Surface texture analysis - golf club golf ball interface

Customer Spotlight: PING golf equipment

Any golfer knows the satisfaction of watching a well-hit drive soaring for hundreds of yards, right down the center of the fairway. In golf, the 500 micro-seconds of contact between the club face and ball are the difference between a successful shot—and a walk in the weeds. It’s no wonder that golf equipment manufacturers are

Digital Metrology - Quality Magazine article -Y14.5-2018 Section 4.1 (s) rule causes conflict in Geometric Dimensioning and Tolerancing (GD and T)

GD&T’s New Rule and What it Means for Measurement

In a new article in Quality Magazine AJ Mennuti and Mark Malburg discuss the challenges associated with  the release of ASME Y14.5-2018 and its new fundamental rule “s.” Rule “s” specifies that the evaluation of GD&T features includes every aspect of a surface’s texture and flaws. When measuring straightness, say, one must include the roughness,

Surface Metrology with a Smart Phone?

The iPhone 12 Pro includes LIDAR technology, primarily to improve the speed and accuracy of the camera’s focus. But you can also use it to map the shapes and sizes of objects. App developers are in the beginning stages of some amazing work to take advantage of this technology. But OmniSurf3D is already there…

Image Rotation and Animation with OmniSurf3D

When it comes to understanding surface texture, one of the most powerful tools we have is an interactive visual of the surface. A 3D surface texture measurement tells a great deal about a surface, such as how features relate to each other—information that can only be hinted at by 2D measurements. 3D measurements help you

Measuring gear tooth waviness to control gear noise - Digital Metrology

Measuring gear tooth waviness

Gear tooth waviness is a hot topic these days. As automobile engines have grown quieter, other noise sources, such as gears, are getting much more attention. We know that mid-wavelength waviness (two to three peaks per gear tooth) correlates to gear noise. What we have been lacking, however, are parameters that correlate to that noise,

Surface texture analysis, remote analysis - Digital Metrology

Surface analysis when working remotely

When you send parts to a measurement lab, you likely receive back a PDF file with some parameter values, and maybe a part profile. That’s probably just enough information for you to show whether the parts meet spec. But you aren’t likely to get any real sense of how that surface looks, feels, or performs.
