A workpiece is a piece, often made of a single material, that is being processed into another desired shape[1] (such as building blocks).
The workpiece is usually a piece of relatively rigid material such as wood,[2] metal, plastic, or stone. After a processing step, the workpiece may be moved on to further steps of processing. For example, a part can made out of bar stock and later become part of a semi-finished product.
The workpiece is often attached to the tool being used via a jig[3] or fixture, like for example to a milling machine via an angle plate, or to a lathe via a lathe faceplate. A vise is another example of a simple type of fixture used to fix workpieces.[4]
A workpiece may be subjected to various cutting operations, like truing, making fillets, chamfers, countersinking, counterboring, etc. It may also receive various surface treatments and finishes.
The term "workpiece" has established itself within crafts and the manufacturing industry, and connects the work or treatment and the object to be treated.
A workbench is often used to hold a workpiece steady during work on it.

Milling operations can be classified as either face or peripheral, depending on where exactly the workpiece is cut. Both types involve the use of a rotating cutting tool, known as a milling cutter, to remove material from a workpiece. As the milling cutter rotates, it presses against the surface of the workpiece, essentially grinding away some of its material in that area.
Face milling and peripheral milling follow the same concept by using a rotating milling cutter to remove material from a workpiece. The way in which they perform this task, however, varies. So, whats the difference between face milling and peripheral milling?
Face milling is a machining process in which the milling cutting is placed perpendicular to the workpiece. The milling cutting is essentially positioned face down towards the top of the workpiece. When engaged, the top of the milling cutting grinds away at the top of the workpiece to remove some of its material.
Peripheral milling is a machining process in which the milling cutter is placed parallel to the workpiece. In other words, the milling cutter is positioned so that the sides of the cutter grind away at the top of the workpiece. This is in stark contrast to face milling in which the very tip of the cutter presses against the workpiece.
When compared to face milling, peripheral milling is more effective at removing large amounts of material from workpieces. This is because it uses the sides of the milling cutter rather than the tip. With face milling, only the tip of the cutter is exposed to the workpiece. While this fine for certain milling applications particularly those that require a minimal amount of material to be removed other applications require a deeper level of material removal. For milling applications such as this, peripheral milling is preferred. As the sides of the milling cutter rotate against the workpiece, it scoops out material from the workpiece, allowing it to remove more material than with face milling.
