By comparing values, yields and piece counts from the reports generated using various
arbor setups, an intelligent choice of arbor setups can then be made.
Production Analysis and Reports
The ability of Opti-Rip to update and retain board data is invaluable for both ongoing and
post production analysis. The operation screen displays information which is relevant to
the decision making process during the production run. Below is a summary of the terms
presented on the main computer screen:
Width: The measured width of the board currently being optimized.
Yield: The yield in percent of the current board being optimized calculated by dividing the
sum of all rip widths in a given combination by the measured width.
Auto-Deduct: The value assigned to the auto-deduct function in the current setup.
Value/M: The processed value of the board in $/MBF currently being optimized based on
the values of the ripped stock it produced. It is the sum of all the produced rip widths times
their respective value divided by the actual measured width of the board.
Deduct: The value assigned to the deduct function in the current setup.
Process Time: The amount of accumulated time that has elapsed during a production run
since starting the new batch. Any pause in board measurement exceeding ve (5) minutes
causes the clock to stop, return to the point of its last board measurement and wait for a
new board to continue.
Average Yield: The running average yield of all the boards within a batch which were
optimized.
Bd. Ft. The accumulated board feet volume of all the boards within a batch that were
optimized. For systems with lineal measurement option only.
Average Value: The running average value of all the boards within a batch that were
optimized.
Most of these statistics are included in the Post Production Report which also lists the
background information specic to this set-up number and production run. The report
contains statistics on both the pre-processed lumber and the ripped widths it produces. It
also identies the nancial out come of the production run by calculating the various costs
and values necessary to make objective comparisons. The following denes the terms
