Opening an Image File in OmniSurf3D

You likely are aware that you can drag and drop your data into OmniSurf, OmniSurf3D, and OmniRound to open it. It is a convenient way to access your data without needing to open it from the file menu. Did you know that you can also do the same with an image file? Here is an

Read our “Hidden Waviness” Article in Quality Magazine

Our new article, “Hidden Waviness: When measuring roughness cannot solve quality challenges,” appears in the June 2020 issue of Quality Magazine. This article was written in conjunction with Don Cohen of Michigan Metrology. Specifications for surface texture frequently focus on surface “roughness”—the finer structures in the texture—often to the exclusion of the “waviness”—the larger structure

Digital Metrology comparing size of 3D areal surface texture measurement

How big is that 3D dataset?

When we look at an areal (3D) measurement of a surface it can appear as a vast landscape of many sizable features: An optical, areal measurement typically includes millions of points.  On the other hand, a stylus-based, 2-dimensional measurement typically includes just thousands of points.  But just how big are the areas covered by these

How much does it cost to compare measurement systems? The answer: one cent.

Optical measurement of surface texture is becoming more and more widespread, and new technologies are providing faster measurement of larger areas. However, in the quest to measure faster over larger areas, we sometime lose touch with the ability to resolve smaller features. Most of the time there are hints at performance in the measuring system’s

Interactive Bandpass Filtering

Many surfaces are dominated by a repeating, pattern or shape in their texture. Sometimes this texture is desired, as on a gripping surface. Other times it is something we try to avoid, such as “orange peel” in paint, or chatter in a bearing raceway. In each of these cases it is helpful to isolate the

Can a Stylus Really Measure This Surface?

For many critical applications, companies are finding it necessary to not just assess the geometric aspects of the surface, but also the quality of the surface. You’ll find specifications with terms such as “torn and folded material,” “porosity,” “pull-outs,” “micro-burrs” and “micro-ledges.” The surface in the image above is marked by torn and folded material
