MSA (Measurement System Analysis)
Measurement System Analysis
Study of the variation and suitability of a measurement system before using its data for decisions.
Examples
- 01Before using a new vision system, the team runs an MSA with 10 parts, 3 operators and 3 repeats.
- 02The supplier's MSA shows a gauge R&R of 35 %, so its capability data cannot yet be trusted.
- 03When MSA shows the gauge cannot separate good and bad parts, the measurement method is redesigned.
