Use My Shoulder for Support
Building a shoulder stop into an air snap gage takes away operator influence and boosts measurement accuracy.

Does Repeatability Outweigh Accuracy?
Both of these gage characteristics are important, but sometimes repeatability can compensate for a certain degree of inaccuracy.

The Need for Speed
In high-volume production, cost-effective gaging depends on how fast you make measurements and interpret the results. Here’s one approach that might meet the needs of your operation.

Considering Probes for Roughness Measurement
Skidded probes are available in two types: longitudinal and lateral. Here’s how to decide which is best for your surface finish measurement.

In a perfect world, there would be just one international standard.
Read MoreShould You Gage to Part or Part to Gage?
There are many questions to ask when deciding what gage to choose for an application, but whether to bring the gage to the part or the part to the gage is one of the most fundamental. And the decision is influenced by a host of factors.
Read MoreThe Dirt on Gaging—It’s All Around
The common gage is always in contact with dirt. Accurate air gaging requires proper tooling maintenance and air supply vigilance.
Read MoreLosing Accuracy One Micron at a Time
Most gages on the shop floor provide a specified level of accuracy in conditions for which they were designed. However, it’s critical to think about gaging requirements before putting instruments in tight-tolerance production environments, and possibly having them not meet expectations.
Read MoreTwo Cases of Gage-Improvement Failure
The call is a common one: When tolerances are tight, better gages are needed to improve the measurement process. However, what might seem like a simple fix can sometimes lead to unforeseen issues.

The Case for the Perpendicular Indicator
In most cases, a standard or dial indicator is adequate for gaging requirements. However, sometimes the normal orientation of a standard indicator does not work for a particular application. In this situation, a perpendicular indicator might be the better choice.
