2. The absence of variation amongst multiple measurements taken under the same conditions.
3. The degree to which a machine can move its parts to the same position (location) repeatedly, which is closely (and mathematically) related to its precision and accuracy.<!--Repeatability in this sense is broadly synonymous with [[precision]], but machine tool builders sometimes differentiate them with two closely related [[operational definition]]s.-->
