This is core definition of products for all CutLog functions. Before any optimization you have to define your products using this screen. CutLog must know, which timber sizes it can use during optimization process
Values defined for each boards size depends on settings in screen
Mainly you can define either exact size of board as Thickness x Width or width can be defined as interval between some values. On top of screen is possible to define price and optional comment for core board. In FlexiCut2 is possibility to remove core board. Its price can be defined separately.

In this function are defined dimensions for produced timber separately for each wood species. You can define any number of groups for grouping of dimensions. In optimization function then you have to choose particular group which will be used.
Insert key for inserting group for current species
Delete key for deleting group. Group will be deleted include all size combinations!
F2 key for renaming group
Data are edited directly in screen. After modifying is necessary to push Save button for storing the changes into database. Units of measure are defined in FlexiCut configuration screen and are defined for 4 decimal places. Inch units are defined in decimal format.
For each combination of thickness/width should be defined these parameters:
- invoice thickness/width is size which you have agreed with your customer. Volume on base of this dimensions will be invoiced. If user add new size in list, then Cutting size is counted as invoice size plus shrinkage allowance defined in "Shrinkage allowance" function (see section Shrinkage allowance ).
- Cutting thickness/width is size for calculation of optimization. It calculation base on positions of saw blades. Means, size of fresh sawn wood.
- Allowed position of board (described in particular optimization functions description )
- Middle board - indicates, whether can be this size produced as middle board, if not, then it can't be in middle boards.
- I. pass - indicates, whether this size can be produced as side boards in first pass
- II. pass - indicates, whether this size can be produced as side boards in second pass
- Price middle price of middle board (in prism - green color) per volume unit
- Price side price of side board per volume unit
- Maximum round see explanation below
- Comment for any boards can be added comment.
-
Minimum area of heartwood required - If you enable "False heartwood diameter" in FlexiCut2 (12.8. False heartwood on page 82) then this is minimum area of false heartwood required in board
- Length group - timber optional length group policy Length of Timber

Priority - Timber priority
- Cutting sizes are shown in dierent colors. Base on their comparison to cutting sizes. On the bottom side of frame, there are two buttons:
- Invoice to cutting This function will copy all invoice IN SELECTED GROUP sizes to cutting sizes. It makes them equal
- Recount all cutting sizes This will recount all cutting sizes IN SELECTED GROUP. It will set all width as addition invoice size and particular shrinkage allowance for this wood species. It is not necessary to define shrinkage allowance for every possible size defined here. If program did not find the exact size, it approximates it base on the others. If there is no allowances defined for species, it will not adding it.
This product window can be directly run from optimization functions. In
particular optimization function is button next to group selection. See Figure

Width intervals
first you have to enable this feature in settings menu under products tab
In case, when you choose to define width interval in then width of board is defined in quite different way:
Products width interval definition
In this type of definition, you don't need to define all different width sizes for the same thickness. For example on image 21 are defined for thickness 25mm width from 160mm to 250mm with increment of 10mm, so CutLog will work with sizes: 25x160, 25x170, 25x180,25x190 ... 25x150,25x160mm. Then for example the results can be like in figure below, where are for thickness of 25mm different board widths.
Width interval sample result
- For interval is always width for sawing and invoicing the same
- By default, this interval is applied only to side boards (blue/green ones), but in case you need to apply it also for center (prism) boards, just check "Apply also on center boards" option.
- If you want to define exact size and not interval, then set "Cutting width to" to zero value.
Waney edged boards
For define waney edged board is used field maximum round. For better explanation see the following figure.
T - sawing thickness
R - maximum rounding (R < T) (size of waney)
Waney edged board definition
Timber priority
Timber priority can change the result of optimization. Default priority is 100%.
During optimization is always calculated volume of board in resulted pattern and base of this volume is selected the best pattern as result. Volume of each board in patter is summarized together and compared between other possibilities.
In case you define some timber priority, then volume of board is multiplied by priority prior summarize all boards in pattern. So in case of 50% priority is volume multiplied by 0,5. so it is decreased by 50%. For example one board 20x20 with 100% priority is better than one board 20x25 with 50% priority. Of course, when in result is one board 20x20 and two boards 20x25 with mentioned priority definition, then two boards have better volume after applying defined
priority.
