Open publisher page 1 citations

Abstract

A gage is being developed to make precision measurements of moving surfaces in a manufacturing environment. A prototype has demonstrated submicron repeatability and accuracy at the 2- to 6-micron level as well as the ability to measure parts moving at about 1 in./min. The system is described, and the means to make the accuracy comparable to the repeatability and to increase part velocity to more than 200 in./min are indicated.
