A collection of stones can be a good “macro” analogy for micro texture. The dataset was created with a 3D scanner. As with the marbles in this dataset, a 3D measurement tends to capture the full dimensions of each rock in the field of view, while a 2D slice through the data will likely miss … Read more
A bowl of marbles is a good “macro” analogy for micro texture. The dataset was created with a 3D scanner. In the 3D measurement data, we can see enough of most of the marbles to estimate their radii (try it with a circular mask in OmniSurf3D). If you cut a 2D slice through the data, … Read more
We recently acquired three model “LM6708” tapered roller bearing assemblies from different manufacturers. We decided to have a look at how their surfaces compared, and differed, right out of the box. This dataset is the Timken bearing, which has a micro-finished, crosshatched surface. Setting the vertical scales equal to each other makes it easier to … Read more
We recently acquired three model “LM6708” tapered roller bearing assemblies from different manufacturers. We decided to have a look at how their surfaces compared, and differed, right out of the box. This dataset is the National bearing, which has a ground surface. Setting the vertical scales equal to each other makes it easier to compare … Read more
We recently acquired three model “LM6708” tapered roller bearing assemblies from different manufacturers. We decided to have a look at how their surfaces compared, and differed, right out of the box. This dataset is the FKG bearing, which has a ground surface and several taller/deeper features. Setting the vertical scales equal to each other makes … Read more
We compared the surfaces of the grips on two of our favorite pens: the “Uniball Grip” that we use with our logo, and the Pilot G-7 that we use for the Notepad Series. Both are relatively inexpensive, but they both write very well, and both feel great to hold. We put both surfaces under … Read more
