Curved Profile Tool in OmniSurf3D

Sometimes roughness matters along a curved path — but a stylus can’t measure along a curve. What can you do? A new tool in OmniSurf3D lets you construct a curved path over your data and analyze the profile along that curve. Find out more in this Surface Matters blog post.

GAR Strip: New additions to the Surface Library

This week we made a big addition to the our Surface Library of 3D surface texture datasets! The new Microfinish Comparator series includes high resolution, 3D data of the 22 surface texture samples on a GAR S-22 microfinish comparator gage. These textures represent various machining operations and surface roughness amplitudes. These samples make it easy to compare and explore these common surfaces in great detail.

How to Remove Shape from a Complex Surface

Sometimes in surface texture analysis we need to measure difficult shapes, such as those resulting from a local process or local damage. Large features or distorted underlying geometry can further complicated the process. In this case study, we show the step-by-step process in OmniSurf3D for taming a challenging surface analysis task.

Notepad Series Video: Why Not Repeatability?

How good is my surface roughness gage? In this Notepad Series video we look at why repeatability is not a good judge of a stylus instrument's condition or capability. In fact, good repeatability may indicate a bad instrument!

Solutions Showcase: NozzleView Software

Digital Metrology regularly works with metrology instrument providers and their end users to solve tough problems. This recent project is a great example. Digital Metrology developed the NozzleView software to better understand the geometry within fuel injector spray holes. These geometries are critical to fuel injector performance, but until recently they have been very difficult to measure and analyze. The NozzleView software lets users to analyze and explore the shape of each spray hole throughout its length, and to visually interact with the data to gain a better view, and better understanding, of the surface geometries.

Notepad Series Video: Peaks, Valleys and Skewness

The surface heights of many machined surfaces form a normal distribution with a common bell shape. But often we want a surface that is skewed toward the peaks or valleys. The Rsk parameter is widely used to report the direction and degree of skewness...but Rsk has some very serious issues baked into the math which can lead to incorrect conclusions. 

In this video we examine the Rsk parameter, how it is calculated, and how the calculation can lead to instability. We also provide some alternative parameters that are more stable for production measurement.

Engine performance? It’s in the surface texture.

There’s information about your performance and machining processes hiding in your surface texture. But you need to be able to see it to improve it. We sat down with Brad, the larger-than-life personality who fuels QMP, to talk about how he and QMP mine surface texture for every ounce of performance from their engines.
