CD Quality Assurance & Compliance 4

Question 1

A drafter discovers an error on a drawing that has already been released to production. The correct action is to:

Accepted Answer

Initiate a formal engineering change to revise the drawing

Answer

Released drawings can only be corrected through the formal engineering change process.

Question 2

Which tolerance callout would a checker reject as impossible to manufacture economically without justification?

Accepted Answer

A ±0.0001 in tolerance on a noncritical rough casting dimension

Answer

Excessively tight tolerances on noncritical features drive unnecessary cost and should be questioned.

Question 3

The revision history block on a drawing must record, at minimum, the revision letter, date, description of change, and:

Accepted Answer

Approval authority for the change

Answer

Each revision entry requires approval identification to establish accountability and traceability.

Question 4

A drawing references 'MIL-STD-100' but the contract requires 'ASME Y14.100'. What kind of problem is this?

Accepted Answer

An incorrect specification reference that must be corrected before release

Answer

Referencing the wrong governing standard is a compliance defect requiring correction.

Question 5

Why should a drafter avoid duplicate dimensions showing the same feature in two views?

Accepted Answer

A future revision may update one and miss the other, creating a conflict

Answer

Duplicate dimensions risk contradictory values when only one instance is updated during revision.
