5.7.1 About “AMF Index”
AMF Index 1
INDEX 1 (Total) --- CPK (Process Capability)
It indicates if the value obtained by the formula below meets the upper limit standard value (USL).
“Deviation with single head at a single angle (3σ) + “Average distance from the center (
)”
Figure 67
AMF Index 2
It quantifies the variation of mounting position at a single angle against the variations of all the four
angles (0, 90,180 and 270 degrees).
If it falls below 1.0, feeding back the correctio values is effective.

[VgChart] .
The chart window is automatically created.
Figure 69
2. Check the mounting state for each head on the chart window.
Figure 70
<When the “AMF index 1” value falls below 1.0>
Check the chart window to determine which head is the causal factor that the “AMF Index 1” does
not meet the specification.
Analyze the chart and perform the further adjustment if needed.
* See “How to analyze the “VgChart”” for how to interpret the graphs.
* See “11.Basic adjustments required when “AMF index 1” falls below 1.000” for the adjustment
procedure.
