Quality Assurance Design Guidelines
Mark Critical DimensionsDo not rely on general tolerance notes alone; mark dimensions that affect fit, sealing, alignment or test results.
Define Datum ReferencesClear datum references make inspection more repeatable and reduce ambiguity between buyer and supplier.
Specify Report Needs EarlyRequest inspection reports, material certificates or finish certificates during RFQ, not after parts are completed.
Separate Cosmetic RequirementsVisible surfaces, acceptable marks, color and texture should be defined separately from dimensional requirements.
Use Practical TolerancesApply tighter tolerances only where function requires them; unnecessary tight tolerances increase cost and risk.
Clarify Finish ImpactCoating, anodizing, plating, polishing and blasting can affect fit and should be considered in the drawing.
Provide Assembly ContextMating parts, hardware, sealing surfaces and test fixtures help determine what needs inspection.
Confirm Acceptance CriteriaDefine what is acceptable for burrs, edges, surface marks, packaging and documentation before production.
