In today’s competitive manufacturing landscape, precision, speed and efficiency are more important than ever. Traditional contact-based measurement methods are increasingly being replaced by non-contact metrology, a faster, more accurate and non-destructive way of inspecting complex components.
This blog explores the key techniques used in non-contact metrology, the benefits for manufacturers and how VICIVISION UK’s industry-leading optical measurement systems are transforming turned part measurement across the UK.
What is Non-Contact Metrology?
Non-contact metrology refers to the process of measuring physical objects without touching them. Using technologies such as optical sensors, laser scanners and machine vision systems, it enables high-speed and highly accurate dimensional analysis without the risk of damaging the part.
For industries such as aerospace, automotive, medical and precision engineering, non-contact measurement offers a future-proof solution for inspecting tight tolerances and fine geometries, especially in high-volume production environments.
Key Techniques in Non-Contact Metrology
There are several non-contact techniques used in modern metrology systems, each offering unique benefits depending on the application:
1. Optical Measurement
Optical measurement is one of the most widely used non-contact techniques. It uses cameras, lenses and light sources to capture dimensional data. VICIVISION machines utilise advanced telecentric optics and high-resolution matrix cameras to deliver micron-level accuracy, even on the smallest turned parts.
2. Laser Scanning
Laser scanning projects a laser beam onto a part’s surface to capture its shape in three dimensions. While highly effective for surface profiling, it is less suitable for ultra-precise internal geometries compared to optical systems.
3. Structured Light and White Light Interferometry
These advanced optical methods are often used for complex surface analysis and flatness measurements. They offer excellent resolution and are ideal for micro components and delicate materials.
The Benefits of Non-Contact Measurement in Manufacturing
Switching to non-contact metrology provides significant advantages over traditional measurement systems, particularly for turned components and cylindrical parts.
✔ Faster Cycle Times
Contact methods like CMMs (Coordinate Measuring Machines) can take several minutes per part. VICIVISION systems capture thousands of data points in a matter of seconds, reducing inspection time and increasing throughput.
✔ Increased Accuracy and Repeatability
Optical systems are not affected by probe pressure or operator variation. This results in more reliable measurements, especially when dealing with complex geometries or flexible materials.
✔ No Part Damage
Since there’s no physical contact with the component, there’s zero risk of scratching or deformation, particularly important for delicate or soft materials.
✔ Inline and Shopfloor Integration
VICIVISION’s optical measurement machines are designed to be used directly on the shopfloor, enabling real-time quality control and reducing bottlenecks between production and inspection.
✔ Enhanced Data and Reporting
Non-contact systems often include powerful metrology software for automatic measurement, pass/fail reporting and SPC (Statistical Process Control), making it easier to identify trends and improve quality processes.
