Get Ready for the Microinch Revolution
Many of us remember when the typical tolerance for machined parts shifted from thousandths to “tenths,” and we had to adjust both our production techniques and our QC measurement methods. As ever more technical products make the need for precision even more profound, a similar shift is now under way, toward millionth-measurements. This time, our gaging methods will have to change radically.
Previously, we focused much of our attention on the gage itself: as long as the instrument was designed to the required degree of accuracy and maintained properly, we could usually get by, even at the “tenths” level. Now that we’re trying to measure tolerances of 50, 30, or even 20 millionths, we must shift our focus to the measurement process and the environment in which it takes place. Where temperature and cleanliness were formerly somewhat abstract issues, they now become essential concerns.
