Three types of data (Front, Rear, Front and Rear Total) are shown in the precision data.
The reason that the X-axis Cpk value of Front and Rear Total drops slightly even though the value
of each side (front and rear) is appropriate is that there is a large difference between the maximum
and the minimum of the rear X-axis (Ideal difference: 0). (Opposite sign) See the graphs below:

0.015-0.027＝-0.012
Enter -0.012 into the rear X-axis mounting position offset so that the Cpk will become similar
to the dotted line on Graph (1) (Correction target).
For the Y-axis: Although the graph is shifted to the negative side by 0.010 (fug40-3(2)), the FY
and the RY are so balanced that the Cpk does not drop.
It is recommended that the front offset be 0 (*); enter the rear offset only.
If the average exceeds 0.005, carry out Adjustment Step 39. In this case, enter an offset.
* Enter "0" into the front offset and adjust with the rear offset so that the Cpk will become the target value.

Maintenance Adjustment Light Transfer-Head Assembly (8 nozzles)
Remarks
Press [Pickup position].
Select the stage to be taught.
Check that:
"XY" and "Z" are selected
(highlighted).
Check that "Check Posi L
table" is selected.
If "Check Posi R table" is
selected, press that key to
change "R" to "L."
Press [Unlock] and [Jig setting] simultaneously.
Place the jig at Position 2
of the feeder table of the
selected stage.
Fit Nozzle 120 or 130 onto
Nozzle position 3.
Press [Unlock] and [Pick pos teach] simultaneously.
The head moves over to the jig.
The head camera recognizes the hole on
the jig so that X and Y of the pickup
position are recognized and corrected.
Nozzle 3 descends to the jig so that Z of
the pickup position is determined.
