Measurement system analysis of Gauges

Method shows problems with:• Repeatability

• Reproducibility

• Part-to-part variation

2017-09-01 4

Go/No Go • MS noise <9%

• MS noise <30% of tolerance width

Process optimization• MS noise <4%

• MS noise <20% of tolerance width

Reference: Z. Barsoum; J Samuelsson, Lightweight Optimised Welded Structures (LOST), 2009.

Gauge contributed with 58% of the total variation
