Introduction / Context:
The bill of materials (BOM) is an essential part of working drawings and product data management. It enumerates all components required to build an assembly, linking item numbers on the drawing to procurement and inventory records.
Given Data / Assumptions:
- An assembly drawing shows balloons with item numbers.
- Each balloon corresponds to a BOM line with part number and quantity.
- Downstream systems use BOM data for purchasing and planning.
Concept / Approach:
A correct BOM includes part numbers, descriptions, quantities, and sometimes reference designations and make/buy status. It may be single-level or multi-level (indented), supporting accurate costing, scheduling, and change management.
Step-by-Step Solution:
Prepare or extract the BOM from the CAD/PLM system.Ensure each item balloon on the assembly matches a BOM line.Verify quantities, revisions, and alternates if applicable.Publish the BOM with the drawing package for manufacturing use.
Verification / Alternative check:
Perform a kit audit prior to build; contents should match BOM items and quantities.
Why Other Options Are Wrong:
Incorrect: BOM does not stand for anything other than Bill of Materials.Bill of Measurements / Build order manifest: These phrases are not standard terminology for BOM in mechanical documentation.
Common Pitfalls:
Mismatch between drawing item numbers and ERP BOM entries.Omitting hardware or consumables necessary for assembly.
Final Answer:
Correct
