Example checks for common components
Start with the feature and requirement, then select a suitable instrument or gauge. These are planning examples for accessible features; availability and the actual inspection method are confirmed for each assignment.
| Component / feature | Method to agree | Record and limitation |
|---|---|---|
| Engine block / machined castingAccessible bore diameter | Bore gauge with the agreed setting reference; specified depths and directions | Individual readings, units, measuring position and the applicable limitsA few diameter readings do not establish the full geometric form of a bore. |
| Engine block / machined castingDeck condition and accessible edges | Visual examination against an approved defect standard; suitable light and viewing access | Defect category, location, reference image and part or lot identityVisible surface findings do not establish internal soundness or crack depth. |
| Connecting rodAccessible small-end or big-end bore | Agreed bore gauge or acceptance gauge, with the specified support and setup | Readings or GO / NO-GO result, gauge ID and checked featureDo not infer centre distance, alignment or full geometry from one bore check. |
| Engine valveStem diameter | Suitable micrometer at the positions and directions defined by the inspection plan | Position-specific diameter readings and drawing limitsSurface condition and valve-head features need their own specified checks. |
| Gear / transmission componentAccessible bore and visible damage | Agreed bore or acceptance gauge; separate visual checks for visible damage and burrs | Feature result plus the location and type of each visible findingThese checks do not verify a gear profile or transmission performance. |
| Plastic or rubber componentAppearance, identification and agreed accessible dimensions | Approved boundary sample; suitable low-force measurement or checking fixture | Visual category and any specified numerical or attribute resultsPart flexibility, temperature and measuring force can affect the result. |
| Passive battery enclosureAccessible mounting feature or seal-face condition | Agreed caliper, gauge or fixture check; separate visual examination | Feature identity, method, result and any visible surface findingMechanical enclosure checks do not establish leak tightness or electrical safety. |

Make the drawing revision the starting point
A component name is not an inspection specification. Identify the part number and revision, the exact feature, its units and limits, and any customer-designated special characteristics. Attach the approved visual standard where appearance matters. If the reference is missing or contradictory, hold that check for clarification instead of creating an acceptance rule at the bench.
Confirm access, setup and measurement assurance
A small tolerance does not automatically make a particular instrument suitable. Agree the range, resolution, contact geometry, setup, setting reference and calibration requirements for the feature. Ensure the part and instrument are ready for the specified method. Where temperature, clamping or measuring force affect the result, define those conditions in the work instruction.
Keep readings, observations and gauge results distinct
A micrometer produces a dimensional reading; a GO / NO-GO gauge produces an attribute result within its intended use; a visual check produces an observation against a reference. Record each in the right form. Avoid turning a visible mark into an unsupported depth measurement or treating a passed gauge check as evidence that every drawing characteristic conforms.
Plan the quantities and the material status
State whether each characteristic is checked on every part or on an approved sample. Keep unchecked, accepted, rejected and held material identifiable. Reconcile physical parts using mutually exclusive status categories. Defect counts need a separate basis because one part may carry several findings.
Use the record for an authorised decision
A usable handover identifies the lot, coverage, criteria, instrument or gauge, finding and unresolved checks. Connect any hold to a tag or container and a named decision-maker. Inspection supplies evidence; the responsible customer or quality authority decides release, concession, rework or return.
