dusinage

Dusinage is not a widely recognized technical term in machining literature and is typically encountered as a misspelling or dialectal variant of usinage, the French word for machining. Usinage designates the set of processes that remove material from a workpiece to produce a final shape, dimensions, and surface quality, using machine tools controlled manually or automatically. The scope includes subtractive manufacturing operations such as turning, milling, drilling, boring, reaming, tapping, threading, broaching, grinding, and other material-removal methods depending on the part.

In practice, a machining operation involves selecting a material, determining tolerances and surface finish, choosing appropriate cutting tools, and setting machine parameters such as speed, feed rate, and depth of cut. Common equipment includes lathes for turning, milling machines for milling, drilling machines for holes, boring and reaming tools for accurate holes, and grinding machines for fine finishes. Cutting tools are typically made from high-speed steel or carbide, with coatings to reduce wear. Modern shops often use computer numerical control (CNC) machines and computer-aided manufacturing (CAM) software to program tool paths.

Materials machined range from metals like steel and aluminum to plastics and composite materials, and parts can be simple or highly complex with tight tolerances. Quality is controlled through dimensional inspection, surface finish assessment, and process monitoring to ensure conformance.

Dusinage, when used, generally refers to the same domain as usinage, and context and language should clarify the intended meaning. See also machining, manufacturing, and tooling.
