Log small end diameter under the bark:
Log quantity, pcs:
Kerf:
Log length:
Timber board thicknesses whitespace delimited: ? Enter the thickness of the timber, delimited by spaces. The timber width to be specified further. You can enter any amount of timber of the different/same thickness. The only limit is log diameter.

Sorting by: ? Sorting means displaying the timber on a log cutting pattern. There are two options for sorting: automatic, and manual. When you choose the second option, DEO, you sort the boards as you see they fit.
Timber price per volume unit:			^³
Waney edge point: ? By definition "waney edged" is: A sawn plank of wood still retaining a natural edge (may include the bark) along one or both sides of the piece of timber. While the "Waney Edge Point" is a distance from a log bottom end to the point where waney edge appears on timber due to logging taper and goes on towards the log small end.
Log Taper per meter(!): ? To be specified per meter/3.3 foot. The taper of a log is the difference in the diameter of a log at its ends, which is due to its natural shape. The diameter gradually becomes less towards a log small end.

The Pi1

Log to Timber Cutting Optimizer

It is a sawmill calculator that gives you estimates of log yield. What is in it for you: maximum value from each foot of wood and fewer costs.

Sawmills employ every means to recover as much yield as possible from each log. We offer an algorithm, which generates a maximum log yield through optimising the sawing pattern.

The Pi1 calculations are performed in two stages.

Stage 1 Cutting a log to given different thickness timber. Pi1 stage 1

Stage 2 Getting final timber sizes from ones pre-calculated in Stage 1.
