Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.
· The lump of metal can be cold (by metal standards, 1/3 of its melting point) or hot (near the melting point, about the only option if you want to forge iron). Other common processes are casting (pouring liquid metal into a mold) and CNC ( C omputer N umeric C ontrol) machining. The strongest result is usually from forging.
