When casting and machining are purchased from different sources, responsibility can become unclear at the handover. Bracket C is used here to examine raw-part condition, machining stock and inspection ownership. The objective is a complete supplied scope, not a presumption about the bracket’s geometry or load capability.

Define the handover drawing

Identify whether the foundry supplies a raw casting or a partly machined component. Use the appropriate drawing and revision for that condition. Mark locating pads, stock allowances and surfaces that must be suitable for the next operation. The machining company needs enough information to assess the raw part before it commits to finishing work.

Agree where responsibility changes

List which organization checks incoming castings, establishes the finished datum and approves deviations. Decide how a raw-part issue discovered during machining is reported. Avoid a quotation structure in which each company assumes that the other will verify an important feature. The buyer should receive one coherent acceptance package for the delivered bracket.

Protect traceability through processing

Ensure that the part remains identifiable after cleaning, machining and treatment. Specify how heat or batch records connect to finished-part identification. If one raw batch is split across machining orders, retain the relationship in the production records. A material certificate is much less useful when the delivered bracket can no longer be linked to it.

Inspect the condition actually being accepted

Define the measurements required before and after machining. A raw casting report cannot replace inspection of finished interfaces, while a final dimensional report does not explain every raw-material requirement. Where a repair or rework is proposed, agree the approval and reinspection steps. Record the final disposition before shipment.

For Bracket C, request separate casting and machining scopes within a connected delivery plan. Compare related brackets by their functional requirements and production handover, rather than by the short catalogue name.
