raakatyöstetty

Raakatyöstetty is a Finnish term used in metalworking and manufacturing to describe a workpiece that has undergone initial shaping operations but has not yet been finished. The word combines raak- meaning raw and työstetty meaning machined or processed, and the term is commonly translated as rough-machined or as-machined in English. The concept designates a part that has the basic geometry and features established but lacks the final surface quality and tight tolerances of finished parts.

Characteristics of raakatyöstetty components typically include a rough surface finish with visible tool marks, possible burrs, and looser tolerances than those required for finished parts. They may not yet be dimensionally stabilized for high-precision applications, and additional processing is usually needed before final use.

Manufacturing context and workflow: parts begin as raw material—such as a billet, bar, tube, or casting—and undergo primary shaping operations like turning, milling, and drilling to achieve the basic form. The result is marked raakatyöstetty to indicate that only roughing or primary machining has been completed. Finishing steps—such as precision machining, grinding, deburring, heat treatment, and surface treatments—are performed later, either in-house or by suppliers, to meet final specifications.

Applications and considerations: raakatyöstetty parts are common in prototyping, early-stage production, or situations where exact surface quality is not immediately critical. Using rough-machined components can reduce initial lead times and tooling costs, but can also require additional steps in assembly and inspection to verify final tolerances and performance.

Notes: practices and terminology vary among companies and industries; some organizations may use alternative terms for the same state.
