Solution
Quality control and inspection
Incoming, first-off, in-process and final inspection in one flow, with instructions and reports that follow along.
The problem
Inspections are done every day, but the results end up in binders, spreadsheets and different systems. That makes it hard to see the whole picture, to show the customer what was inspected and to find the right information when something goes wrong.
The context in production
A part passes several inspection points: incoming inspection of material and bought-in components, first-off after start-up or changeover, samples during production and final inspection before delivery. Each inspection has an instruction, a measuring frequency and a result that must be saved.
When inspections are done on paper or in stand-alone files, the quality of the documentation depends on the person filling it in, and compiling it becomes extra work.
Why it matters
Inspection reports and quality certificates are often part of the delivery. If they take time to produce, or cannot be trusted, they become a bottleneck and a risk.
In a complaint you need to be able to answer quickly what was inspected, when, by whom and with what result.
In principle
From control plan to accepted part
The control plan says what is to be inspected, how and how often. At the inspection each value is compared with its tolerance, and what deviates is saved with its context.
How does a risk in the PFMEA become a check in production?
Illustration · Example dataThe control plan turns the risks into concrete checks: which characteristic, with which method and gauge, how often, and what happens when the requirement is not met.
Step by step
- A risk in the PFMEA concerns the length.
- The control plan specifies that the length is measured with a caliper on every part.
- The reaction plan says what is done if the length is outside: quarantine and sort.
Is the part accepted, and what has to be kept with the value?
Illustration · Example dataEvery value is compared with its own tolerance. A value outside is not just a rejected result: it needs a note and the gauge used, so that it can be investigated and shown afterwards.
Step by step
- Four characteristics are measured on the same part. Each characteristic has its nominal value and its tolerance, for example diameter 12.00 ± 0.05.
- Diameter (12.02), length (47.97) and depth (3.21) are within tolerance and accepted.
- The width is measured at 7.93, below the lower tolerance limit (LSL) 7.95.
- A note on what happened and which gauge was used is saved with the value, so that the deviation can be investigated and shown afterwards.
From today to better
Common challenges, and what a better way of working looks like
What it often looks like
- Inspection instructions are on paper at the machine and are not always the latest version.
- Measuring frequencies are not followed up, so it is unclear whether the inspections are actually done.
- Results are entered twice: first on a form, then in a system.
- Reports to the customer are compiled by hand.
A better way of working
- Each inspection has a digital instruction with characteristics, tolerances and linked documents.
- The result is recorded once, ideally directly from the gauge.
- The measuring frequency is followed up, so it shows when an inspection is late.
- Inspection reports and certificates are produced from the same data that is used in production.
Rektron's approach
How we help
Eyesight Quality Control is built for exactly these inspections: incoming, first and last-off, in-process and final inspection. Parts and characteristics are set up with nominal values and limits, inspection instructions and linked documents. The operator measures and records in the same interface and sees the status against the tolerance limits straight away.
The results form the basis for inspection reports and quality certificates, with a report designer for your own templates.

EyesightInspection instructions, inspection reports and quality certificates, plus your own report templates in a report designer.
Directly connected gauges
EyesightDigital gauges over USB or Bluetooth, so the value lands in the right place straight away.

EyesightEvery measured value is tagged with, for example, operator and serial number. Deviations and production events are recorded in a logbook.
Digital checklists
EyesightSimple checklists for routines such as shift start, changeover and maintenance, also time-scheduled.
Read more →SPC, run rules and alarms
EyesightTrend charts and Xbar-R with control limits set per characteristic, an alarm when a value goes outside the limit, and run rules (Nelson or Western Electric) with the rule number at the point. The run rules apply to manually entered values. Changes of operator, machine or batch can be marked in the trend.

The flow
How it works
- 01
Set up
Part, characteristics, tolerances and instructions are set up once.
- 02
Inspect
The operator measures according to the instruction, with connected gauges or manual entry.
- 03
Follow up
Measuring frequency and results show straight away, also for the quality department.
- 04
Report
Inspection report and certificate are produced from the same data.
What changes
- One place for all inspections and their results.
- Less double entry and fewer typing errors.
- Inspection reports and certificates that are quick to produce and can be trusted.

Situations
Where this becomes relevant
The situations are described without the product: what happens, what should apply and who needs to know what.
Situation
A part measures outside tolerance
At inspection a value lands outside the limit. Is it the part, the process or the measurement?

Changeover to the next part
Tools, programs and settings are changed. When is the first part approved?

Incoming material does not meet requirements
A batch deviates at incoming inspection, or causes problems only in production.

Questions
Frequently asked questions
Can we use our existing inspection instructions?
Yes. The content of your instructions, such as characteristics, tolerances and measuring method, is entered during set-up, and documents can be linked to the part.
Do the operators need a computer at every station?
Eyesight is a web service and is used in the browser. We go through together which equipment suits each station best.
