Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.

Kerf = Width. Kerf is defined as the width of material that is removed by a cutting process. It was originally used to describe how much wood was removed by a saw, because the teeth on a saw are bent to the side, so that they remove more material than the width of the saw blade itself, preventing the blade from getting stuck in the wood.

I've seen the forest industry change a lot over the years. In the past, sawmilling was difficult work reserved for only the largest of operations. Millions of logs that didn't fit their production model were left in the forest to waste. This all changed in the 1980s when a revolution began in a small garage in America.

A cant is a piece of wood usually over 2" thick and sawn on at least three sides. Most pallet shops want cants to re-saw into pallet parts because they have more options on what sizes they can cut from them. From Gene Wengert, forum technical advisor: A cant is a partially sawn log with at least one flat side.

Milling is the machining process in which the removal of metal takes place due to the cutting action of a rotating milling cutter.In a milling machine, the cutter is rotating due to workpiece is fed against it.This machine can hold more than one tool at a time. The cutter rotates at high speed, and because of the many cutting edges, it removes metal at a very fast rate.

10. Saw Milling. The saw milling is used to produce narrow grooves or slots on the workpiece. This operation is also used for parting off the workpiece into two equal or unequal parts. The saw milling cutter is used in this operation. In this operation, the width of the cutter is very less than the width of the workpiece. 11.

As a rough rule of thumb, each 1/32" reduction in kerf results in a 2% increase (maybe 2-1/2% if all 4/4) in lumber produced. At $500 per MBF average price for lumber (after drying it would be even more!) from a good grade log, this would mean each 1/32" is worth $10 per MBF. If you saw 100 MBF per year, that is $1000 per year per 1/32".
