optical dimensional microscope image vs 3d data in omnisurf3D

Don’t be fooled by your measuring microscope!

Have you ever used an optical microscope to look at dimensional features? It’s a fairly common task to look at lateral features such as circumferences on relatively flat components like plates, panels, and even circuit boards.Many measuring microscopes (or “optical dimensional microscopes”) also incorporate some method of optically measuring heights—and thus many systems report numbers

measurement instrument performance testing

Instrument performance testing

Here’s a common challenge: your vendors and/or customers are using different equipment to verify part quality…and their results conflict. How can you determine which system is “correct?”Here’s another common issue: you have a new measurement requirement, but you’re not sure which instrument can do the job best. Vendors give you specs, and even demos, but

What’s beyond average roughness?

In surface texture, Average Roughness (Ra) is still the most widely used parameter, even though it has serious limitations. But what other tools are there that can tell us more about our surfaces? We’ll be exploring that topic in a series of posts, so watch this spot for updates every week!Looking for more info? Check

wear scar on a spherical surface, measure wear depth, measure wear volume

Wear Analysis

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 your most complex underlying geometries.

Surface Texture: meet the Scouts!

If you’re reading this blog, you know that we love sharing what we know about surfaces. Sometimes that information impacts people’s lives in the most unexpected of places!Brian Vogel is a Scout troop leader, in addition to his 30-year career in drafting and metrology. Though he’s amassed a wealth of GD&T and surface texture experience

surface texture measurement, marbles measured with creaform metrablack 3d scanner, brian vogel, analogy for micro surface texture measurement

Losing our marbles?

Here’s a fun “macro” example of an important aspect of micro surface texture.Peak curvature is a measure of the “sharpness” of the small peaks in a surface. Many papers have been written on this important tribology parameter because it relates directly to a number of surface functions. But if you’re trying to estimate peak curvature

Training Beyond School: Carl Musolff’s career as metallurgist, metrologist, and mentor

Engineers often wish there was a particular expert in the room to help them navigate the journey from problem to solution. For some very fortunate engineers, Carl Musolff has been that expert.Carl Musolff has made a career of solving challenging problems, for engines of every shape and kind. But what he really loves is sharing

A power boost for your measurement system

Most measurement systems ship with software for acquiring data and displaying it in generalized ways. But what if you need to calculate special parameters, or display data in a way that’s unique to your process or application?   Custom software tools, or “helper applications,” can pick up where off-the-shelf instrument software leaves off, filling in features

surface texture of rollerball pens measured with a GelSight tactile gage

What am I missing when I only measure average roughness?

Here are 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 grips feel great to hold. Speaking of “feeling great,” we put the pen grips under the
