High Precision Metrology Instruments for Multi-Part Measurement

One of the primary challenges of manufacturing high precision parts on a large industrial scale is ensuring uniformity within, and across, product batches. Minor deviations in roundness, roughness, contours, and overall form can render precision components unusable for their design intent. Metrological assessments of precision components like bearings, fuel injectors, lens molds, and more, are subsequently a vital part of the quality control and product validation stages of manufacturing. However, conventional metrology instruments struggle to meet the high volume and high throughput requirements of high precision engineering.

Taylor Hobson has extensive experience working with manufacturers of precision components with high volume product outputs, where measurement inaccuracies and production errors can have significant cost ramifications. However, measuring individual components and extrapolating data to determine respective batch quality is both time-consuming and ineffective.

Instead, we have developed metrology instruments with a multi-part measurement technique that enables the simultaneous inspection of over thirty parts without operator intervention. This technique utilizes the Talyrond® 500HS; the world-leading metrology instrument for fast and reliable roundness measurements.

How does Multi-Part Measurements work using Talyrond 500HS

The rotary stage attachment for the Talyrond® 500HS is a bespoke fixture comprising a tailored carousel and a socket that connects directly into the V grooves of the Talyrond® 500HS. This augments our singular metrology instrument to facilitate a multi-part measurement system specialized for roundness measurements of distinct parts.

In a test environment, this metrology instrument was used to measure twenty samples, twenty times. The results gave an extremely low standard deviation of below 10 nanometers (nm), with an average spread of 20.6 nm. These measurements demand no additional software, running through the metrology instrument’s standard array. They are fully automated and offer exceptional levels of throughput that significantly exceeds traditional metrology instruments.

Metrology Instruments from Taylor Hobson

Taylor Hobson has a rich history in the development of metrology instruments for manufacturing high precision components on industrial scales. We have pioneered the next generation of profilers for measuring surface form, metrology, and roughness to guarantee outstanding batch uniformity in tough working environments. Assess the surface properties of automotive components, dental prostheses, medical devices, and more, with Taylor Hobson’s metrology solutions.

If you have any questions about our metrology instruments, please do not hesitate to contact us directly. Surface profilers are used to measure and characterize the surface features of a material on the micro- and nanoscale. These minute topographical features are typically categorized as roughness, waviness, or directional lay, representing potentially microscopic structure superimposed on the true form of a material’s substrate.
