Metrology 4.0 - A Collaboration Driving Roundness Metrology Forward

Digital Surf and Taylor Hobson, world leader in surface and form metrology, have a common history dating back almost 30 years. The two companies recently completed a new round of co-developments resulting in the release of an updated version of Metrology 4.0 software with the manufacturer’s brand new Talyrond 500 PRO, a powerful instrument for roundness metrology.

What Is Metrology 4.0 Software?
Metrology 4.0 software made its debut in 2018 with the Form Talysurf PGI NOVUS series of surface instruments. Following recent co-developments with Digital Surf, the software now also allows both measurement and analysis on the Taylor Hobson roundness instrument series.

Mountains platform software features are seamlessly integrated into Metrology 4.0, which allows better control of the measurement process and the direct creation and export of analysis documents.

This full integration offers several clear advantages. Users working with roundness can now benefit from a fluidified and optimized workflow, with the ability to progress from measurement to reporting within the same interface, making the metrology process much simpler and more straightforward. This is particularly useful in a production context (shop floor use).

Bringing Together The Experience Of Instrument & Software Experts
“Cooperation between Digital Surf and Taylor Hobson goes back almost 30 years” said François Blateyron, director of research & metrology at Digital Surf. “Both teams understand each other. Our development department was able to build on its robust scientific knowledge to adapt to the new challenges of roundness metrology in the context of this project.”

“Our combined experience in the field of precision roundness measurement and in-depth analysis software provides unique benefits.” said Jon Gardiner, senior business development manager at Taylor Hobson. “Together we have produced the seamless integration of mechanical hardware and roundness metrology analysis software to deliver a world-class measurement instrument.”
