Timber price per volume unit:
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.
Log Batch Cutting Optimization in a sawmill
How to choose what timber to cut from what log ?
The importance of choosing the right log to make each particular size of timber requires deeper insight into what is important. It's easy to fall into the trap of cutting small dimensional timber out of large logs. Save the large ones for large timber.
1. Pi3 finds the optimal log diameter for each specific timber size. To reach the goal, series of log sizes are recalculated and the highest timber output is set. The process of finding the corresponding log is repeated for each timber size specified by the production program.
2. The optimal cutting pattern for a given timber for a given log is calculated.
Do all your measurements for a batch of logs and then start cutting.
