Improving Measurement Precision of Enclosure Parts by Using Separating Techniques

摘要

A roundness error measurement system has been constructed for the nuclear fuel element enclosures, in which three ultrasonic displacement translators are attached on a rotating hollow spindle .The enclosures driven by feed units pass through the hollow spindle when the enclosure is measured. The measure accuracy of enclosure parts has been improved and the cost has been reduced by using the error separating technique.
