What is the importance of repeatability in alignment measurements?

Repeatability in alignment measurements is crucial because it ensures that the results obtained during the alignment process are consistent and reliable. When measurements can be repeated with similar outcomes, it indicates that the alignment setup is stable and that any adjustments made are effective. This is particularly important in precision alignment tasks, where small discrepancies can lead to significant operational issues, such as increased wear on machinery or misalignment during operation.

If repeatability is established, it allows technicians to trust the accuracy of their alignment work, leading to fewer mistakes and reducing the likelihood of needing to redo alignments. The ability to consistently get the same results also aids in correlating measurements over time, facilitating preventive maintenance strategies and helping to predict when alignments might be needed again. Thus, consistent and reliable metrics established through repeatability play a fundamental role in ensuring machine performance and longevity.
