Radial deviation gauge D. J. Whitehouse

Abstract

Preferred commercial methods of measuring the out-of-roundness of a
workpiece are based upon radial methods. These incorporate a very accurate
spindle either to carry the transducer or via a table to the workpiece.
Consequently they are best operated in a controlled environment such as in an
inspection room. However, there is a requirement for measuring the workpiece
near to the machine. This paper describes one possibility both in theory and
practice.
