A jig is a production device that holds a workpiece in position and guides a tool, such as a drill or tap, to ensure repeatable location during machining or assembly. Work instructions, tooling lists, setup sheets, and quality documents use the term where jigs must be distinguished from fixtures and other workholding equipment, and where workshop naming must remain unambiguous.
Jig appears in machining setup sheets, assembly work instructions, tooling purchase orders, and training manuals for operators. Translators often encounter it in tables listing jig numbers, locating points, clamping sequence, and tool guide positions, where terminology must match the workshop naming system. Some languages have a single term for both jig and fixture, so source distinction is easy to lose.
A common mistake is using the same translation for jig and fixture, even though a jig often guides the tool while a fixture mainly locates and supports the workpiece. In work instructions, this can lead an operator to select the wrong tooling or clamping method. The error also propagates into bills of materials and setup sheets.
The EU Machinery Directive requires documentation in the language of the destination market. Safety-related terms must map exactly to the wording of the governing standard.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
