Procedures
Each of the procedures below contain graphics that can be customized with easy to use dialog tabs. When your analysis is complete, use the Report Writer to create custom output in a
format compatible with major word processors, rich text
and HTML.

Bias
To determine gage bias, a reference standard with a known
value is necessary. Measure the part on the gage being tested
a minimum of 10 times, and preferably more than 30 times.
The greater the number of measurements, the greater the
accuracy. In virtually every case, there will be bias, however,
the bias may not be statistically significant. The significance
is tested using the t-distribution, and increasing the number
of measurements increases the discriminatory power of the
t-test.Input the measured values into the Gage Bias spreadsheet
along with the reference value and the process variance and
process tolerance if desired, click the Compute Bias button,
and the biasstudy is complete. Click the print icon, and the
results appear in the Report Writer. Right-click on the graph,
and a tabbed dialog box appears that allows you to customize
the graph.

Linearity
To determine linearity, several trials must be made with several
standards. The standards must span the operating range of the
gage. To analyze the data, select Procedures than Linearity from
the menu. The Linearity screen is shown below with sample data.

Repeatability & Reproducibility
Select "Procedures" then“Repeatability & Reproducibility”
from the menu and enter your data. An example Repeatability
&Reproducibility screen is shown below. In the “Method” frame,
the “ANOVA Method” or the “Range & Average Method” can be
selected for analysis. The ANOVA method is used as the default because it is more accurate. In the“Based On”frame, the analysis can be conducted using the process variation or the process tolerance; process variation is the default. The default output is the
99%R&R index. The level of the index can be changed from 99%
to anydesired level using the“Index Level”box on the toolbar.

Design a Gage Capability Study
To design an R&R study select Procedures then Design R&R
Study from the menu, and the following screen will appear.
