Windows.
