Cylindrical ring gages have a number of inspection purposes. They are used as Go/No-Go gages to inspect the outside diameter of a shaft or rod. They are masters for dial bore gages, internal micrometers and coordinate measuring machines (CMMs). 

Starrett is offering a comprehensive white paper that discusses why traditional approaches to measurement data collection are inefficient and error-prone without the ability to support IoT/ Industry 4.0. 

In my last column I listed some basic equipment requirements for the calibration of thread plug gages so I thought it would be helpful to give mating gages the same treatment. 

Data collection has historically been completed manually. Before wireless gaging came onto the scene, staff would write down and physically log output data, a slow process with plenty of room for error.
