In precision manufacturing, the demand for accurate, repeatable and efficient inspection methods continues to grow, especially when dealing with small or intricately shaped components. Traditional contact-based measurement methods often fall short when inspecting delicate features, tight tolerances or micro-scale geometries.
That’s where optical measuring machines come into their own.
In this article, we explore why optical metrology is the ideal solution for inspecting small and complex parts, and how VICIVISION UK is supporting British manufacturers with cutting-edge non-contact measurement systems designed specifically for turned and cylindrical components.
Why Small and Complex Parts Require Specialised Measurement
As manufacturing technologies evolve, so too does the complexity of components. From miniature medical implants and precision gears to aerospace fasteners and hydraulic fittings, manufacturers today are producing parts with challenging geometries that must meet strict tolerance requirements.
However, inspecting these parts accurately and efficiently poses several challenges:
Limited accessibility for traditional probes and contact-based tools
Risk of damage due to physical contact with delicate surfaces
Variations in operator handling, leading to inconsistent results
Long inspection times that impact throughput and productivity
This is why more manufacturers are turning to optical measurement systems that use light, lenses and advanced software to deliver fast, high-precision, non-contact part measurement.
What is an Optical Measuring Machine?
An optical measuring machine is a non-contact inspection device that uses high-resolution cameras, lighting systems and telecentric lenses to capture detailed measurements of a component’s geometry. These systems convert images into precise dimensional data, allowing manufacturers to inspect parts with speed and consistency.
VICIVISION’s optical machines are purpose-built for measuring turned and cylindrical parts, capturing hundreds of dimensions in a matter of seconds, all without touching the part.
The Benefits of Optical Measurement for Small and Complex Parts
High Precision at Micro Scale
VICIVISION systems use advanced optics and digital image processing to achieve micron-level accuracy. This level of precision is especially beneficial for measuring features such as small chamfers, radii, threads, and grooves where traditional gauges or CMMs struggle.
Non-Contact and Damage-Free
For small or delicate parts, even light pressure from a contact probe can cause deformation. Optical machines eliminate this risk, ensuring the integrity of every component is maintained during inspection.
Fast, Automated Measurements
Time is money in modern manufacturing. Optical measurement systems reduce inspection times from minutes to seconds, freeing up operator capacity and reducing bottlenecks in production.
Repeatability and Consistency
Manual inspection methods are often subject to variation between operators. VICIVISION systems deliver consistent, repeatable results, regardless of who is operating the machine, essential for meeting ISO and IATF compliance requirements.
Compact and Shopfloor Ready
Designed for use directly on the shopfloor, VICIVISION machines allow operators to perform fast checks right next to CNC lathes and production cells. This enables immediate process adjustments and supports real-time quality control.
Industry Applications: Where Small Part Measurement Matters
Optical measurement of small and complex parts is essential in a variety of high-value sectors:
Medical and dental – implants, prosthetics and surgical components
Automotive – injector nozzles, turbocharger parts, connectors
Aerospace – lightweight fasteners, small diameter shafts, fittings
Hydraulics and pneumatics – seals, bushings and turned bodies
Subcontract engineering – multi-industry applications and quick turnarounds
For all these industries, VICIVISION machines offer unmatched speed, accuracy and reliability when it comes to turned part measurement.
