Cavities, thin walls and datum relationships
Show the complete part and its mounting or mating context. Flag deep cavities, thin walls, threaded features and datum relationships. These features need assessment with the material, available access, workholding and inspection requirements.
The number of axes does not define a guaranteed part size, tolerance or surface result. Those requirements must be addressed for your design and order.
Review an aluminum structure RFQ exampleFeatures and surfaces to identify
- Features that need access from several faces
- Critical relationships between surfaces or holes
- Thin walls, deep cavities or other areas needing review
- Datums and inspection requirements
- Surfaces that must be preserved through machining and finishing
Explain the function of a critical feature. If a dimension or surface can change, identify it explicitly. Proposed changes need your engineering approval.
Confirm material and finish
State the required grade and condition, then identify any finish, masking and documentation. Examples of designations in an RFQ include 6061-T6 and 7075-T6 aluminum, SUS304 and SUS316L stainless steel, and TC4 titanium. These examples do not establish stock or acceptance of every geometry. Availability and suitability need confirmation for the order.
Drawing revision and agreed operations
The quotation must state the material, accepted drawing revision, manufacturing route, inspection scope and delivery terms for your part.
