Back to Basics: How Air Gaging Works

Air gaging technology is continually improving as computer technology continues to evolve.  These systems can range from simple desktop readouts to full SPC computers with contour scanning capabilities.  As manufacturing requirements continue to become more complex, air gaging technology evolves to meet the demand.  For these reasons, air gaging will remain a viable measuring solution for generations to come.
Air gaging technology has its roots back over 70 years and is today a viable and highly reliable method for many applications in industries where a high volume of parts is produced or where the precision of hard-to-access dimensions makes other measuring techniques impossible.

Direct Load Position Sensing with Secondary Feedback Encoders

An adjustable cylinder honing tool in operation. By comparing the indicated positions of rotary and linear encoders to one another, the motion control system can monitor mechanical drive wear and tear over time. As the drive begins to exhibit increasing play and slop, the amount
of deviation between the two readings will increase and provide valuable information for preventive maintenance and predictive failure. (Photo courtesy of Fraunhofer)
To help verify machine tool accuracy in closed-loop motion control systems, direct load monitoring using secondary feedback encoders eliminates common sources of position error — mechanical backlash, non-linearity, and hysteresis — and saves money along the way.

As The World Turns

Robot places a machined bearing into the Equator’s measuring envelope (foreground), with part conveyor and Okuma twin-spindle lathe in background. Aluminum block on Equator’s fixture plate has hole in center which Equator uses to set its coordinate system. Part is placed in center of block for measurement.
A process-controlled hard turning cell in this Texas machine shop deploys programmable gages for measuring and sorting mud-motor bearings – and the cell pays for itself in 18 days.

Hard Gaging Goes Soft

Equator measurement results are presented as variable data so the machinist can compare the current part with recent measurements, rather than get a simple pass/fail result.
Jet engine component maker Meyer Tool reduces its hard gage costs by replacing multiple costly hard gages with a single software-driven Equator gage from Renishaw.
