Abstract

This project, sponsored by Hexagon, aims to develop an efficient way to determine defects along the granite dovetails of their Coordinate Measurement Machines (CMMs). The key aspect of the project is to detect any variations in the surface flatness of the dovetails that are larger than two to three microns in height. Developments were made in researching laser interferometry; however, the presence of a crown on the dovetail led to the development of a Go-No Go gauge which uses air bearings to make detections. Mathematical analysis finds that, when the prototype gauge is supplied with about three to four pounds per square inch of pressure, that the gauge will be able to catch these defects.
