Dimensional inspection systems

Dimensional inspection uses calibrated imaging to measure visible features without contact and to make an automatic tolerance decision on the line.

Application-led engineering

A vision system engineered around your process.

Measurement performance is governed by resolution, optics, calibration, product restraint and temperature. We define the achievable tolerance from sample trials and a controlled set-up.

We start with representative products, known defects, acceptable variation, line speed and the required response. That evidence determines the field of view, resolution, optics, processing and mechanical design.

What it can inspect

Typical dimensional inspection checks.

Every item below is subject to application proof using the actual product, presentation and production conditions.

Length, width, diameter and height from suitable views

Configured against agreed examples, limits and the required line response.

Hole, edge and feature position

Configured against agreed examples, limits and the required line response.

Gap, flushness and alignment

Configured against agreed examples, limits and the required line response.

Profile, angle and contour

Configured against agreed examples, limits and the required line response.

Assembly spacing and relative position

Configured against agreed examples, limits and the required line response.

Tolerance grading and trend outputs

Configured against agreed examples, limits and the required line response.

Production value

Make the inspection part of the process.

Detection is only useful when the result is delivered to the right control, operator or quality record at the right time.

  • Measure without contacting or marking the product
  • Inspect multiple visible dimensions in one cycle
  • Identify process drift before tolerance is exceeded
  • Export results or summaries where specified
Capture to action

One coordinated inspection workflow.

1

Capture

Trigger a stable image using controlled lighting, suitable optics and repeatable product presentation.

2

Decide

Apply proven rules, measurements or trained models with product-specific acceptance limits.

3

Act

Reject, divert, stop, alarm, guide automation or pass the result to production data systems.

Questions, answered

Vision inspection FAQs

How accurate is vision measurement?

It is application-specific. Field of view, pixel resolution, lens choice, calibration and mechanical stability all contribute, so we prove the method using real samples.

Does vision replace a metrology laboratory?

Not automatically. On-line vision is ideal for controlled production measurements, while formal metrology may still be required for reference and calibration.

Can reflective metal parts be measured?

Often, yes, using appropriate lighting, polarisation, optics and fixturing to produce stable edges.

Start with the product and defect

Let’s prove the inspection before you commit.

Send us samples, images, line-speed information and the defects you need to detect. We’ll recommend the right next step.
