Resolving Engineering Change Notice Divergence between Overseas CAD Models and Local Chinese SOPs
Enforce engineering changes by locking CMM inspection scripts directly to master CAD revisions and withholding tooling sign-off until local SOPs match.
Process Routing Card
Meaning
Tracking control instrument consists of a physical or digital document that travels with a production lot to monitor its progress through different manufacturing operations. A process routing card specifies the sequence of machines, tools and inspections required to transform raw materials into a finished component.
Operational Sequence
Production planners use this tool to communicate the exact workflow to the staff on the factory floor. The process routing card lists every operation in the correct order and identifies the workstation where the task must be performed. This ensures that no step is skipped and that the parts are processed according to the engineered design.
Quality Traceability
Each operator signs or stamps the document upon completion of their specific task. This makes the process routing card an essential part of the traceability system, as it links the final product to every individual who worked on it and every machine that was used. In the event of a product failure, the card allows for a targeted investigation into the specific point where the error occurred.
Compliance Record
Regulatory bodies and customers often require these documents to verify that the manufacturing process adheres to the approved specifications. The process routing card acts as proof that all mandatory inspections and treatments were performed as scheduled. Storing these records after the product has shipped is necessary for meeting long-term liability and warranty requirements in the manufacturing sector.
Digital versions of the card must be backed up to prevent the loss of historical batch data.
