What does machining mean?
Machining is the controlled process of cutting and shaping materials with machines, most often metal but also wood, plastics, composites, and other engineering materials. Operations commonly associated with it include milling, turning, drilling, boring, grinding, and finishing. In manufacturing, machining converts a raw piece of material into a component with specified dimensions, surfaces, and tolerances, often through several precisely controlled stages. The word is especially common in mechanical engineering, toolmaking, metalworking, and CNC production, where it may also refer more broadly to the work performed in a machine shop. Although machine cutting can occur in many industrial settings, machining normally implies the deliberate shaping of a material into a functional or accurately designed part. Its use signals technical precision, industrial production, or skilled craftwork rather than a general act of making something.
nounThe process of cutting, shaping, drilling, or finishing material using a machine, especially metal or wood. It may also refer to the overall work performed by such machines or the workshop where that work is done.
- The process of cutting, shaping, drilling, grinding, or finishing material with a machine.
- The technical work or activity carried out in a machine shop, especially on metal components.
"Precision machining gave the component its exact dimensions and smooth finish."
"The factory uses computer-controlled machining to produce engine parts."
"After several hours of careful machining, the metal had taken on the shape of the original model."
Machining is where raw material becomes a precisely fitted part: heat, pressure, and a moving edge transform an industrial block into something designed to work.

Where does machining come from?
The word derives from the verb machine, which was borrowed from the French word machine and ultimately from the Greek makhina, meaning a device or contrivance. The original sense of machine referred to a device using mechanical power, and the development of machining followed as a name for work performed by machine tools. Machinery, machinist, and related forms belong to the same lexical family.
How machining is actually used
The term is most common in manufacturing, engineering, and metalworking. It is usually a technical or occupational term, though it is readily understood in general contexts.
Easily confused with machining
A machine is the device that performs the operation, whereas machining is the process or work of using such a device to cut and shape material.
Machinery refers collectively to machines and their mechanical components, while machining specifically denotes a manufacturing process involving cutting and shaping.
