Engineering review
Material Selection Is Part of the Manufacturing Review
Material choice cannot be evaluated separately from the part itself. Before production, the specified material can be reviewed together with the features that affect manufacturability, finishing and inspection.
- 01
Drawing Requirements
Specified grade, condition and applicable drawing notes.
- 02
Part Geometry
Wall thickness, deep features, bores, threads and machining access.
- 03
Tolerances
Critical dimensions, fits and geometric requirements.
- 04
Surface Requirements
Surface finish, anodizing, plating, coating or other finishing requirements.
- 05
Heat Treatment
Hardness or heat-treatment requirements where applicable.
- 06
Inspection Requirements
Critical features, measurement method and required documentation.
Traceability
Material Documentation When Required
Material and manufacturing documentation can be prepared according to the requirements agreed for the project.
- 01Material Certificates
- 02Certificate of Conformance
- 03Inspection Documentation
- 04Heat-Treatment Records When Applicable
- 05Surface-Treatment Documentation When Applicable
Documentation requirements should be identified during quotation or drawing review so they can be included in the manufacturing plan.
