Introduction
Before any wood can be used, it has to be cut from the forest and transported to sawmill where further cutting to marketable sizes is carried out. Even after sawmilling operation, i.e conversion processes, pieces produced from the sawing of the log will still undergo some kind of sawing to bit and pieces in the attempt to produce a work piece.
In the modern day sawing, through improved technology, various machines are now available mainly to cut wood accurately and much faster.
