arbetstycket

Arbetstycket is a Swedish term used in manufacturing and engineering to denote the piece of material that is subjected to machining or other processing. The word is a compound of arbet (work) and stycke (piece or section) and is used in both indefinite and definite forms; the definite singular is arbetstycket. The term is common in metalworking, woodworking, and plastics processing and can refer to the workpiece at any stage of production, from raw stock to finished part.

In a machine shop or workshop, the workpiece is typically secured in a vise, fixture, or chuck and then machined by processes such as turning, milling, drilling, grinding, or shaping. The concept applies across materials, including metals, wood, and plastics. The term emphasizes the object that is being formed or altered, as opposed to the tools or equipment used to perform the work.

Specifications for an arbetstycke include its dimensions, tolerances, surface finish, and material grade. Quality control involves measuring the finished piece with gauges, micrometers, or coordinate measuring machines to verify conformance to drawings and standards. The term thus anchors discussions of design, manufacturing, and inspection within engineering contexts.

Etymology and usage: arbeta relates to work, stycke to piece or section. The term is widely used in Swedish technical literature, education, and industry to describe the part undergoing processing in a production sequence. See also related terms such as cutting tools and fixtures, which interact with the arbetstycket during fabrication.
