Do you really know the difference between roughness and waviness?

If we want to understand and describe surface texture, we need to understand how to separate roughness from waviness. We often do this by applying a Gaussian filter. In this short video we show you how that process works. We'll also show you the importance of the "filter cutoff wavelength," where we choose to separate roughness from waviness. This cutoff has a huge impact on the values of our surface roughness parameters!

Measuring microscopes (or “optical dimensional microscopes”) can be used to measure lateral features like circumferences. Some also report 3D surface roughness statistics...but there's a big difference between optical dimensional measurement and optical surface texture measurement. OmniSurf3D software can help you to verify that the measured feature heights are "real" — see how in this Surface Notes blog post.   Read More

Analyzing wear depth is not something you’d usually think of as “fun”…but with the Wear Analysis in OmniSurf3D, it kind of is! In this video we use the Wear Analysis tool to quickly measure the depth and volume of a wear scar. The whole process is super-fast and really intuitive.

You have a worn component...but worn by how much? Or, perhaps you have several parts that have worn differently, and you need to know why. 

The new Wear Analysis tool in OmniSurf3D lets you see the wear and describe it numerically, in just a few clicks. It can even handle complex underlying geometries. 

See it in action in this video!

What do you do when your measurements don’t match what your supplier or customer measured?  In this Notepad Series video we show you a technique that can help you compare the measurements—not just the differences in the average values but also the variability in the measurements. It’s very helpful for interpreting differences in data.
