Review a part design for manufacturability before release

Review a part or assembly design for manufacturability (DFM/DFA) before it is released. Part or assembly: [description, function, and where it fits in the product] Manufacturing process planned: [e.g. CNC machining, injection molding, sheet metal, casting, PCB assembly, additive] Material: [SPEC] Key features and tolerances: [PASTE drawing notes, critical dimensions, GD&T callouts, surface finishes, wall thicknesses, hole sizes] Annual volume and target cost: [NUMBERS] Our in-house capabilities or supplier limits: [machines, max part size, typical achievable tolerances] Review the design for: 1. Tolerances tighter than the function needs, and the cost or capability impact (compare with typical capability for the process). 2. Process-specific issues, for example: molding (draft angles, uniform walls, undercuts, sink, gate location); machining (deep pockets, small internal radii, thin walls, number of setups, non-standard hole sizes); sheet metal (bend radii, hole-to-bend distances, flat pattern); casting (shrinkage, parting line). 3. Assembly: part count, fasteners that could be eliminated, parts that can be installed wrong (error-proofing by design), access for tools. 4. Inspection: can every critical feature actually be measured with the gauges available? Are datums clear? 5. Material and finish choices that add lead time or cost. 6. Standardization: can we use existing parts, fasteners, or material sizes? Return a table: Feature | Issue | Risk (cost/scrap/lead time/quality) | Suggested change | Impact (high/medium/low) | Needs design engineer approval? Then the top 3 changes to make first. Do not change any requirement that affects function or safety without design engineering approval. Mark assumptions about process capability [CONFIRM WITH SUPPLIER].
