Aworkpieceis a piece, often made of a single material, that is being processed into another desired shape[1](such asbuilding blocks).
The workpiece is usually a piece of relatively rigid material such aswood,[2]metal,plastic, orstone.After a processing step, the workpiece may be moved on to further steps of processing. For example, a part can made out ofbar stockand later become part of asemi-finished product.
The workpiece is often attached to the tool being used via ajig[3]orfixture,like for example to amilling machinevia anangle plate,or to a lathe via alathe faceplate.Aviseis another example of a simple type of fixture used to fix workpieces.[4]
A workpiece may be subjected to various cutting operations, liketruing,makingfillets,chamfers,countersinking,counterboring,etc. It may also receive various surface treatments and finishes.
The term "workpiece" has established itself withincraftsand themanufacturing industry,and connects the work or treatment and the object to be treated.
Aworkbenchis often used to hold a workpiece steady during work on it.
