Introduction / Context:
A complete working drawing set typically includes assemblies and detail drawings. Detail drawings communicate how to make one part to specification. This question checks understanding of the purpose and contents of a detail drawing in manufacturing workflows.
Given Data / Assumptions:
- The part requires unambiguous definition for fabrication and inspection.
- Dimensions, tolerances, materials, and finishes must be specified.
- Title block and notes reflect applicable standards.
Concept / Approach:
A detail drawing defines geometry, tolerances (size, form, orientation, location), surface texture, material, heat treatment, and finish. This enables any qualified vendor to produce and verify the part without guessing designer intent, supporting quality and interchangeability.
Step-by-Step Solution:
Provide fully constrained dimensions with appropriate datum references.Apply tolerances consistent with function and fit.Specify material, finish, and special processes (e.g., anodize, heat treat).Include notes for edges/chamfers, break-all, and deburr as needed.
Verification / Alternative check:
Use a drawing checklist or drawing standard to confirm nothing essential is missing; run a manufacturability review.
Why Other Options Are Wrong:
Incorrect: Suggests detail drawings do not drive fabrication, which is contrary to practice.True only for plastic parts / Applies only to CNC: Detail drawings apply to all processes, including casting, sheet metal, machining, and additive.
Common Pitfalls:
Ambiguous or missing tolerances causing scrap or rework.Underspecified finishes leading to performance issues.
Final Answer:
Correct
