Optical roughness measurement according to international standards

Measurement of roughness, form and waviness

Quantitative analysis according to international standards

In manufacturing processes, surface finish quality of incoming materials directly affects the quality of the end product. Quantifying surface roughness using accepted and traceable international standards such as ISO 25178 and ISO 4287, is critical to ensuring excellent vendor-customer relationships. NanoFocus’ 3D surface metrology systems provide users with the repeatable and reproducible roghness measurements necessary to quantify surface compliant with internationally standardized parameters. 

Roughness measurements with profile accuracy even in production

Roughness measurements with the confocal µsurf technology developed by NanoFocus show a 99% correlation with tactile measurements (study by the National Institute of Standards and Technology (NIST), USA). This means that the deployment of the NanoFocus roughness measurement technology is not in conflict with tactile measured results, so historical measurement data or parameters deliverd by suppliers that use tactile methods are comparable without any problems. However, the NanoFocus optical 3D metrology is able to quantify surface roughness faster, more comprehensive and with higher accuracy. On these grounds, the optical roughness measurement offers many advantages compared to the tactile roughness measurement, especially in production control.

Roughness measurements with NanoFocus metrology systems are non-contact. That is why sensitive, soft or flexible surfaces can be measured accurately as well without any damages. Within seconds, roughness measurements are completed and can be analyzed according to numerous 2D and 3D parameters. The high resolution and the excellent repeatability of the confocal NanoFocus surface measurement systems enable reliable roughness measurements and guarantee the proper compliance with the product quality standards. Additionally, the NanoFocus metrology systems were developed for the industrial application and due to their robust setup, the confocal microscopes can also handle rough production environments. This base also allows the construction of compact surface measurement systems for portable roughness measurements such as the µsurf mobile .

Roughness measurement in R&D

In automotive industry, the quality of key functional parts such as camshafts is of great importance. Already in their development stages, components are put through exact surface examinations. With the µsurf technology, surface roughness is determined down to the low nanometer ranges with the required precision. With these analyses, you assure the proper functionality of your components before they go into serial manufacturing.

Roughness measurement in process control

The honing process of engine cylinders is crucial to ist functionality and Efficiency. With the NanoFocus µsurf cylinder, the honing structures of the cylinder walls can be inspected contact-free to adjust the manufacturing process. The durability of tools can be optimized and downtimes are projectable much better. Details 

Roughness measurement in quality control

Dental implants need an especially roughened surface for an optimal healing process. The NanoFocus µsurf Technology enables the automated 3D measurement of dental implants and the evaluation of roughness and height parameters compliant with ISO standards. Details
