Worked scenario
Forty parts machined, forty parts wrong
End-of-batch inspection converts a first-part error into a whole-batch loss, and the first part could have been checked in two minutes.
3 min read
Inspecting at the end is efficient in labour and catastrophic in risk. Every part in the batch carries whatever was wrong at setup.
First-off is the highest-value check
One part, before the batch runs, against the drawing. It catches setup errors, wrong offsets and misread dimensions — which are the failures that affect the whole batch rather than individual parts.
Recording it is what makes it real
Where first-off is an understood practice rather than a recorded step, it is skipped under pressure, which is exactly when setup errors are most likely.
The customer-facing benefit
Inspection results retained against the job answer quality queries without re-measuring, and increasingly customers ask for them as a condition of supply. A shop that already keeps them is in a stronger commercial position than one that must start.
What changes
- First-off inspection recorded before a batch runs
- In-process checks at defined intervals for longer batches
- Rejections attributed to a cause and a stage
- Inspection results retained against the job for the customer
