Video Measuring Machine

In today’s manufacturing and quality control industries, accurate measurements are more important than ever. A video measuring machine (VMM) is a non-contact optical measurement system that uses high-resolution cameras, advanced image processing and software-operating automation to correctly measure and inspect components. Unlike traditional measuring devices, VMMs provide high speed, repeatability and highly accurate results, giving them an essential tool for industries that require microscopic precision.

What is a Video Measuring Machine (VMM)?

A video measuring machine is an advanced optical instrument that captures images of an object using digital cameras and sophisticated software algorithms to analyze dimensions, geometric and surface profiles with extreme accuracy. These machines eliminate human error, providing automatic and reliable measurements for small and complex parts.

How Does a VMM Work?

  1. The object is placed at an accurate stage.
  2. A high-resolution digital camera captures an image of the object.
  3. The software processes the image, detecting the edges, shapes and measurements.
  4. The results are displayed on a computer screen with a detailed inspection report.

Key Features of Video Measuring Machines

Non-contact measurement – ensures accurate, damage-free inspection of the components.

High-Resolution Digital Imaging– Capture the fine details using high-resolution digital imaging.

Edge detection and CAD comparison – automatically detects edges and overlay measurements on CAD reference models.

Automatic measurement and reporting – reduces manual work and generates detailed reports for quality control.

Multi-axis movement-provides flexibility in measuring components.

3D measurement capabilities-some advanced VMM provides 3D profile measurements and depth measurement capabilities.

User-friendly software interface-Modern VMMs come with intuitive software, making it easy to integrate with CAD data and analyze results.

Types of Video Measuring Machines

  1. Manual Video Measuring Machines

  • Best for: Ideal for low volume or custom measurement.
