Automation

Which level of automation fits the inspection task?

Volume alone does not decide. Variants, material flow, clarification cases and support determine the useful scope of automation.

Consider the complete workflow

An automation decision extends beyond measurement itself. Part preparation, identification, positioning, cleaning, reference checks and documentation all belong to the process. Focusing only on probe movement can underestimate the manual work required before and after inspection.

Automated inspection in the material flow

Plan inspection, evaluation and clarification cases as one connected process.

  1. 01

    Identify the component

    Provision and unambiguous assignment

  2. 02

    UT or ET inspection

    Suitable inspection technology and controlled handling

  3. 03

    Evaluate inspection status

    Validity of the inspection and agreed criteria

Inspection valid · criteria met

Release as specified

Consider further release steps.

Deviation or invalid inspection

Quarantine and clarify technically

Initiate a defined re-inspection if required.

Document inspection status and context

Component reference · Program version · Agreed inspection data

Conceptual illustration. The graphic does not replace an inspection or release instruction; releasing a component is subject to the applicable requirements.

Balance flexibility and repeatability

Manual inspection may suit changing tasks and geometries that are difficult to standardise. Semi-automation takes over selected steps and can be a useful intermediate solution. A highly automated process needs controlled conditions and defined responses to faults, variants and invalid inspections.

Evaluate economics under realistic conditions

Assess investment, changeovers, operational support and maintenance alongside the expected throughput. Cases requiring clarification affect staffing needs. Make the assumptions behind a comparison explicit and traceable. General savings claims or an idealised single-cycle time are not a sound basis for a decision.

Practical checklist

  • Record variants and batch sizes
  • Include handling time and changeovers
  • Describe manual interventions and clarification cases
  • Plan operational support and maintenance

Planning example

Illustrative planning example, not a customer reference.

Planning example: A manufacturer with many variants first automates data association and probe movement. Handling remains manual until a sufficiently consistent component family and stable process are available.

Key takeaway

A suitable automation level makes the inspection process controllable. 'Fully automated' is not, by itself, evidence of inspection quality.
