A Review of Diameter Measurement and a Proposal for the Improvement Thereof

In order to establish traceability of area of pressure measurement, piston–cylinder assemblies are characterized dimensionally. Piston, cylinder and master ring gauges demand diameter measurement uncertainty of about 30 nm. As focused efforts to achieve the requisite uncertainty, most of the trendy diameter measuring machines, used and available across the globe, are studied for their designs and performance. Conceptually, the uncompensated systematic error contributes significantly to the uncertainty of the measurements. In order to understand the magnitudes of the various errors, some of the key comparison reports are also studied. Based on the analysis of the review, laser-based displacement interferometer measurement systems are proposed. Theoretically, the proposed models reduce the Abbe’s error.
