Mahr Inc., a subsidiary of the Mahr Group, has over 160 years of experience providing dimensional measurement solutions to fit customer application needs.

Consolidation is something we’ve all done. It’s efficient and can help save time and space and naturally leads to greater organization and productivity.

Here’s a thought: what if you could also perform multiple measuring tasks at the same time, on the same part with one machine, right there on the factory floor?

In this article, I wanted to go beyond the simple go/no go measurements that most air gaging is used for. Air gaging is a highly effective and efficient way for measuring these simple diameter requirements. It is also extremely repeatable on tight tolerances, but for this article, I wanted to focus on using air gaging to measure form requirements such as roundness, flatness, perpendicularity/squareness, taper, straightness, matching, and others. 

While electric vehicles (EV) aren’t new, they are gaining traction and popularity across the globe.

As related to form metrology, a roundness measurement defines how closely the shape of a part approaches that of a perfect circle. 

Form is a relatively easy thing to measure in many senses. In the simplest manner, form measurement involves a probe or stylus being moved along an ideal circular or linear path to gather data on the probe movements relative to that ideal geometry.

Camcraft Inc., located in Hanover Park, IL, manufactures high-precision components and assemblies. Utilizing the latest machining technology and automation, Camcraft manufactures the most complex hydraulic engine management and fuel system components for on- and off-highway applications.

It is generally agreed that engineering is about tradeoffs, and that has always been particularly true in regard to measurement machines. There are several types of measurement, and higher performance in one area generally meant less capability, or none, in other areas. 

A friend of mine likes to quip that someday computers will make all our lives easier. He’s kidding (I think), but it seems to be a fact of modern life that every time we open our phones, tablets, or computers, or even check our watches, there are upgrades waiting to be installed for the apps we have, and new and improved apps on offer to replace those.
