Machining

Machining is an occupation or hobby that involves using a power-driven machine tool, such as a lathe, milling machine or drill, to shape metal. Machining is a part of the manufacture of almost all metal products. Some plastic parts are machined. A person who specializes in machining is called a machinist.

Most machining operations can be divided into those that remove metal from an item, and those that form metal in an item.

Often an unfinished workpiece will need to have some parts removed or scraped away in order to create a finished product. For example, a lathe is a machine tool that generates circular sections by rotating a metal workpiece, so that a cutting tool can peel metal off, creating a smooth, round surface. A drill or punch press can be used to remove metal in the shape of a hole. Other tools that may be used for various types of metal removal are milling machines, saws, and grinding tools. Many of these same techniques are used in woodworking.
