tillverkningsunderlag

Tillverkningsunderlag is a Swedish term used in manufacturing to describe the documentation and data that underpin the production of a product. It encompasses the information required to plan, execute and control manufacturing, from design release to final inspection. The underlag serves as a bridge between product design, engineering and shop-floor operations, enabling repeatable, traceable and compliant production.

Contents of tillverkningsunderlag typically include a materialslista or bill of materials (BOM), process descriptions and routings, arbetsinstruktioner (work instructions) and operation sequences, samt toleranser och kvalitetskrav. It also covers verktygs- och maskinparametrar, samt uppgifter om verktyg, maskiner och deras inställningar. Quality-related documents such as inspektionsplaner (inspection plans), provningsmetoder and acceptanskriterier are often part of the underlag. In addition, production orders (produktionsorder), scheduling data and data necessary for material requirements planning (MRP) or ERP-systemen are included to support planning and execution.

Purpose and use of tillverkningsunderlag include enabling consistent product quality, traceability and compliance with standards. It supports change management, versionkontroll and reproducibility across batches, shifts and sites. Digitalization trends have led many organizations to link tillverkningsunderlag to PLM/PDM systems, CNC-program data, and manufacturing execution systems (MES) to improve data integrity and real-time control.

Relation to related concepts: it is a core component of tillverkningsberedning and is closely tied to design for manufacturability (DfM), production planning and quality assurance. The specific content and format of tillverkningsunderlag can vary between industries and companies.
