When performing a dimensional check on a mechanical drawing, which tool is most appropriate for measuring an internal bore diameter to a tolerance of ±0.001 inch?
Answer: Bore micrometer
A bore micrometer provides the precision needed to measure internal diameters to within ±0.001 inch accuracy.
A drawing checker finds that a title block lists 'SCALE: 1:2' but a dimension on the drawing does not match the scaled geometry. What is the correct QC action?
Answer: Flag a dimension-to-geometry discrepancy for the originator to resolve
A discrepancy between annotated dimensions and drawn geometry must be flagged to the originator, as the intent may be in either place.
Which ASME standard governs the checking and interpretation of geometric dimensioning and tolerancing (GD&T) on engineering drawings?
Answer: ASME Y14.5
ASME Y14.5 is the standard that defines GD&T symbols, rules, and their interpretation on engineering drawings.
During a drawing review, an inspector notices that a flatness callout has no datum reference. This is:
Answer: Acceptable — flatness is a form tolerance and requires no datum
Flatness is a form tolerance that controls a surface unto itself and therefore requires no datum reference per ASME Y14.5.
A redline markup on a production drawing shows a hole moved 0.25 inch. Before releasing the revision, QC must verify that:
Answer: The hole's new position does not conflict with adjacent features or minimum edge distances
Moving a feature requires checking for interference with nearby features, wall thickness, and minimum edge-distance requirements.
Which type of drawing review specifically checks that all views are necessary, sufficient, and properly aligned with each other?
Answer: View completeness and projection check
A view completeness and projection check ensures every view shown is required, no views are missing, and orthographic alignment is correct.
A first-article inspection (FAI) report for a machined part shows one dimension is out of tolerance. The correct next step is:
Answer: Reject the part and issue a nonconformance report (NCR)
An out-of-tolerance dimension on a FAI triggers rejection and issuance of an NCR to document the nonconformance and drive corrective action.
