Gage Analysis, also known as Measurement Systems Analysis,
allows you to determine that your Measurement System is capable of consistently
measuring the process. This is a critical requirement for Statistical
Process Control, as well as for determining whether a specific product
or service meets customer's needs.
Our SPC-PC IV Gage Analysis meets the latest
AIAG (Automotive Industry Action Group) guidelines for Gage Analysis.
Control Charts are provided for each analysis, which also aids in troubleshooting.
(See also Repeatability
Analysis)
SPC-PC IV offers the following methods for
Gage Analysis:
- Gage Repeatability &
Reproducibility
 :
Gage Reproducibility, also known as Appraiser Variation, isolates the
Operator-to-Operator differences. Repeatability determines the Equipment
Variation.
- Gage Bias (Accuracy):
The difference between the average value observed using the
test gage and the 'true' value.
- Gage Linearity:
A measure of whether the gage bias is the same over its operating
range. For example, does it have the same error for small parts as for
large parts?
- Gage Stability:
A measure of the bias over time. Stability can be the best
method for determining Calibration intervals.
