Agreeing a CNC part inspection report before placing an order
Define critical dimensions, drawing references and inspection records before CNC parts are manufactured.
Start with the drawing, not a generic report
An inspection report is most useful when its measurements can be traced to your drawing. Agree the part number, revision, units and the dimensions to be reported. If numbered characteristics are used, provide the same numbered drawing to the supplier and to the person reviewing the results.
Specify the evidence you need
Clarify whether you need measured values for selected dimensions, a material certificate, a finish certificate or another document. These documents answer different questions. A photograph of a measuring instrument is not a substitute for the agreed dimensional results or evidence of material grade.
Agree sampling and measurement conditions
State whether the requirement applies to every part or an agreed sample, and identify any special measurement method that matters for acceptance. Ask how the supplier will handle dimensions that are difficult to access or verify. Inspection effort and documentation should be included in the quotation scope.
Plan how issues will be resolved
Ask for the report at an agreed stage and identify who reviews it. Define how deviations will be communicated before shipment and who can approve a concession. Do not assume that receiving a report automatically means every contractual requirement has been met.
Keep the record connected to the shipment
Ask for references that connect the report to the relevant order and batch. Keep approved drawings, requirement clarifications and inspection records together. Before an initial order, Henry CNC can help communicate the requested documentation with a prospective machining supplier; the actual inspection scope is agreed for the project.
