Which of These Are Worth Adopting, and at What Point
Most inspection technology is not limited by its price. It is limited by the data underneath it. A vision system installed on top of a paper record produces a faster version of the same blind spot.
The table below is deliberately unsentimental about sequencing, because the order is what decides whether any of it pays back.
| Technology | What it actually replaces | Precondition before it pays off | What it does not fix |
|---|---|---|---|
| Digital inspection records | Paper forms, and re-typing results into a report afterwards | Part numbers and characteristic lists already exist in digital form to fill the record | Does not create the data. If the drawing and the plan are still on paper, the tablet is a typing surface |
| Machine vision / automated inspection | The visual check of a high-volume, single-part-number run | Volume high enough to amortise programming, and repeatable lighting and part presentation | A functional or dimensional problem, and the defects it was never trained on – often the expensive ones |
| In-line measurement on formed parts | Manual checking of a small number of critical dimensions | A process stable enough that the measurement can feed back rather than only report | Variation the press cannot control – material batch and springback still have to be managed |
| Connected quality systems / cloud records | Emailing spreadsheets and PDFs between supplier and customer | An agreed data format, and a named owner of the data on both sides | A supplier who cannot produce meaningful records in the first place |
| SPC with live limits | Reviewing charts after the run has finished | An operator who can act on the signal, and enough history to set limits that mean something | A process with no natural variation recorded yet – limits set on nothing are decoration |
| Sensors and IoT on the shop floor | Nothing, in most job shops, at the current stage | Data already captured consistently at each step, so the sensor has something to correlate with | The basic record-keeping it is meant to improve. Retrofitting sensors first is the most expensive order |
The honest summary is that the useful first step is unglamorous: get the part number, the drawing revision and the inspection characteristics into a consistent digital form, so that every later technology has something to read. How our inspection records are structured is a concrete example of that shape, and the inspection service overview shows how the checks are wired into the job rather than bolted on.
Frequently Asked Questions
What is a realistic first step for a small or mid-sized shop?
Make the record digital and consistent before making it clever. The step that pays back first is usually the one where the inspection result is captured against a part number at the point of measurement, rather than written on a traveller and typed up at the end of the shift. Everything else – trends, alerts, customer portals – is downstream of that and cannot be built on top of nothing.
Are the claims made about AI inspection realistic?
They are realistic in a narrow band: repetitive detection of defect classes the model has been trained on, at volume, under controlled lighting. They are much weaker on the defects you have never seen before, which by definition are the ones a new part brings. The reasonable use is as a filter that raises throughput on known defect classes, with a human still deciding the reject pile.
Does any of this change what I should ask for in an RFQ?
Yes, and it is worth asking early. Ask what format the inspection record arrives in, and whether the measured values or only a pass mark come with it. A scanned PDF of a tick sheet is not data, and a supplier who can hand over the values in a spreadsheet is giving you something you can put into your own quality system without re-keying it.
