The question to ask: Can your engineering partner integrate with your existing design environment without creating unnecessary workflow complications?
3. Assess Quality, Accuracy and Design Validation Processes
A fixture that looks correct in a CAD model must also satisfy the functional and manufacturing requirements of the actual production environment.
Design validation is an essential part of BIW fixture engineering.
Evaluate the following:
Accuracy: Are the components positioned correctly according to engineering specifications?
Repeatability: Can the fixture support consistent positioning during repeated production operations?
Strength: Can the design accommodate the forces and conditions associated with the intended manufacturing process?
Durability: Are materials and structural considerations appropriate for the expected operating environment?
Modularity: Can the design accommodate relevant product variations or manufacturing requirements?
Also ask about design reviews, drawing verification, simulation requirements and engineering change management.
These processes help reduce the risk of avoidable design issues and improve confidence before implementation.
4. Look Beyond Design: Evaluate Complete BIW Engineering Capabilities
One of the most important considerations is whether your engineering partner can support the broader manufacturing process.
A narrow fixture design capability may not be sufficient for projects involving complex automotive production systems.
Evaluate the partner’s ability to support related engineering activities such as:
- Process engineering
- Digital plant layout
- Process simulation and virtual manufacturing
- Methods development
- Production planning
- Controls design
- Robot programming
