Manufacturing Work Instructions

Manufacturing Work Instructions (MWI) are the controlled documents — increasingly delivered as interactive 3D, video, and AR overlays — that tell an operator exactly how to perform a routing operation. They are version-controlled, traceable to the MBOM and routing, and the most-touched artifact on the shop floor.

What it covers

• Step-by-step procedure with images, callouts, and inspection criteria.
• Tool, fixture, and consumable lists linked to the routing operation.
• Quality checks and acceptance criteria — first-piece, in-process, and final inspections.
• Digital / interactive forms — 3D PMI, AR overlays via Vuforia, paperless tablet-based delivery.
• Effectivity and revision control so the right version reaches the right operator at the right time.

Relationships (see sidebar)

• Supports Manufacturing Execution, CAM and Manufacturing Planning, and Quality Management.
• Implemented by Siemens Teamcenter, Siemens Opcenter, Dassault DELMIA, PTC Windchill, and PTC Vuforia.
• Tied to the Manufacturing Routing and the Model-Based Definition for 3D-driven instructions.
