If there is a table whose average is 0.005 or more
correct the mounting position following the procedures below:
Precision data offset
Average of X-axis values……Xave
Average of Y-axis values……Yave
Mounting position offset
X(mm) value ……… Xos
Y(mm) value ………Yos
From the preset mounting position offset ([Preset Xos]
[Preset Yos]) and the average of precision data ([Xave, Yave]),
mounting position offsets to be set ([New Xos][New Yos]) are
calculated as follows:
Enter the mounting position offset ([New Xos][New Yos]).
Then follow Steps 25 to 31and check the precision data.
Right front reference
[New Xos]＝[Preset Xos]＋Xave [New Xos]＝[Preset Xos]－Xave
[New Yos]＝[Preset Yos]－Yave [New Yos]＝[Preset Yos]＋Yave
Left front reference
[New Xos]＝[Preset Xos]－Xave [New Xos]＝[Preset Xos]＋Xave
[New Yos]＝[Preset Yos]－Yave [New Yos]＝[Preset Yos]＋Yave
Right inner-side reference
[New Xos]＝[Preset Xos]＋Xave [New Xos]＝[Preset Xos]－Xave
[New Yos]＝[Preset Yos]＋Yave [New Yos]＝[Preset Yos]－Yave
Left inner-side reference
[New Xos]＝[Preset Xos]－Xave [New Xos]＝[Preset Xos]＋Xave
[New Yos]＝[Preset Yos]＋Yave [New Yos]＝[Preset Yos]－Yave

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:

From data Difference of Min. and Max./2=(0.027+0.004)/2=0.015
(fig40-1) 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 37. 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.
