Quality requirements.
Production evidence.
Define what must be checked, establish the reference and demonstrate the inspection process under representative operating conditions.
Quality methods.
Applied to the system.
The applicable customer specification, standard edition and project acceptance criteria guide the engineering work.
VDA 5.3 / Optical inspection capability
Plan the evaluation of optical measurement, attribute inspection and image processing, including machine-learning components where applicable.
MSA / Measurement-system analysis
Evaluate repeatability, reproducibility and relevant sources of variation using a method suited to the inspection task.
APQP / PFMEA / Control Plan
Connect product characteristics, process risks, inspection methods and the required reaction plan.
Customer-specific requirements
Translate program requirements for records, release, rework, retention and change control into the system scope.
Equipment & robot-cell safety
Include installation requirements, risk assessment, guarding, hazardous energy and electrical safety in the equipment engineering.
Acceptance includes
the whole process.
Assess the inspection as an installed production system.
Clear quality decisions
Approved samples, defect definitions and reference measurements establish the basis for evaluation.
Representative variation
Evaluate the part, loading, surface condition and operating conditions relevant to the inspection task.
Release & recovery
Verify completed and incomplete checks, failure routing, communication interruptions and authorized recovery.
Continued control
Link results to the relevant recipe and software configuration, with review when the inspection process changes.
Traceability designed
into the workflow.
Make the product history useful for production, quality review and follow-up.
Product identity
Connect the assembly, variant and inspection event.
Inspection results
Associate feature-level results, relevant measured values and supporting records with the product.
Rework & reinspection
Preserve the relationship between the initial finding, correction and subsequent release.
Data handling
Define access, retention, customer interfaces and data ownership within the project agreement.
Performance with
a defined test basis.
Specify the application and evaluation conditions before interpreting an inspection result.
| Evaluation topic | What the review should establish |
|---|---|
| Measurement capability | Feature, datum, tolerance, reference method, repeatability and relevant sources of variation. |
| Defect detection | Defect categories, reference decisions, sample composition, missed defects and unnecessary rejects. |
| Production timing | Included station operations, part variants, processing and communication conditions. |
| Release & recovery | Incomplete checks, lost identity, failed communication, approved recovery and reinspection. |
| Change control | Configuration used in the study and changes that trigger review or revalidation. |
Keep the basis
of the decision controlled.
Quality assurance continues after a model or station is first commissioned.
Representative samples
Document the product family, known defects, acceptable variation and agreed treatment of uncertain cases.
Version-linked results
Record the applicable recipe and software configuration so the result can be interpreted later.
Review meaningful change
Consider new materials, tooling, lighting, configurations and observed error patterns when reviewing continued capability.
Verify before deployment
Use review, evaluation, deployment records and an agreed recovery approach when changing the inspection process.
