Face and peripheral milling are the two basic machine milling techniques. Face milling is the milling of a surface that is perpendicular to the cutter axis and re- moves material radially at the end of the cutter’s center axis. During peripheral
milling, the cutter’s axis lies parallel to the surface of the workpiece. Only the orien- tation of the cutter to the workpiece is important and the orientation of the axes within the workspace is immaterial.
During face milling only a small proportion of the tool’s secondary cutting edges come into contact with the workpiece, resulting in a high-quality milled sur- face. In contrast, peripheral milling uses virtually all of the tool’s main cutting edges and is thus more efficient, which increases the lifespan of the tool. However, the large amounts of material this technique removes increases the amount of force involved, resulting in a lower-quality milled surface.
Peripheral and face milling
To remove material, the tool is forced into the surface of the workpiece. Because a milling tool can only remove a certain amount of material at one time, the machine has to be told the precise location of the workpiece. The amount of material that
can be removed in a single cut depends on the type of material, the type of ma- chine, and the tool you use. The depth of each individual cut (known as cut depth per pass or stepdown) depends on the dimensions of the tool and may have to be
repeated to achieve the desired final depth.
