Ins and Outs of ID/OD Comparative Gaging

From Mahr Federal Inc.

Circles are the most frequently produced machined form. Generated by many different processes- including turning, milling, centerless grinding, boring, reaming and drilling- there are, correspondingly, a wide variety of gaging methods used to measure inside and outside diameters. At the low end, a hole could be measured with a scale or a fixed go/no-go gage.
